Mechanism of Sawdust Pellet Press

Raw material granulation standard: about 15% moisture

The main material form of biomass is pellets of different sizes. The filling characteristics, flow characteristics and compression characteristics of particles during the compression process have a great influence on the compression molding of biomass. Usually biomass compression molding is divided into two stages.  (Related product: Wood Pellet Mill)

  • The first stage: In the early stage of compression, the lower pressure is transmitted to the sawdust pellets, which changes the arrangement structure of the solid particles that were originally loosely packed, and reduces the internal void ratio of the biomass.
  • The second stage: when the pressure is gradually increased, the large biomass particles are broken under the pressure and become finer particles, and deformation or plastic flow occurs, and the particles begin to fill the gaps, and the particles are more closely contacted and meshed with each other. Part of the residual stress is stored inside the forming block, which makes the combination between particles stronger. Pressure, water content and particle size are the main factors affecting the change of sawdust particles during compression.

Raw materials requirements for sawdust pellet press machine

There are many factors that affect the formation of biomass wood sawdust pellets. In addition to the performance of the sawdust pelletizing equipment, it largely depends on the performance of the raw material and the wood sawdust pelletizing process.

  • Wood: waste wood chips and shavings from board factories and furniture factories, waste sawdust from logging yards, scraps, building board waste, garden pruning, forest logs and other miscellaneous wood.
  • Bamboo scraps: Bamboo handicraft waste, such as chopsticks, toothpick factories and other waste.sawdust pellet press wood pellet presses pellet mill pellet press 2.2 kw 230v other woodworking supplies
  • Grass stalks: cotton corn stalks, soybean stalks, rape flower stalks, wheat straws, rice straws, cassava stalks, bagasse, tobacco stalks, seabuckthorn stalks and other herbaceous plant stalks, energy grass, elephant grass, giant king grass, Alfalfa grass (for cattle and sheep feed).
  • Other categories: rice husk, peanut shell, bagasse, palm fiber (fruit bunch), coconut shell, cow dung, pomace, etc.

Taking wood as an example, waste wood chips from board factories and furniture factories do not need to be crushed and dried, and can be used after screening; building board waste needs to be crushed before use, and the particle ash content is relatively large; waste sawdust and leftover materials in lumber yards do not need to be crushed, However, it needs to be dried, and the particle ash content is low; while garden pruning, forest logs, etc. may also need to be peeled. (Related case: Canada 2-3T/H Wood Pellet Plant)

According to different raw materials, the pellets can be divided into biomass peanut hulls, rice hull pellets, miscellaneous wood pellets, pine wood pellets, sylvestris pine pellets and so on. The type of raw material determines the calorific value of the produced biomass pellet fuel.

Why is the ring die sawdust pellet press popular with investors?

01

Good market prospects

Traditional energy can no longer meet the needs of the global market. Biomass wood pellet fuel, as a substitute for coal, can just make up for this energy gap.

02

Sufficient source of raw materials

The annual output of biomass energy such as straw exceeds the total energy demand, and as a renewable resource, their reserves are very abundant. Therefore, it currently has a good market prospect as an energy source.

03

High profit

The raw materials of the ring die sawdust pellet press machine are crop stalks and so on. The cost of these materials is low, the cost per ton is low, and the processing output of the sawdust pellet mill machine is high. In the face of huge market demand, the industry has considerable profits. (Related solution: Biomass Pellet Plant)

How much wood pellets can be produced from 1 ton sawdust raw materials?

Customers who want to get involved in the sawdust pellet production industry have a question: how many pellets can be produced from one ton of wood chips? RICHI believes that this problem can be considered from three aspects: raw material moisture, raw material purity, and sawdust granulation equipment.

01

Look at the purity of raw materials

Look at the purity of the raw material. The higher the purity, the higher the particle yield. If the raw material has been screened, crushed, and dried, one ton of raw material can produce more than 0.9 tons of pellets. (Related post: 5T/H Wood Pellet Factory In Austria)

02

Pay attention to the humidity of raw materials

The temperature of finished granules and raw materials is inseparable, and the moisture content of raw materials is strictly required during granulation, which should be controlled at 13-18%. If the raw material is too wet, it needs to be dried, and the drying process will take away part of the water, so the greater the moisture in the raw material, the less raw material will be obtained after drying, and the output of finished pellets will be less.
sawdust pellet press wood pellets press machine

03

Good sawdust pellet press

If you want to produce more finished granules, it is not enough to only look at the purity and humidity of the raw materials, you also need to have good sawdust pellet press. With a wood sawdust pellet pressing machine with high output and low energy consumption, the pressure roller and the mold are properly matched, and the forming rate of the pellets can reach more than 95%.

If you encounter unqualified equipment, the forming rate can reach 50%, which is already good. Therefore, when purchasing, you must purchase equipment from regular manufacturers, so as not to affect production efficiency and cause economic losses.

04

Daily maintenance of sawdust pellet pressing equipment

In recent years, biomass projects have become more and more popular, but some friends do not pay attention to maintenance after normal production, which has caused an invisible increase in costs, so that the gains outweigh the losses. The maintenance of sawdust pellet equipment is the key to control energy consumption. After maintenance, the life of the machine will be longer and the quality of pellets will be better.

  • Neat. The tools are placed neatly, the safety protection devices are complete, and the pipelines are complete.
  • Clean. The inside and outside of the workplace and equipment are always kept clean, free of dust accumulation and grease stickiness, etc., and all kinds of workplaces and equipment do not leak materials, oil, water, or air during operation, and clean up garbage and leftovers.sawdust pellet press pellet press pellet mill pellet machine wood pellets biomass fuel
  • Lubricate. Refuel and change the oil regularly, the oil quality meets the requirements, the oil pot and the oil cup are complete, the linoleum, the oil line, the oil mark are clean, and the oil passage is smooth. (Related solution: Wood Pellet Production Line)
  • Security. Workers must abide by the operating procedures. All kinds of power equipment and main operating machines have the specified load operation conditions. There are no missing parts, rope binding, strange sound and smell, abnormal vibration or swing of various equipment, and all kinds of measuring instruments are working normally. Regularly check various protective devices and power equipment.

What is the difference between a vertical and horizontal sawdust pellet press?

There are two commonly used biomass pellet machines, the first is a vertical pellet machine for sawdust, and the second is a horizontal pellet machine. At present, all well-known manufacturers in the world adopt the structure of horizontal ring die sawdust granulator. What are the specific differences between these two models? Today, RICHI will tell you the difference.

01

Discharge method

  • Vertical saw dust granulator: transported up to the silo by the conveyor belt.
  • Horizontal saw dust granulator: free fall to the discharge port.

02

Motor Power

  • Vertical sawdust pellet granulator: The power of the motor is small, and the production is generally overloaded, basically reaching the power value of the model data.
  • Horizontal sawdust pellet granulator: The power of the motor is large, and it is not easy to overload the production.sawdust wood pellet press for sale wood pellet press machine

03

Feeding method

  • Vertical sawdust pellet machine: feeding vertically by the auger.
  • Horizontal sawdust pellet machine: uniform feeding, composed of feeding and modulator, uniform feeding.

04

Mechanical structure

  • Vertical sawdust pellet making machine: The gear reducer is a rigid transmission, with small power loss and relatively high noise. The key to the coupling connection is the reliability of the concentricity connection. (Related project: 1-1.5T/H Wood Pellet Production Line in Indonesia)
  • Horizontal sawdust pellet making machine: The belt transmission is stable, the installation requirements are low, the noise is small, and the overload protection is easy to realize.

The above is the comparison between the vertical pellet press granulator and the horizontal pellet press granulator. It can be seen that:

The vertical sawdust pellet press has a simple structure, a small footprint, low price, short life, easy to break down, and frequent and troublesome replacement parts. The horizontal saw dust pelleting press machine has a reasonable structure, heavy weight, large floor space, high price, and a long service life that is three times longer than the vertical pellet machine. It is efficient, high hourly output, low maintenance, and low frequency of replacement of wearing parts.

To sum up the above points, combined with the difference between the horizontal pellet machine and the vertical pellet machine in the production process, the following points are obtained: the horizontal pellet machine produces stable pellets, the sawdust pellet processing machine has few failures and is easy to maintain, the hourly output is high, and the motor power is stable.

Precautions for sawdust pellet press operation

  • Operators should carefully read the instruction manual and be familiar with the various technological processes of the equipment before using the machine.
  • During the production process, it is necessary to operate strictly in accordance with the regulations and sequence, and perform installation operations according to its requirements.
  • The host equipment needs to be installed and fixed on the horizontal concrete floor, and the screws should be tightened.
  • Smoking and open flames are strictly prohibited in the production site.
  • Investigate the marketing channels and determine the type of feed to be produced. Including feed quality and output requirements, and determining the formula for feed processing.sawdust pellet press presswood pellet wood pellets press machine
  • After each start-up, it needs to idle for a few minutes first, and confirm that the pressure roller fits the mold and rotates before feeding.
  • It is strictly forbidden to add hard debris such as stones and metals to the feeding device, and remove iron before granulation to avoid damage to the granulation chamber.
  • During the operation of the equipment, it is strictly forbidden to use hands or other tools to remove materials to avoid danger.
  • If there is abnormal noise during the production process, the power supply must be cut off immediately, and the machine can be started to continue production after checking and handling the abnormal situation.
  • Before shutting down, first stop the auxiliary feeding, and then put in the oil, and wait until the mold hole is filled with oil and the granulation chamber is empty of oil before shutting down. The purpose of feeding oil is to make it easier to discharge during the next production.

Correctly operate the sawdust pellet press machine as required, and pay attention to relevant matters as required, not only can improve the output and operating performance of the equipment, but also prolong the service life of the equipment.

Customer Guide Of Sawdust Pellet Press

How does a sawdust pellet press machine work?

How a pellet press works? The working principle of the animal feed pellet press and the wood pellet mill granulator is based on the working principle of the ring die pellet pressing machine. However, due to the different materials to be pressed, there are differences in the specific equipment configuration, so here, RICHI explaines the working principle of the two types of pellet press equipment separately.

The wood sawdust pellet press can be used to compress various biomass raw materials, agricultural and forestry waste, urban waste, organic fertilizer, waste tires, organic plastics and other pellets. The wood pellet pressing machine is operated in direct connection with a motor. The motor is connected to the shaft of the reducer through a gear coupling. After a 90°change of direction, the horizontal motor drives the vertical casting hollow transfer spindle, and the spindle drives the roller to roll the die. The inner surface completes the pressing process.
wood pellet press for sale sawdust pellet press

When working, the biomass wood material falls vertically from the feed inlet, and the material is continuously and evenly distributed on the surface of the mold cavity through the rotation of the pressure roller (the contact surface of the pressure roller and the pressing die), and the powdery material is crushed by the pressure roller holes through the mold (holes evenly distributed on the inner surface of the die). In this process, the material is subjected to high pressure and high temperature to produce physical changes or appropriate chemical changes (according to the material), which promotes the powdery material to form a continuously elongated cylindrical solid body, and then the pellets are cut by a knife and discharged from the discharge port. The pressing process of the pellets is completed.

How to choose sawdust fuel pellet press manufacturers in China?

With the rapid development of feed, biomass energy, organic fertilizer, chemical industry and other industries, the market demand for pellet mills is also increasing year by year. At present, most of the pellet press manufacturers are small and medium-sized, and the production technology is also at the stage of gradual maturity, and the product quality of the pellet press is also uneven. Therefore, you must pay attention to a few points when choosing a pellet press manufacturer, because after all, you are not buying a small item, so you must be cautious when buying equipment.
wood pellets press machine sawdust pellet press

  1. First of all, we must inspect several pellet making machine manufacturers, and investigate the strength, reputation, scale, etc. of the pellet mill manufacturer in all aspects.
  2. Try to visit the production plant of the pellet press manufacturer as much as possible, and inspect the company's product quality, production technology, technical level, and production maturity. If possible, it is best to let the manufacturer of pellet press take the customer to visit the production site they make for the customer, because the user's on-site speaking is authoritative and convincing.
  3. Choose the appropriate equipment according to the customer's own site conditions and planned output. In addition, if the equipment should fail during operation, how to solve it, you should have a clear after-sales plan with the manufacturer.
  4. When signing the order contract with the pellet press manufacturer, you should carefully read the order contract. If you find any omissions, you should add it in time to avoid unnecessary economic disputes after signing the contract.
  5. The pellet press manufacturer is providing customers with on-site installation services. The company will send technical service personnel to participate in the unpacking acceptance and guide the installation and commissioning work until the equipment is operating normally, and provide corresponding technical training services.
  6. Finally, it is necessary to explain that customers should pay special attention when choosing equipment, and determine those companies that have entities and which are non-physical companies, so that customers can avoid detours when purchasing equipment and avoid unnecessary economic losses.

Attention points for operation

Note: When operating, not only should the safety attention points be strictly followed, but also the safety specifications and variety regulations for protection against accident enacted by the owner's enterprise need to be obeyed.

  1. Pay attention to the place where dangerous marks are attached.
  2. The safety protection devices can never be dismounted, covered or overlapped at will.

Preparation work

Prior to start, the following work should be done:

  1. Open the main door and its sided protection guard;
  2. Clean the pelleting chamber, check the feeder and conditioner;
  3. Check the installation condition for rind die, and check the proper adjustment for press rollers.
  4. Check and adjust the intervals between the pellet cutting knives and outer surface of ring die;
  5. Fill lubricating oil;
  6. Check the steam system. The delivery pressure should be within 0.7-1.0Mpa and the working pressure should be between 0.1-0.4Mpa.

Pelleting operation

★Start up

Following work should be prepared before startup:

  1. Open the front door;
  2. Clean the pelleting chamber, check the feeder and conditioner;
  3. Check the installation condition for ring die and the proper adjustment for press rollers. Pay attention to the gap between press rollers and ring die;
  4. Fill lubricating oil;
  5. Start up the feeder motors for feeder and the conditioner without load to check if the rotation direction is correct and there is any noise; and then shut them down when the feeder operates at low speed;
  6. Start up the motor of cooling system and the main motor. Firstly check and ensure that all the pellet press components are operating correctly; check and ensure the ring die rotates clockwise from front view. Then inspect the contact condition between the press rollers and the inner surface of pellet pressing die, which should rotate smoothly;
  7. Check the steam system. The pressure for the steam enters conditioner should be 0.1~0.4MPa. If there exist jacket, the steam pressure enters the jacket should be within 0.1MPa.sawdust pellet press automatic diesel pellet press biomas wood pelletshammer mill animal feed other agriculture farming

★Pelleting

To start up a new pellet press or the pellet pressing machine with new installed pellet press dry pressing die, the following procedures should be followed:

  1. Start up the motor of cooling system and the main motor of the pellet press mill.
  2. Feed certain amount of oily coarse mash to the inlet of the pellet pressing mill manually, and continue feeding until feed pellet is formed. This is the primary lubrication for the ring die before normal production.
  3. Start up the main motor of conditioner.
  4. Start up the feeder motor, adjust the frequency converter to low frequency and let the feed enters conditioner slowly. Do not add any steam in the beginning of pelleting. Increase the feeding speed slowly according to the current of main motor.
  5. Open the steam valve a little, then increase the feeding rate until the pointer of ammeter is falling; when the ammeter`s pointer of the main motor reaches the normal load, add steam amount to allow the ammeter`s pointer to fall back. Repeat this procedure until the maximum output and the best quality of pellet are obtained under the rated load.
  6. See pellet pressing process. The feeding amount and steam supply are different depending on the different types of ring dies and formulas, which results different pellet qualities. So that the pellet press operator should be rick in operating experience.

★ Shutdown

The shutdown procedures of pellet press machine are described below:

  1. Turn off the steam control valve of pellet press equipment.
  2. Cut off the feeder motor.
  3. Shutdown the conditioner motor.
  4. Keep the pelleting machine running until no pellet is produced.
  5. If the machine needs certain time to be stopped, for instance, during the end of working day, oily mash material can be fed into the manual-feeding inlet after working until the pellet is formed. As such, it is convenient for the ring die to start up next time.
  6. Shut down the motor of cooling system and the main motor of pellet press mill when it stopped extruding oily pellet.wood pellet press homemade sawdust pellet press

The countermeasure of sawdust pellet press machine

In order to ensure normal and safe operation, the following safety countermeasures should be obeyed.
 

  1. Overload protective device
    This pellet processing machine is equipped with an overload protective device associated with shear pin and limit switch on the main shaft end. When hard impurities enters the pelleting chamber or when the material flow rate is too high with unstable steam flow, the pressure between rollers and pellet press ring die will exceed the normal working pressure. The pellet press roller will drive main shaft to rotate since rollers are installed on the main shaft and the ring die is installed on the rotor. When the torque of the main shaft exceeds the normal design value, shear force on the safety pin exceeds its limit; the shear pin is sheared off. At this time, limit switch stops the motor of pellet press mill and shutdown the machine.
  2. Pneumatic emergency discharge
    A by-pass is provided at the conical feeding inlet. When the materials enters ring die too fast, it will cause accumulation in the pelleting chamber and increase the load of motor. Under such condition, the by-pass will be automatically opened via the pneumatic system, and the feed will be discharged through the by-pass. When the motor load returns normal, the by-pass will be closed automatically and the whole system will continue operating normally.
  3. Safety switch of main door access
    For the safety consideration, the limit switch will cut the power supply and stop the machine from running when the main access pellet press door is opened.
  4. Gearbox cooling system
    Refer to the operation manual of cooling system for further information.
  5. Magnetic separating device
    In order to ensure the cleanness and safety of gearbox, magnetic separating device is located under the gearbox, which can prevent the effect of moving components generated by the scrap iron impurities in lubrication system, and increase the service life for gear, shaft and seals.wood pellet press sawdust pellet press

How to adjust the gap between pellet press rollers and pellet press die?

The correct gap adjustment of press roller is very important, it concerns to whether the sawdust pellet pressing machine can function normally and the service life of pellet pressing roller and pellet pressing ring die. Generally speaking, the gap in press rollers should be controlled within 0.2 ~ 0.5mm. At this time, the roller can only touch the high spots of ring die when the ring die is running at a low speed.

Adjustment procedures:

  1. Loosen the lock bolt of front support assembly.
  2. Adjust the adjusting screw to make the roller move closer to the ring die counterclockwise. In the meanwhile, runt the ring die and roller for one circle. It is better to make the highest spot of inner surface of ring die contacts with that of the outer surface of press roller slightly.
