In recent years, RICHI ring die pellet mill design and manufacture have made continuous progress, and the appearance and performance of ring-die pellet mill for animal feed have been continuously improved. In actual production applications, the ring die granulator we produce has a long service life and high production efficiency.

After comditioning, the crushed materials are evenly fed into the wedge-shaped space formed by the two pressing rollers and the ring die by means of gravity, centrifugal force generated by the rotation of the ring die and the action of the feeding scraper. The minimum gap between the pressure roller and the inner wall of the ring die is only 0.1~0.3mm.

Under the strong squeezing action of the ring die and the pressure roller, the material is gradually compacted, squeezed into the die hole of the ring die and formed in the die hole. Because the extrusion of the material between the die and the roller is continuous, the formed material is continuously discharged from the die hole in a columnar shape, and then cut into pellets of the required length by the cutter, and then enters the next process.

Due to the wide applicability of the RICHI pellet milling machine, the output of the same pellet mill equipment when processing different granules is different, the preparation work before granulation is also different, and the requirements of different customers for the granules are also different. It may be the difference of pellet mill die compression ratio, or it may be customized pellet mill for special needs. However, no matter what your requirements for the pellet milling machines are, RICHI can help you achieve it. (Hot project: 3-5T/H Commercial Poultry Feed Mill in Malaysia)

Due to problems such as process design and operation technology in the animal feed mill factory, the quality and output of the finished product cannot meet the expected requirements, and the surface of the pellets is not smooth, the powder content is high, fragile, and uneven. According to practical analysis, the main reasons affecting the efficiency of pellet mill for animal feed are as follows.

01

Raw materials

Materials with high starch content are easy to be gelatinized. After conditioning, these raw materials are viscous and easy to shape. Raw materials with high crude fiber will increase the friction force of the feed pellet mill ring die, so a certain amount of grease should be added to facilitate the material to pass through the die hole, and the surface of the finished product is smooth.

From the perspective of granulation process, if the crushing is too fine, the granulation strength will increase; if the granulation is too coarse, the wear of the ring die and pressure roller will be increased, and the forming will be difficult, resulting in low output and high powder rate. (Related case: Qatar 3-4T/H Poultry Cattle Feed Pellet Mill)

Therefore, different raw materials need to adopt different crushing diameters. Such as livestock and poultry feed, crushed corn is recommended to use 2.5~3mm sieve plate. In addition, different raw materials have different formulations, and the mixing time is also different. Before granulation, pay attention to the uniformity of mixing, so that the mixing coefficient can reach about 5%.

02

Feed control

Many animal feed mills only consider the problem of pelleting when the production efficiency becomes low, ignoring the control of incoming materials. In practice, the feed flow directly affects the granulation speed. At this time, it is necessary to find out whether the feed flow rate is unstable, so as to find out the cause, effectively eliminate the intermittent situation when feeding, and ensure that the pellet mill for animal feed does not stop and works evenly at full load.

01

Production operation

Correctly adjust each part of the animal feed granulator. The die and roller are generally controlled at 0.05-0.30 mm, so as to avoid being too small or too large, causing noise and affecting material granulation. The gap between the upper edge curve of the scraper and the die and the die cover is basically controlled within 2-3 mm. Turn on the pellet mill for animal feed, observe whether there are granules out of the mold smoothly, and pay attention to the change of current.

In order to prevent the debris in the machine from entering the die, the discharge door outside the machine on the operation door should be opened to discharge the material mixed with impurities in the machine. After the miscellaneous materials are cleaned, the materials can be introduced into the die.

01

Ring die

The coefficient of friction between the material and the die wall, moisture content, raw material particle size, temperature, material plasticity and material compressibility all affect whether the material can be released from the mold smoothly. These are closely related to the aperture and depth of the ring die. (Related project: Senegal 3-5T/H Poultry Feed Pellet Plant)

It is recommended that the die diameter be reduced by 1:8 to 1:13 (that is, the effective thickness ratio of the die hole to the die). If the compression ratio is too small, the time for the material to pass through the aperture is short and the efficiency is high, but it is easy to loosen and the surface smoothness is low; on the contrary, the longer the effective length of the compression hole, the greater the pressure of the material and the higher the compactness of the finished product, but the output decreases and the energy consumption will increase.

Therefore, users can choose the compression ratio of the ring die of pellet mill for animal feed according to their own needs. The compression ratio of the ring die for livestock and poultry pellets is generally below 10, and the compression ratio of the ring die for aquatic pellets is mostly above 10.

• During the production process, when too much material enters the pellet making machine for animal feed and the current rises suddenly, the manual discharge mechanism must be used to discharge the material outside the machine.
• When it is necessary to open the door of the food granulator, the power must be cut off first, and the door can only be opened after the pellet mill for animal feed has completely stopped.
• When restarting the granulator, the ring die of the feed granulator machine must be manually turned (one circle) before the animal feed granulator can be started.
• When the machine breaks down, the power supply must be cut off and the machine must be shut down to remove it. It is strictly forbidden to use hands, feet, wooden sticks, and irons to remove it hard during operation; it is strictly forbidden to start the motor hard.
• When using a new ring die for the first time, a new pressure roller must be used, and oil can be mixed with fine sand (all through a 40-20 mesh sieve, the ratio of material: oil: sand is about 6:2:1 or 6: 1:1) Wash the ring mold for 10 to 20 minutes, then it can be put into normal production. (Related case: Uzbekistan 3-5 Tons/Hour Poultry Feed Plant)
• Assist the maintenance worker to check and refuel the main motor bearing once a year.
• Assist the maintenance workers to replace the lubricating oil for the gearbox of the pellet mill for animal feed 1-2 times a year.
• The permanent magnetic cylinder should be cleaned at least once per shift.
• The steam pressure entering the conditioner jacket is not higher than 1kgf/cm2.
• The pressure range of the steam entering the conditioner is 2-4kgf/cm2 (generally not less than 2.5 kgf/cm2 is advisable).
• Oil the pressure roller 2-3 times per shift.
• Clean the feeder and conditioner 2-4 times a week (clean once a day in summer).
• The distance between the cutter and the ring die is generally not less than 3mm.
• 14)During normal production, it is strictly forbidden for the main motor current to exceed the rated current, that is, overload operation.

Pellet feed processing technology has been used for many years, and pellet feed has been widely used in livestock and poultry feeding (including pig feeding). Pellet feed can be made from single feed or formulated complete feed through pressing technology. The pellet feed is usually cylindrical and has different sizes.

According to different types of feed, it is necessary to determine different sizes of pellets, so as to be more suitable for biological diversity and more conducive to the absorption of subsequent nutrients. (Related case: Zimbabwe 3-5T/H Broiler Chicken Feed Mill)

Because chickens like to eat pellets or broken grain materials, they can be used in combination of thickness and thickness. Paddy and broken rice can be directly added to the mixer in granular form. The crushing fineness of wheat and barley should be below 2.5 mm. Corn, brown rice and bean cake should be processed into powder.

When laying hens need calcium supplementation to produce soft-shell eggs, it is ideal to feed granular calcium, that is, grind limestone, shells, etc. into sorghum grain-sized particles, and then feed them at the last feed every night. Because granular calcium stays in the chicken body for a long time, it is beneficial to the absorption and utilization of the chicken body, so the effect of calcium supplementation is good.

Beans and other energy feeds can be fried and fed. Piglets under 25 kg can be fed with general piglet feed; piglets over 25 kg can be fed with crushed fineness within 2 mm. The feed for pigs should be crushed as finely as possible.

Because cattle can ruminate, a slightly thicker feed is conducive to rumination and improves feed digestibility. The feed of old cattle and sheep can be crushed to less than 1 mm to facilitate digestion.

The fineness of crushing should not only consider the types of livestock and poultry, but also take into account not to crush fat-rich grain feeds such as corn and oats too finely, and store them for too long to avoid rancidity.
