Plant layout design

The plant layout of the 8t/h biomass straw pellet production line in Uruguay project is as follows: the plant entrance is located on the south side of the project area. The project has 1# workshop and 2# workshop. 1# workshop is located on the west side of the project area.

The south side is for office and living, raw material warehouse and finished product warehouse. 2# is located on the east side of the project area. The south side is for raw material warehouse and finished product warehouse, and the north side is for production workshop.

The functional divisions in this project area are clear, the layout is relatively reasonable, the construction layout of the project area and surrounding roads is reasonable, which can meet the transportation of large and small vehicles and on-site activities.

The layout of the plant area can basically meet the production and management requirements, and basically meet the national and local requirements on environmental protection, fire prevention, safety, sanitation and other aspects.

Straw pellet Production process design

1. Raw material preparation
   The straw of this 8t/h biomass straw pellet production line in Uruguay project is purchased from the farmers' farmland. The farmers dry the straw in the field. After drying, the crop straw is put into the crushing and baling machine by grab shovel truck for simple crushing and baling for easy transportation. Finally, the transport vehicle returns it to the plant warehouse for standby.
2. Raw material loading
   The purchased raw materials are placed in the raw material bin for standby use. The raw materials are transported to the feeding port by forklifts and fed manually. Since the raw material particle size is relatively large, the dust generated during the feeding process is less and is discharged in the workshop in an unorganized form.
3. Crushing
   The purchased straw is sent to the crusher for crushing. The dust generated in this process is collected by the air hood, treated by the bag dust collector, and discharged through the 15m exhaust pipe. The discharge port is connected to the sealed conveying pipeline, and the crushed material directly enters the closed silo through the conveyor belt.
4. Granulation
   The raw materials crushed by the crusher are conveyed by belts to the straw biomass pellet machine for extrusion molding to form finished products. The extrusion process is a physical process, without adding any adhesives and no chemical reaction occurs.
   Except for the conveyor connection and the discharge port, the equipment is closed. The dust generated at the conveyor connection and the discharge port is collected by the air hood, treated by the bag dust collector, and discharged through the 15m exhaust pipe.
5. Cooling
   The pellets after granulation are transported to the hopper by a closed belt for cooling. After cooling, they are weighed, packaged and put into storage.
6. Packaging
   After natural cooling, the finished products are sent to ton bags by conveyor belts for packaging, and the finished products are put into storage for sale.

Project construction process

Land leveling

The 8t/h biomass straw pellet production line in Uruguay project leveled the land, mainly using mechanized construction.

Foundation engineering

The foundation engineering mainly involves filling and compacting the site. Construction workers use rollers to roll the land in sections and water the fill to facilitate compaction.

Then they use lifting machinery to lift a special heavy hammer to impact the surface of the base soil, so that the foundation is compacted. Generally, the tamping is 8-12 times.

Main engineering

The main engineering of the construction project mainly involves drilling and pouring, cast-in-place steel concrete columns and beams, and brick wall masonry. The construction project uses drilling equipment to drill holes and then pours reinforced concrete.

When pouring, the pre-mixed concrete is injected, and the concrete is vibrated as it is poured to ensure uniform vibration to prevent the concrete from being unsolid and the slurry from floating up.

Then, according to the construction drawings, the steel bars are mixed and processed, installed on the erected formwork, and concrete is poured in a timely and continuous manner, and compacted to form the concrete.

When the construction project is laying brick walls, the cement mortar is first mixed, and then the line is hung for laying. This section has a long construction period.

Decoration engineering

Use various processing machinery to process wood, plastic steel, etc. according to the drawings, and at the same time make the roof, then use environmentally friendly paint to spray, and finally paint the exposed iron parts. This section takes a short time, and the amount of paint and paint used is small, and a small amount of organic waste gas is volatilized.

In order to reduce the pollution of construction, the construction unit should do the following:

• During the construction stage, the use of sand, stone, brick, cement, commercial concrete, prefabricated components and new wall materials, etc., their radioactive index limits should meet the standard requirements.
  For indoor artificial wood board finishes and artificial wood boards, the free formaldehyde content or free methanol release must be measured to meet the standard requirements. The total volatile organic compounds and free formaldehyde content of coating adhesives, flame retardants, waterproofing agents, preservatives, etc. should meet the specified requirements.
• When decorating the workshop, pollution-free "green decoration materials" and "ecological decoration materials" should be used to prevent them from causing harm to the health of the operators.

Equipment installation

Including construction of roads, greening, water and rainwater pipe networks.

What should be paid attention to when building a biomass straw pellet production line in Uruguay?

Building a biomass pellet plant does not mean that you can just build a factory and buy equipment. You need to pay attention to many issues. RICHI will analyze the issues that need to be paid attention to.

1. The first is the environmental protection issue. Now, the establishment of a factory requires environmental impact assessment and security before it can be carried out.
   Therefore, before building a biomass pellet plant, the environmental protection issue must be solved first, the dust of the equipment must be handled, the noise of the equipment must be reduced, and the safety of the equipment must be guaranteed.
2. The second is the raw material issue. The efficiency of a biomass pellet plant depends largely on the raw materials. If there are a lot of raw materials and the collection is simple and cheap, then this place is suitable for building a factory.
   Secondly, the type of raw material determines your production line process. If your raw material is dry wood chips from a lumber mill, this material can be directly used for pelletizing; if your raw material is large, high-moisture materials such as logs, you need to crush, pulverize, and dry them before pelletizing, which will greatly increase the production cost.
   Therefore, biomass pellet production lines cannot be purchased casually. This requires individual design and planning based on your own situation and needs. The production line plan that suits you is also the least likely to have problems in later use.
3. The third is the equipment problem. Because biomass raw materials are relatively complex, choosing poor quality equipment will affect production operations. The production line involves many types of equipment.
   Choosing a large, reputable, and after-sales guaranteed equipment manufacturer is conducive to later maintenance and maintenance. Compared with the equipment of small companies, the equipment of big brands may not have an advantage in price, but their products have been recognized by the market, and there is no need to worry too much about quality and after-sales.
