 2T/H straw pellet plant production process

  1. 【Feeding and transportation】: The purchased straw is fed into the feeder by the loader, and then transported to the straw crusher through the conveyor belt. (The volume and humidity of straw, corn stalks, wheat straw and other straws are relatively large (about 25%))
  2. 【Crushing and cyclone separation】: Due to the large volume of straw, corn stalks, wheat straw and other straws, they need to be crushed by a grinder first, and the particle size of the crushed particles is 21mm. The discharge port at the tail of the straw pulverizer is connected to the cyclone dust collector, and the material is separated by the principle of material rotation dust removal.

    The dust particles with high density are thrown to the wall of the device and fall into the cone under the action of centrifugal force, and the dust particles with low density enter the bag filter with the exhaust gas for treatment.
  3. 【Conveying and storage】: The crushed material after cyclone separation falls into the conveyor belt from the bottom of the cone of the cyclone dust collector, and is transported to the broken material storage area by the conveyor belt for storage.
  4. 【Feeding and conveying】: After the stored crushed materials are fed into the feeder by the loader, they are conveyed to the screening machine through the conveyor belt.
  5. 【Sieving, airtight transportation】: Since the crushed straw may contain insufficiently crushed fragments, the crushed fragments are sent to a sieving machine (filter mesh diameter 15mm×15mm) for screening, and the crushed straw with a particle size greater than 15mm The material is manually cleaned and returned to the crushing process, and the crushed material with a particle size of less than 15mm is directly transported to the dryer through a closed auger conveyor.

    (The crushed material screening process of this 2t/h straw pellet plant project will produce unqualified crushed materials, about 100t/a of unqualified crushed materials (50t/a in the first phase), and the generated unqualified crushed materials will be returned to the crusher for re-grinding.)
  6. 【Drying】: Biomass pellets have strict requirements on the moisture content of raw materials. Due to the different sources of purchase, the purchased straw and straw have a high moisture content (about 25%) due to rain or irregular stacking.

    In order to ensure product quality, this 2t/h straw pellet production project uses a straw dryer (using the flue gas produced by the biomass hot stove to directly heat and dry, the drying temperature is 280~450℃), so that the moisture content can meet the granulation requirements (about 10%).
  7. 【Conveying and storage】: The broken material after cyclone separation falls into the conveyor belt from the bottom of the cone of the cyclone dust collector, and is transported to the broken material storage area by the conveyor belt for storage.
  8. 【Feeding and conveying】: The dried crushed material is fed into the feeder by the loader, and then conveyed to the straw granulator through the conveyor belt.
  9. 【Pelleting and forming】: The dried crushed material is fed into the extrusion chamber of the straw pellet machine by the loader, and the crushed material is squeezed into the inner hole of the mold by the pressing roller, and is formed by hot extrusion of the mold. (Related product:biomass pellet mill for sale

    (During the compression molding process, the friction of the material generates heat (about 40℃), and the extruded material is cut into cylindrical particles at the outlet of the straw pellet mill. The whole process is a physical extrusion molding without adding any binder.
  10. 【Conveying and packaging】: After the finished product comes out of the discharge port, after cooling naturally, it is transported to the finished product hopper through the conveyor belt, and then sold after manual packaging.

[Case 2] Biomass fuel 2 t/h straw pellet plant project

Origin of the project

In the 21st century, straw is regarded as a green and renewable energy with a large scale of development and utilization. Crop straw contains a variety of effective components that can be used.

In addition to the vast majority of carbon, it also contains potassium, silicon, nitrogen, calcium, magnesium, phosphorus and other elements as well as cellulose, hemicellulose, lignin, protein, Amino acids and other organic components.

Research by the International Energy Agency shows that straw is a good clean and renewable energy source.

After the straw has been hot-pressed to a certain density and then burned, it can increase the combustion temperature and heat utilization rate, reduce the pollution of the air environment, and the burning speed is fast, saving time, making the straw a high-grade energy product and protecting the ecological environment.

2T/H straw pellet plant process flow

  1. Raw material straw: The biomass raw material is temporarily stored in the storage yard.
  2. Crushing and screening: Due to the large size of crop straws, they cannot be directly used for molding processing. The main task of the crushing process is to crush the larger straws into short and fine granular raw materials with a straw crusher.
  3. Biomass pellet machine molding: the raw material is extruded by a biomass pellet machine. The crushed material is fed into the biomass pellet machine. In the biomass straw pellet making machine, the crushed material is heated.

    And the heat source comes from the heat generated by the friction between the mold and the material and the heat generated by the friction between the materials due to the compression volume shrinkage.

    Under the action of a certain temperature and huge pressure, the lignin in the crushed material is melted into a “glue”, and the raw material is pressed and glued into a solid object, which is extruded from the ring die hole of the straw pellet mill and extruded into this product. Project product – solidified fuel.

    The cylindrical solidified fuel is continuously extruded from the straw pellet machine, and cut into the required length by the cutting machine according to the market demand. The cut solidified fuel is conveyed to the packaging section, and the solidified fuel is naturally cooled during the transportation process.
  4. Packaged finished product: The solidified fuel that is cooled during the transportation process is measured, packaged, and sealed in sequence before being stored in the warehouse. (Related solution: 2T/H biomass pellet manufacturing plant
