4-5t/h Biomass Pellet Line

4-5t/h biomass pellet line is a big pellet line to produce biofuel pellets from biomass material, like wood pellets, rice husk pellets, straw pellets, EFB pellets., etc.

All the final pellets from this pellet line are biofuel pellets, it can be fuel for boilers, power plants, the biofuel pellets is clean energy and very popular in developed and developing counties.

The raw material/feedstock to this biomass pellet line can be any kind of wood material, straw, grass, agricultural waste, rice husk, EFB, and other kinds of biomass material.

The 4-5t/h biomass pellet line belong to the large pellet production line, usually, it is for industrial purpose, people invest such a pellet line, the owner buy biomass material, employ labor to operate the production line and sell the final pellets on market.

To install a 4-5t/h biomass pellet line need a factory of about 1200 square meters, because for such a pellet line there is a lot of machines, the equipment itself takes a lot of places, and there needs a huge place to storage raw material/feedstock and final pellets.

The component of a 4-5t/h biomass pellet line is raw material pre-grinding which usually includes chipper/shredder and hammer mill/wood crusher, biomass drying machine, pellet mills, pellet cooler, pellet packing machine, conveyors, de-dust system, and control panels.

* the raw material pre-grinding is a basic step to make biofuel pellets, it aims to process the size of biomass material <5mm.

for different kinds of material may need different machines to handle it, for example, if the feedstock is wood logs, we use a wood chipper to chipping the logs to chips first and then use a hammer mill to grinding the chips to <5mm size. if the raw material is straw use a hammer mill that can crush them directly, if the raw material is EFB, the EFB shredder, and hammer mill are needed.

* the biomass drying machine plays a significant role in the biomass pellet line because to make pellets need to dry the biomass material to 12-15% moisture content. As we known drying biomass material in large quantity is a big work, especially for the biomass material which has high initial moisture contain like 50-60% or higher. Thus a high-efficiency dyer is very important, usually, for this kind of high moisture evaporation drying process the rotary drum dryer is necessary, and if can put a pellet furnace or sawdust furnace to the dryer is better. A pellet furnace or sawdust furnace has higher efficiency than a traditional biomass stove, it can make enough hot air to the dryer system.

* the pellet mill is an important part of the biomass pellet line, can compress the dried finely biomass material into pellets.

for the pellet mill, the compression ratio is pivotal, for different kinds of biomass material, the compression ratio of ring die is different, if the compression ratio is not correct the pellet mill can not make good pellets.

* pellets from pellet mill are hot, it can not pack into bags directly, need a cooler to cool it to room temperature. Another reason for need cooler is the hot pellets storage together will get cooling slowly, during the storage period the surface of the pellet will get crack, with the counter flow cooler, the pellets do not crack and the surface can keep shiny and the hardness of pellets will be got better. Packing is the last step in a pellet line, we have different methods of packing: pack the pellet in small bags 10-100kg, and pack the pellets in 500-2000kg big bags, we can make a solution of packing according to client requirement.

* The control system is important to a big biomass pellet line, there needs to have a chain reaction, need to have an overload protection system.

* the de-dust device is essential to a big biomass pellet line, because of the big output, during machine working there is a lot of dust, especially in hammer mill and dryer must need a de-dust device to control the dust. As a reason, if dust is too much in a factory it may explode, so after hammer mill, rotary dryer, pellet mill, the cooler we have a de-dust system connect to the main machines.
