4-5t/h Biomass Pellet Line

4-5t/h biomass pellet line is a large pellet line that produces biofuel pellets from biomass materials such as wood pellets, rice husk pellets, straw pellets, EFB pellets, etc.

The final pellets from this pellet line are biofuel pellets; they can fuel boilers and power plants and are a clean energy source popular in developed and developing countries.

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

The 4-5t/h biomass pellet line is a large pellet production line, usually for industrial use. When people invest in such a pellet line, the owner buys biomass material, employs labor to operate the production line, and sells the final pellets on the market.

To install a 4-5t/h biomass pellet line, you need a factory of about 1200 square meters because this pellet line has many machines; the equipment itself takes up a lot of space, and you need a large area to store raw material/feedstock and finished pellets.

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

* Raw material pre-grinding is a basic step to make biofuel pellets; it aims to process biomass material< 5 mmm.

Different materials may require different machines; for example, for wood logs, we use a wood chipper to chip the logs first, then a hammer mill to grind the chips to < 5 mm. If the raw material is straw, use a hammer mill that can crush it directly; if the raw material is EFB, you need an EFB shredder and a hammer mill.

* The biomass drying machine plays a significant role in the biomass pellet line because, to make pellets, the biomass material needs to be dried to 12-15% moisture content. As we know, drying biomass in large quantities is a big task, especially for material with a high initial moisture content, like 50-60% or higher. Thus, a high-efficiency dryer is essential; for this kind of high-moisture evaporation drying process, a rotary drum dryer is usually necessary, and adding a pellet furnace or sawdust furnace to the dryer is better. A pellet furnace or sawdust furnace is more efficient than a traditional biomass stove and can supply enough hot air to the dryer system.

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

For the pellet mill, the compression ratio is pivotal. Different biomass materials require different ring-die compression ratios; if the compression ratio is incorrect, the pellet mill cannot make good pellets.

* Pellets from the pellet mill are hot; they cannot be packed into bags directly and need a cooler to cool them to room temperature. Another reason for needing a cooler is that hot pellets stored together cool slowly; during storage, the pellet surface can crack. With a counter-flow cooler, the pellets do not crack, the surface stays shiny, and pellet hardness improves. Packing is the last step in a pellet line. We offer different packing methods: small bags (10-100 kg) and large bags (500- 2000 kg). We can provide a packing solution according to client requirements.

* The control system is important for a big biomass pellet line; it needs to have a chain reaction and an overload protection system.

* The de-dust device is essential for a big biomass pellet line because, due to the big output, during machine operation there is a lot of dust, especially in the hammer mill and dryer; a de-dust device is needed to control the dust. For this reason, if dust is too high in a factory, it may explode; so after the hammer mill, rotary dryer, pellet mill, and cooler, we have a dust-collection system connected to the main machines.
