Beginners Guide for Wood Pellets Production Procedure

Production process of wood pellets

The production process of wood chips mainly includes the following key steps: firstly, the wood raw materials (such as sawdust, sawdust, etc.) are preliminarily processed, including peeling, chopping, and crushing, to obtain uniform particle size; Next, dry these particles to a suitable moisture content (usually 10-15%); Then, the dried wood is compressed and formed into wood pellets through high pressure and high temperature; Finally, the formed particles are cooled and screened to ensure their quality and consistency, and packaged and stored.

Raw Materials for Wood Pellets: round wood,wood logs, wood slabs,.wood branches, wood chips,wood shaving, wood sawdust, wood leaves, wood waste from sawmill, etc.

What equipment are used for the production of wood chips?

Wood Pellets Making Equipment: wood crusher,wood sawdust dryer, wood pellet machine,wood pellet cooler.automatic packing machine.

Description for Wood Pellet Produce Procedure

In industries, the procedure of wood pellets production mainly departs in the following steps: wood materialcrushing, water moisture control, biomass pelletizing, wood pellets cooling, wood pellets weighing and packingIn a wood pellet lime, the pelletizing process is the most important. Equaling to the pelletizing part, the die andthe roller is the most important part in a pellet machine.

wood material crushing:As a general rule, the size of rawmaterial should always smaller than the pellets size. For wood logs orround wood, crushing process by a wood crusher is needed. Then thesmaller wood blocks will be fed into the wood chipper to chip thewood into chips for further use. If you want to make pellets with asize of ómm, or smaller, you will need a wood hammer mill to makethe wood chips into wood sawdust with a size not bigger than 6mm.

water moisture control:To make premium wood pellets, the water moisture of the raw material should be about 12%6. So it isnecessary to remove excess water from the raw material. In industrial pellets production, a wood pellet cooler isusually adopted. For small-scale, You choose to dry the material in the sun or other methods.

Formation of sawdust particles

biomass pelletizing: Wood material through a feeder come into the pelletizing room, where the die and therollers are motioning relatively at a high speed. With the extrusion force and the high temperature forming in therelative motion, the intermolecular forces in wood material molecule have changed. Thus the plasticity of thewood materials has increased, Then the materials are shaped into pellets bv the hole on the die and pushed out.

wood pellets cooling:The pellets come out of thepellet machine is hot and wet. A pelet cooler is usedto bring the temperature down and reduce the watercontent. After cooling, they are harder and easier to store or transport.

wood pellets weighing and packing:A woodpellet packing machine can pack the pellets in plastic bags with the same weight for transport or for sale. Fora large quantity of wood pellets, bulk trucks are need. Bulk pellets are loaded from the pellet mill directly intotrucks for delivery to bulk storage containers. The bulk trucks are more expensive than regular flatbed trucks, buta much more efficient system of processing.

The sawdust pellet equipment produced by Zhengzhou Fude Machinery has the advantages of high efficiency, energy saving, low noise, and low failure rate. It adopts advanced ring or flat mold technology, which can efficiently compress biomass raw materials such as sawdust and straw into shapes. It is suitable for a variety of raw materials without adding adhesives, and the equipment structure is compact and durable, suitable for large-scale continuous production.
