Wood pellet line

pellet line.jpgWood pellet line is made up of different machines according to the features of different kind of raw material. Before pellet mill need machines to process the size of raw material small than 5mm, process the moisture of raw material to 12-15%. Usually use wood chipper and hammer mill to process the size, use biomass drying machine to reduce the moisture. After pellet mill a cooler is needed to cooling down the pellets, a packing machine is usually needed to pack the pellets into bags. Aport from these main machines, the needed accessory machines is conveyor, blower, cyclone, airlock, de-duster and electric panel.

The following is an main machine assemble for a 1t/h wood pellet line, consider the raw material is wood log diameter <15cm, moisture 40-50%, for this pellet line first need a wood chipper to chipping the wood logs, then need a rotary drum dryer to dry the wood chips, following that a water drop hammer mill is best choice to turn the chips to sawdust, after this preparation of raw material, pellet mill will use this processed material to make pellets and a cooler to cooling down the pellets, final pack the pellets into bags by pellet packing machine.

If make DIN or EN+A standard pellets, the barks of wood can not go to pellets, so at beginning of pellet line a wood debarking machineis needed.

Water drop hammer mill is widely used in wood pellet line to crush wood chips into sawdust, because the quality and stability of this kind of hammer mill is better. The control system use chain reaction technology, it is a good thing for production line control.

We usually suggest dryer before hammer mill in pellet line, because after drying the chips is easier to crush, and it will save electricity in crushing step. Also for hammer mill if raw material moisture is too high it is not easy to crush, cause the wet material will stick on the sieve and block the holes.
