Wood pellet line

A wood pellet line consists of different machines, depending on the raw material's characteristics. Before the pellet mills, machines reduce the raw material to less than 5 mm and lower its moisture to 12-5%. Usually, a wood chipper and hammer mill reduce the size, and a biomass drying machine reduces moisture. After the pellet mill, a cooler is needed to cool the pellets, and a packing machine is usually needed to pack them into bags. In addition to these main machines, the required accessory machines include a conveyor, blower, cyclone, airlock, de-duster, and electric panel.

The following is the 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 chip 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 cool down the pellets, final pack the pellets into bags by pellet packing machine.

If you are making DIN or EN+A standard pellets, wood bark cannot go into the pellets, so you need wood debarking machines at the beginning of the pellet line.

For details, please refer to the explanation below:

1. Disc wood chipper

For a small-capacity pellet line, a disc wood chipper is much more economical, takes up less installation area, and is easy to operate. For a big pellet line, a drum wood chipper is better.

Model	Motor power	Capacity	Max feed wood diameter	Weight
BX680	22Kw	2-3t/h	13cm	1370Kg

2. Rotary drum dryer

A rotary drum dryer is the best machine for drying wood chips; it can reduce moisture to 12-15%. The system is simple, safe, and easy to operate, with both heating source and electricity savings. The rotary drum dryer uses wood waste, wood logs, and tree branches as its heating source.

Model	Motor power	Capacity	Drum diameter	Drum length
HJ1200	11Kw	1-1.2t/h	1.2 m	12m

3. Water drop hammer mill

The water drop hammer mill is widely used in wood pellet lines to crush wood chips into sawdust because it offers better quality and stability. The control system uses chain reaction technology, which supports production-line control.

We usually recommend a dryer before the hammer mill in a pellet line because dried chips are easier to crush, which saves electricity in the crushing step. Also, if raw material moisture is too high, it is harder to crush because wet material sticks to the sieve and blocks the holes.

Model	Motor power	Capacity	Rotating speed	Hammer quantity
ZW40A	37Kw	1-1.5t/h	2980rpm	56 pcs

4. Ring die wood pellet mill 

Ring Die Pellet Mill MZLH420 is the most popular machine for assembling a pellet line because the technology is mature, easy to operate, runs stably, and produces high-quality pellets.

Model	Motor power	Capacity	Dimension	Weight
MZLH420	90Kw	1-1.2t/h	2900x1100x2150mm	3000Kg

5. Pellet cooler

The contraflow cooler is the best cooling machine in the wood pellet line; it cools wood pellets from 70-80 Celsius to room temperature. The cooler also includes a vibration sieve to remove small particles from the pellets.

Cooling the pellets before packing can improve pellet hardness.

Model	Motor power	Capacity	Blower motor	Airlock model
SKLN1.5	1.5Kw	1-1.5t/h	5.5Kw	GTD2.8

6. Pellet packing machine

This is a quantitative weighing machine with bag sealers. It weighs pellets, fills bags, and seals them. We offer two sealer types for plastic and woven bags.

Model	Motor power	Weight range	Packing speed	Tolerance
100A	0.37Kw	10-100kg/bag	≤300 bags/h	0.2%F.S
