Description
Sawdust Pellet Production Line
Sawdust is an ideal raw material to make biofuel wood pellets because the preparation work is simple, investment is low, producing procedure is simple and the final wood pellets from sawdust with high bulk density and heating value.
Use sawdust to produce pellets the flowchart is quite easy:
--if the sawdust is not pure, for example, there have a big size wood block in the sawdust, it needs precleaning, usually use a drum sieve to pick out the big pieces from sawdust.
--if the sawdust moisture is higher than 15% need a dryer to dry the moisture before the pellet machine, if moisture is lower than 15% can start from the pellet machine directly.
--after the pellet machine makes pellets, needs to cool down the pellets and pack the pellets into bags for easier delivery.
Advantages of sawdust pellet production line: 1. simple production line, do not need chipper or hammer mill to prepare raw material, because usually, sawdust is around 5mm size, it is good size make pellets 2. small installation area, low power consumption, low investment, and operating cost 3. easy operate, from the electric panel can start to stop the production line directly and the electric panel have a protection system for the motors 4. final pellets with high calorific value, hardness, and bulk density 5. can make 6mm, 8mm, 10mm diameter pellets, length of pellets adjustable 7. the final pellets can meet DIN or EN A-plus standard |
We have 0.5t/h, 1t/h, 1.5t/h, 2t/h, 3t/h, 4-5t/h sawdust pellet line, we can design a larger capacity sawdust pellet line as your request.
Below is the machine description for the 2t/h sawdust pellet production line:
1. Drying part
To make a sawdust pellet, usually drying equipment is necessary, because to make pellets the best moisture is 12-15%, most of the sawdust collected moisture is higher than 15%, so need a dryer to dry the moisture of sawdust lower than 15% is the first step to make wood pellets from sawdust. for a small capacity production line, a flash dryer can do the work, as for a 2t/h sawdust pellet production line, use a rotary drum dryer to dry the sawdust is the best solution, cause the rotary dryer can dry biomass material with a large quantity and high efficiency, the rotating speed of drum tube is adjustable so it can deal with sawdust with different moisture content level. The rotary drum dryer can handle sawdust with initial moisture max to 60-70%.
2t/h drying capacity, our HJ1500 model rotary drum dryer is capable, the diameter of drum tube is 1.5 meters, the length of the drum tube is 12 meters. It applies a single layer (single pass) design, inner the drum tube there is more space for sawdust coming through, sawdust can not block inside.
Model | Motor power | Capacity | Drum diameter | Drum length |
HJ1500 | 15Kw | 2-2.5t/h | 1.5 m | 12m |
2. Pelletizing part
Pelletizing part is the most important part in a 2t/h sawdust pellet production line, it includes the conveyor feeding system, hopper storage for pellet mills, pellet mills, and automatic control system, the sawdust goes to the storage hopper from a belt conveyor or screw conveyor, then from storage hopper feed to the pellet mills.
Use two sets MZLH420 horizontal ring die pellet mill to get 2t/h output wood pellet is the best solution because the MZLH420 model is the best most among the horizontal ring die pellet mill, it has good performance and stability. Use two sets pellet mill have another advantage: if one pellet mill is under maintenance you can still use another one to continuous make pellet.
The MZLH420 ring dies pellet mill equipped feeder and force feeder. the feed auger is VFD control it can adjust the feeding speed to avoid sawdust block in pelletizing chamber because of overload. The force feeder and feeder scraper can help to push the sawdust into the ring die, thus to improve productivity.
Model | Motor power | Capacity | Dimension | Weight |
MZLH420 | 90Kw | 1-1.2t/h | 2900x1100x2150mm | 3000Kg |
3. Cooling and packing part
The cooler is necessary for big capacity pellet line because from the pellet mill temperature of pellets is up to 60-80 celsius, if cooling by nature or cooling too slowly the surface of pellets will crack, so an efficient cooling system is important after pelletizing part, that is why it needs a counterflow cooler after pellet mill.
The counter flow pellet cooler includes the cooler main body, de-dust system, feeding airlock, and discharge system, together with the cooler also have a pellet sieve. The cooler can cool the temperature of pellets to room temperature, from the electric panel can adjust the cooling time, the whole system is automatic work under the control of the electric panel. The pellet sieve is used to pick out the small pellets or powder from pellets so that only the good pellets go-to packing or storage, the small pellets or powder can go back to the pellet mill to make pellets again.
Aftercooler some clients require a packing machine to pack the pellets into bags, some clients require a big storage tank to store the pellets and deliver the pellets directly without packing. We can make the design as a client requirement.
We have a packing machine to pack the pellets, it can weigh the pellets to a value set in the PLC controller, discharge pellets to bags, and seal the bags. The accuracy of the packing machine is high.
