The classification of pellet mill for sale

According to the difference of finished products, there are two kinds of pellet mill machines. One is pellet feed machine, which is used for fodder. Pellet feed machine usually is small pellet mill. The other is wood pellet machine, whi

ch is used for biomass fuel particles.

Due to the difference of mould, pellet mill is divided into two types: flat die type and ring die type. For flat die type, the die sits flat and rotates all the time during work time. For ring die type, The direction of the mold is vertical. When it works, the die is static, while pressure rollers is rotated instead of mold. In comparison, ring die type is more effective because materials can be centrifuged and evenly distributed.

The type which our company produces is ring die pellet machine.

The four procedures of wood pellet production line

Turning wastes into particles is an complex process. It consists of crushing, drying, pelletizing, cooling and packing. Except from pellet machine, we also need to prepare something else, such as wood crusher, dust collectors, belt conveyors, hot air stove, dryer, induced draft fan, bag filter, silo, skip hoist, distribution platform, cooler, baler and so on.  So do you know how to make pellet fuel?

four procedures of how pellet mill works
four procedures of how pellet mill works

First of all, make sure that materials is desirable. Its diameter should be less than five millimeters and the moisture content is less than 8%. If not, put them into drum chipper to make them smaller, then put raw materials into wood crusher. That’s the crushing procedures.

Now raw materials become powder. After removing dust, they are transmitted to the dryer by belt conveyors. With the help of hot air stove and induced draft fan, the temperature inside the dryer becomes extremely high and when materials go through it,  the procedure of drying is finished.

Next, materials are sent to the silo by a conveyor, and then it climbs onto the distribution platform, which is above the pellet machine. Under the influence of gravity, materials are distributed to different machines. That’s the pelletizing process.

Several minutes later, particles get out of pellet mill. By flat conveyor, particles are going to enter into the cooler and prepare to be packed bag by bag.

The main equipment for pellet production

I will introduce some other main equipment: crusher, dryer and pellet machine.


Crusher is the equipment which is mainly used for processing branches, wood chips, waste wood, bamboo materials into powder during the pretreatment stage.

Usually the powder out of crusher should be less than five millimeters. Our company will provide you with eight types crushers, whose output ranges from 200~800k/h.

Model Powe(kw) Hammer slice(piece) Weight(kg) Dimension(L*W*H) Output(kg/h)

2. Dryer

Our company produces two kinds of dryers: air dryer and drum dryer. Drum dyer is more affordable for small pellet plant. Thus I’d like to introduce you some information about air dryer. Air dryer is heat flow pulse dryer, which is also known as hot air pipe dryer. Our air dryer includes several types: GQHG-400, GQHG-600 and GQHJ-800.

Model GQHG-400 GQHG-600 GQHJ-800 Remark
Evaporation capacity(kg/h) 180-300 300-500 400-600
Fuel consumption(kg/h) 30kg 40kg 50k Input moisture:20-40%
Output moisture:8-12%
Materials feeding quantity(mm) 3-5mm 3-5mm 3-5mm
Hot air temperature 180-250℃ 180-250℃ 180-250℃
Power (fan& airlocker) 4+0.75kw 5.5+0.75kw 6+0.75kw
Gross weight(kg) 1000kg 1200kg 1200kg
Overall dimension(L*W*H) 9*1.3*2.5m 12*1.3*2.5m 15*1.3*2.5m

This kind of dryer has the advantages of direct heating, quickly drying, folding installation and saving space. Air dryer is mainly composed of hot blast stove (the users should bring along their own), screw feeder, surge bin, duct, fan, cyclone dust collector etc. Hot air is mainly from oil burner, gas stove, coal-fired stove or steam heat exchanger. When it works, negative pressure generated by fan airflow, then materials enter into the air duct through the spiral feeder, meanwhile hot air get chance to mix with the material. Thus moisture has to be separated from materials with the help of cyclone dust collector, which reaches the effect of thoroughly drying. At last, waste hot water and steam come out from the top end of cyclone dust collector. The dying powder enters into next procedure.

3. Pellet machine

We have the most advanced electric vertical ring die pellet machine. By the way, we will customize a proper machine for you with the reasonable pellet making machine price.

It is consisted with inlet, discharge port, engine base, reduction gearbox, bearing room, motor, compression roller and ring die. Compared with diesel pellet mill, electric type is comparatively more environmental friendly. Compared with flat ring type, ring die type is more effective with a better molding rate.

When vertical ring die pellet machine is running, powders come down directly from the inlet. Under the rotation of pinch roller, wood powders spread evenly on the inner cavity of the mold. Going through high temperature and high pressure, wood powders extrude ring die’s small holes and become particles with particular size on account of different ring die.

In addition, theoretically there are three quick-wear parts. They are compression roller, the mould and screen cloth. So we suggest that you may as well purchase some spare parts to save time if the equipment happen to get into trouble unluckily.

Features of our pellet making machine

Although cheap pellet mill is everywhere, but price should not be the only factor when choosing pellet machine manufacturers. As a matter of fact, you need to find the most suitable one. Our pellet mill machine not only has the favorable price, but pays more attention to every detail.

1. It has beautiful appearance, small size, reasonable structure and good shaping effect. Such portable pellet mill is very popular in the market.

2. It adopts special forced feeder to ensure the unremitting feeding of raw material. In addition the motor of the feeder is variable-frequency and variable-speed motor.

3. The main drive adopts gear with high-precision to transmit. Compared with belt drive type, its production is increased more than twenty percent.

4. We adopts high-quality bearing and oil seal from abroad, which leads to effective and stable running and low noise.

5. In addition the motor of the feeder is variable-frequency and variable-speed motor.

6. Our coupling is serpentine steel flex coupling, which is close to international advanced level. It is unique, compact, safe and less noisy.

7. There are various ring die with different diameter for choosing. It can produce smooth pellet and get longer service life. Due to the difference of mould, pellet mill is divided into two types: the flat die type and ring die type. For ring die type, The direction of the mold is vertical. When it works, the die is static, while pressure rollers is rotated instead of mold. In comparison, ring die type is more effective because material can be centrifuged and evenly distributed.
