Horizontal Ring Die Pellet Mill is also named pellet machine, pellet maker, pellet press, pelletizer, pellet making machine and pellet mill. Which is main machine in wood pellet line. it is retrofit over products according to the characteristics of biomass fuel particles based on our feed pellet machine, it mainly used for pressing flammable biomass materials such as sawdust from soft wood and hard wood, wood chips, wood shavings, straw, stalk, grass, rice husk, bagasse, peanut shell, sunflower husk, coconut shell, EFB, and any other biomass material to pellets, so it is the most popular and most utility pellet mill among the three kind pellet machines.

Horizontal ring die pellet mill structure

Feeder auger.jpg

Ring die pellet mill is made up of base frame, motor, coupling, gearbox, main shaft, hollow shaft, rollers, ring die, force feeding system, feeding system, and control system.

1. The feeding system is the feeder auger on top of pellet mill, it adopt frequency control to change the feeding speed by VFD, thus to avoid material block in the pellet mill and overload, from the feeder auger, raw material go to force feeder by gravity.

2. The force feeder push the raw material go to pelletizing room, force feeder is important part in horizontal ring die pellet mill even it is a small part, because the bulk density of biomass material is low, the mobilityis not good, so the force feeder can help to prush the material into pelletizing chamber.

3. In pelletizing room of horizontal ring die pellet mill, there is feeder scraper, rollers, ring die, main shaft and hollow shaft, the rollers are fixed on main shaft which is stable during machine working, but the roller shell is running, the ring die is fixed on the hollow shaft by hoop, the ring die is running during machine working. After material go to pelletizing room, the rollers and scraper will press the material into holes on ring die, the material will press out from the holes to get pellets. The diameter and effective extrusion length of the holes decide the size of final pellets, the ratio between effective extrusion length of hole on ring die and diameter of the hole is called compression ratio, which is an important data of the ring die, it decide the quality of final pellets. According to character of different raw material, we can make special compression ratio ring die for one kind raw material, so just change the ring die can make the pellet mill suitable for different raw material.

Pelletizing room of horizontal ring die pellet mill

4. The main shaft is inside of hollow shaft, the back side of main shaft goes to sfety base, in case there is block in the machine but did not stop the machine in time, the safety pin will broken and give signal to control panel to stop the machine. In front of main shart there is the rollers.

In front of the hollow shat there is ring die, it is running during the machine is operating.

The rollers and ring die made up the pelletizing chamber, material feeded into pelletizing chamber, the rollers will press the material into ring die to compress pellets.

The ring die, rollers, main shaft, hollow shaft is installed in the pelletizing room in a horizontal level, that is why it is called horizontal pellet mill.

Why choose horizontal ring die pellet mill

1. Have feeding auger and force feeder, assure the machine suitable many different kind of raw material with both low bulk density and high bulk density.

2. Electric panel use VFD control the rotating speed of feeding auger and force feeder to control the feeding speed, thus to reduce the material block in pelletizing room. Electric panel have electromotor integrative protector to protect the motors in case of overload.

3. In case the pelletizing room is blocked, the door of pelletizing room is easy to open and clean.

5. Ring die lifter, make the work to change ring die far more easy.

6. At back side of main shaft can connect automatic grease lubricator, which can add grease to roller bearings and main shaft bearing automatically, thus can save labor.

7. Equipped with pellet cutter to adjust size of pellets.

Usage of final pellets

Pellets produced from biomass material are widely used for boilers, furnace, home heating, powerplants, nowadays it is also used for animal bedding.
