Biomass Sawdust Wood Pellet Mill
Biomass sawdust wood pellet mill is a kind of ring die pellet mill, it is developed from ring die pellet mill, because the feeding structure is vertical type, so we call it vertical ring die pellet mill.
Raw material feeding from top of vertical pellet mill, by gravity raw material fall into pelletizing chamber directly, inside the pelletizing chamber the roller is rotating together with main shaft, while the ring die is stable, the rotating roller and the centrifugal force from running roller push raw material go to holes on ring die, under the pressure from running roller, the raw material compressed to pellets.
Our vertical pellet mill have advantages to produce wood pellets from sawdust, wood shavings, wood chips, woo logs, tree branches, waste wood, it can produce high quality wood pellets. But benefit by it’s vertical structure, it have much more advantages on soft material and low bulk density material compared with horizontal ring die pellet mill and flat die pellet mill.
For soft and low density material like straw, EFB, peanut shell, corn stalk, wheat stalk, sunflower husk, rice husk, because the density is low the mobility and gravity is low so is it much harder to feed into pelletizing chamber, if use horizontal ring die pellet mill produce pellets, material is easy block in the force feeder, if use flat die pellet mill to produce pellets the efficiency is low. If use vertical ring die pellet mill produce pellets the material is easy fall into pelletizing chamber directly, and the vertical pellet mill is roller rotating, the rotating rollers bring centrifugal force to force the material go to holes on ring die, thus the vertical ring die pellet mill is easier to handle soft and low bulk density material.
Advantage of MKLH biomass sawdust wood pellet mill
* Vertical structure, material can fall into pelletizing chamber, avoid material block in feeding part, easy feeding material
* Vertical structure, easy to open the cover to change ring die and rollers, save time on machine maintenance.
* When machine running, the rollers are rotating and ring die is stable, with the rollers running the centrifugal force can force material go to hole of ring die, improve pelletizing efficiency
* Solve the problem of make pellets from soft material and low bulk density material
* The gear box designed by our company is much bigger, the gears and special structure can bring more powerful pressure compared than commonly use industrial gear box, so our self-designed gear box is more suitable for pellet mill
*Equipped with oil cycle pump and oil cooling fan, to cycle and cooling the oil in gearbox, to improve the machine working stability
* Equipped with automatic grease pump, it can set interval time and grease inject time, thus to inject grease for bearings automatically, so that save labor and time on maintenance and improve production efficiency
* Double layer ring die, when one side is worn out can turn the ring die to use the other side, thus to extend the lifetime of ring die and reduce cost on produce pellets
* We can calculate compression ratio of ring die according to your raw material, thus to help produce better quality pellets.
The compression ratio of ring die is important for pelletizing, same pellet mill same raw material if the compression ratio of ring die is different the final pellets quality is different, so a suitable compression ratio for the raw material is essential. The compression ratio is decide by the effective compress length of the hole on ring die, this length decide the raw material compress time in the hole so it decide the hardness, color and quality of final pellets.
