Vertical Ring Die Pellet Plant

Vertical Ring Die Pellet Plant

Vertical ring dies pellet plant is used vertical ring die pellet mill is the main machine in pelletizing part, together with hammer mill, biomass drying machine, pellet cooler and pellet packing machine to make up a pellet production plant.

The vertical ring dies pellet plant can produce biofuel pellets from wood, straw, grass, corn cobs, sunflower husk, rice husk, coconut shell, peanut shell., etc biomass material.

Normally vertical ring dies pellet plants includes the material grinding part, material drying part, pelletizing part, pellet cooling part, and packing part.

--The purpose of the grinding part is to prepare the raw material, grinding the raw material to <5mm size, because to make biofuel pellets before material feed into pellet mill the size of raw material <5mm is the best. In this part according to the feature of different kinds of raw material we choose different machines to griding different raw material. The wood chipper, hammer mill, or wood crusher is widely used for grinding the raw material.

--Biomass drying part, the purpose is to dry the moisture of biomass material to 12-15% before it feeds into the pellet mill. Rotary dryer and flash dryer are two kinds of biomass drying machines, if the capacity is <1t/h and raw material initial moisture is <40% can use a flash dryer, otherwise the rotary drum dryer is the best choice.

--Pelletizing part, in this part the <5mm size dried biomass material will be compressed to biofuel pellets, the compressing process is called pelletizing.

The vertical ring die pellet mill has its unique advantages and it is one of the most popular pellet mills to make biofuel pellets.

The structure of the vertical ring die pellet mill makes it easier to feed biomass material into pelletizing chamber, and the duplex side ring dies greatly expands the lifetime of the ring die.

-- The cooling part and packing part are the same as the horizontal ring die pellet line, for any kind of biofuel pellet line, the cooling part and packing part is the same, use counterflow pellet cooler and pellet packing machine.

Vertical ring die pellet plant features:

1. Complete pellet plant to produce wood pellets and another kind of biofuel pellets, suitable for different kinds of biomass material

2. The vertical ring die pellet mill easier to operate and maintenance

3. Lifetime of ring die is longer

4. Vertical structure, rollers running while ring die is stable, reduce the pressure to the main shaft, thus improving the efficiency

5. We can design the plant according to features of raw material

6. We have vertical ring die pellet plant with different kind of capacity, such as: 800-1000kg/h, 1000-1500kg/h, 1500-2000kg/h, 2000-3000kg/h and 4000-5000kg/h.
