Ring Die Wood Pellet Mill

Ring die wood pellet mill vertical type wood pelletizer

This is a vertical type ring die wood pellet mill which can make biomass fuel pellets from wood material such as wood logs, tree branches, wood residues, wasted wood, wood chips, sawdust, and other biomass material like: EFB, bagasse, straw, agricultural stalk, rice husk, coconut shell, corn cob., etc

This pellet mill can pellet the raw material to 6mm, 8mm, 10mm, 12mm diameter biomas pellet with 600-700kh/m³ bulk density and 4000-5500 kcal heating value, the biomass pellets or wood pellets produced from this pelletizer can be used as fuel for boiler, home heating, power plants it also can be used as bedding for animals. Usually, people make high compression ratio wood pellets used as fuel to burn them, due to the high compression the wood pellets are hard with high density and when burning them there is a large heating value released. Some people make low compression ratio wood pellets used as animal bedding, These kinds of pellets can be matting on the floor of the animal house, due to the low compression so the pellets are not tightened and it can absorb the water and brine in the animal house so that to make it easy to clean animal house.

The raw material put into this vertical ring die wood pellet mill should be meet the requirement: the size of raw material smaller than the diameter of pellets will be made, usually make 6mm diameter pellets the size of raw material will be 3-5mm if make 8mm diameter pellets the raw material size should <7mm, if make 10mm diameter wood pellets the raw material size <8mm; best moisture of raw material to make wood pellets is 12-15%, the maximum moisture content moisture can intake is 17%, if moisture higher than this can not make good quality wood pellets or even can mot make pellets. So, according to this if your raw material size bigger than 5mm, you need equipment to crush the material before press pellets, if the moisture of your raw material is higher than 15% need a dryer to drying them before making pellets.

Technical data of ring die wood pellet mill：

Vertical type ring dies wood pellet mill is a kind of ring die wood pelletizer because the machine structure is a vertical type designed.

Raw material intake from the top of pellet mill, by gravity raw material, fall into pelleting chamber directly, inside the pelleting chamber the roller is rotating together with the 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.

This vertical ring dies pellet mill has the advantage to produce high-quality wood pellets and biomass fuel pellets from different kinds of wood material and biomass materials.

Advantage of our MKLH vertical type ring die wood pellet mill:

1. Vertical structure, the material can fall into the pelleting chamber by gravity, avoid material block in feeding part, easy to feeding material;

2. Vertical structure, easy to open the cover to for maintenance and change ring die and rollers, save time on machine maintenance;
   

3. When the machine running, the rollers are rotating while the ring die is stable, with the rollers running the centrifugal force can force the material to go to the hole of the ring die, improve pelleting efficiency;

4. The gearbox of our vertical ring dies pellet mill is brand name gearbox which is strong enough to make wood pellets, the gears and special designed structure can bring more powerful pressure compared than commonly used industrial gearbox, the motor is horizontally installed which connect to the gearbox by coupling so that to improve efficiency and stability.

5.Equipped with automatic lubricator, which can set interval time and grease inject time, thus to inject grease for bearings of roller and main shaft automatically so that to save labor and time on maintenance and improve production efficiency;

6.Double-layer ring die, when the holes one side is worn out can turn ring die to use the holes on the other side, thus to extend the lifetime of ring die and reduce cost on produce pellets.

7.Pellet mill equipped dust collector to collect dust and vapor from the pelleting chamber;

8.We can calculate the compression ratio of ring die according to your raw material, thus producing better quality pellets;

9.Equipped with electric panel apply soft start so that to reduce starting amps.
