Introduction to Ring Die Wood Pellet Machine
This MKLH ring die pellet machine capacity ranges are from 500kg to 1500kg per hour. According to the characteristics of biomass fuel pelletizing, it is mainly designed for pressing combustible materials such as saw dust and grass into pellets. This pellet machine is usually equipped with 8mm and 10mm ring dies, because the 8mm and 10mm particle diameters are more favorable for combustion. Ring dies with other hole diameters can also be equipped according to different demands of users.

Main Characteristics of Ring Die Wood Pellet Mill

1. Driven by gear, so that the output is improved by about 20% when compared with that of belt drive.
2. Advanced bearing and oil seal are adopted to ensure efficient, stable and low-noise whole machine operation.
3. The feeder adopts variable-frequency and variable-speed motor to ensure the quality of discharged particles.
4. High-quality craft ring dies are adopted, so that the service life is long; the discharged pellets are smooth and the quality is high.
5. Snakelike spring coupling has the properties of novel and compact structure, low noise and low fault rate.

What Materials can be Pelletized by Ring Die Wood Pellet Machine?
Nearly all forestry and agro-waste material can be made into wood pellets by our ring die wood pellet machine, such as: Wood Chips, Shaving, Sawdust, Groundnut-shell, Sugarcane Biogases, Caster Shells/Stalk, Coffee Husk, Paddy Straw, Sunflower Stalk, Cotton Stalks, Tobacco Waste, Mustard Stalk, Jute Waste, Bamboo Dust, Tea Waste, Wheat Straw, Palm husk, Soybeans Husk, Coir Pitch Barks/Straws, Rice Husks etc. The final pellets can be used for industrial boilers and large power plants as well as home heating.

Best Choice for Mass Biomass Pellets Production
Ring Die biopellet machine  are identifiable by the circular “ring” shape of their extrusion die. Generally small wheels in the center of the ring ride on the die and force the raw material through the extrusion holes.  Compared with flat die pellet machine, ring die wood pellet machine has three main advantages: Firstly, it is highlighted with high efficiency and large capacity. Secondly, biomass pellets produced by ring die pellet mill are more solid and smooth. Thirdly, with its long service life and low-malfunction rate, it is really a cost-effective machine if you want to start medium or large size wood pellet plant for commercial use.
For these reasons we suggest new mill operators to start out with a flat die pellet machine while large industrial pellets production with ring die pellet machine.

Remark
The nature of raw materials fed to the biomass fuel pellet mill greatly influences the output, for example: the output of saw dust particles of hard wood is obviously lower than the output of saw dust particles of soft wood; the raw materials should not all be powdery. Containing some cellosilk substances, powdery materials are more favorable for particle forming.
