Ring die pellet mill

Biomass pellet mills generally have two types. One is called a ring die pellet mill while the other is called a flat die pellet mill. Both vary in their design, working principle, production capacity, etc. however, both have the same function - biomass pellets production.

Ring die pellet mill is the key component in a complete biomass pellet plant. It is mostly used to process wood materials like wood chips, sawdust, tree branches, logs, and so on, so it is a kind of large scale wood pellet maker. Also, it can process other raw materials like palm fiber, sugarcane bagasse, peanut shell, corn stalk, wheat straw and many other agro-wastes.

Ring die pellet machine is usually used when you need a biomass pellet mill for large scale production. As it is used for large scale production of pellets, its price is higher than other type of pellet mill. The capacity of ring die pellet mill can be 500~2000kg/h.

Working Principle of Ring Die Biomass Pellet Mill

A ring die pellet mill consists of several parts such as feeder, ring dies, rollers, motor, and discharge port. Raw material is fed into the pellet mill through a screw feeder from there it enters into the conditioner. In this part, an adherer, which helps in binding the particles together, is added and mixed with the raw material. It helps in forming dense and solid pellets.

From the conditioner, the raw material enters in the pelletizing region. This region has a ring-shaped die, thus this biomass pellet manufacturing equipment is called a ring die pellet mill. Two to four rollers are present inside the ring die. When raw material enters this chamber, centrifugal force pushes it on the inner side of the ring die. Usually, both roller and ring die rotate which presses the raw material in between two surfaces (one is of the roller and the other is of ring die).

Compressed raw material squeezes out of the holes of the ring die. When they come out of these holes they look like sticks. A knife-like slicer cuts these sticks and produces pellets of the desired size. Through it, you can change the length of pellets as per your needs. This is working process of a ring die pellet machine.

  • Larger Output: The production capacity of ring die pellet mill is relatively large and is more suitable for industrial pellet production
  • Superior Pelletizing Capability: It can process very wide range of biomass materials, especially the hard wood materials, like palm fiber.
  • Higher Quality Pellets: The pellets made by ring die pelletizing machine have larger density and is much smoother surface due to its higher pressure.
