Sawdust ring die pellet machine is a kind of equipment used to produce biomass pellet fuel. Its working principle is to convert biomass materials such as wood chips into solid pellet fuel through compression and high temperature treatment. Such equipment can be used not only to produce fuel, but also to produce animal feed and organic fertilizers. The sawdust ring die pellet machine has many advantages in the production process.

1. Its production efficiency is very high, and it can quickly convert a large amount of wood chips and other biomass materials into granular fuel.

2. Its production cost is lower, because biomass materials are usually cheaper than traditional fuels such as coal, and the production process does not generate a lot of waste and pollutants.

3. The sawdust ring die pellet machine also has good environmental protection performance, because no harmful gas and waste water will be produced during the production process, and the impact on the environment is very small.

(1) Product structure:

The vertical ring die wood pellet machine consists of a pellet machine base, a large reduction box, a bearing room, a feeding cover, a discharging part, and an electric motor.

Machine, pressure roller assembly, mold and other components.

(2) Working principle:

The sawdust pellet machine operates in the direct-connection mode of the motor. The motor is connected to the shaft of the reducer through a gear coupling. After a 90° change of direction, the horizontal motor drives the hollow transfer spindle of the vertical casting, and the spindle drives the pressure roller to roll the mold. The inner surface completes the pressing process.

When working, the raw material of biomass sawdust falls vertically from the feed inlet, and the material is continuously and evenly distributed on the surface of the inner cavity of the mold (the contact surface between the pressing roller and the mold) through the rotation of the pressing roller, and the powdery material is crushed by the pressing roller Holes through the mold (holes evenly distributed on the inner surface of the mold). In this process, the material is subjected to high pressure and high temperature, resulting in physical changes or appropriate chemical changes (according to the material), which promotes the powdery material to form a continuously elongated cylindrical solid body, and then the particles are cut off by a broken knife and discharged from the discharge port. The pressing process of the pellets is complete.
