What Is The Structural Principle Of The Fuel Pellet Machine?
The fuel pellet machine is mainly composed of a frame, motor, reduction box, outer cover and feed hopper. A motor is installed in the lower part of the frame. The motor drives the transmission mechanism in the reduction box through a belt drive. There is a material receiving screen in the frame. There are discharge ports, reduction boxes, outer covers and feed hoppers on both sides. in the upper part of the rack. An outer ring sleeve is installed in the middle of the main shaft in the reduction box, and a rolled outer ring is mounted on the upper part of the outer ring sleeve. There is a fork fixed on the main shaft in the inner cavity of the rolled outer ring. On the fork, there are symmetrical It is equipped with two rolling toothed rollers and a material-picking paddle in the feed hopper.

When working, the straw raw materials are fed into the inner cavity of the outer rolling ring through the feeding hopper and the paddle. The straw raw materials are crushed by the rolling toothed roller and the outer rolling ring and squeezed out from the sieve holes around the outer rolling ring. Granular materials are formed. The utility model has a simple structure, is safe and convenient to operate, is applicable to collective or individual farmers, and has broad prospects for promotion. Simple operation and easy to use: high degree of automation, less labor, only 3 people are needed, manual feeding or automatic feeding by conveyor can be used.
The basic condition for the lignin in biomass to be able to bind together is a suitable molding temperature. By increasing the temperature, on the one hand, the lignin contained in the raw material can be softened, and on the other hand, the raw material itself can be easily compressed. Under natural water conditions, the softening temperature of lignin is 80 to 130 degrees Celsius. When heated to 70 to 100 degrees Celsius, the adhesive force of lignin begins to increase, and it can melt when the temperature reaches 160 to 250 degrees Celsius. Therefore, the heating temperature of biomass during molding must not be lower than its softening point temperature.
