Structure and design of sawdust briquette machine
Sawdust briquette machine is a kind of equipment that processes sawdust and other biomass raw materials into high-density solid fuel. Its structural design is scientific and reasonable, which can effectively improve production efficiency. The following will introduce its main structure and function from four aspects: feeding part, heating part, molding part and control system.

1. Feeding part
The feeding part of sawdust briquetting machine consists of hopper and internal spiral impeller. The hopper is designed as a cone-shaped structure, which is wide at the top and narrow at the bottom to ensure that raw materials can fall at a constant speed, thus avoiding the problem of blockage. The spiral impeller is located at the bottom of the hopper, which can push the falling raw materials forward and finally squeeze into the molding system. Users can choose manual feeding or automatic feeding through conveyor belt to meet different production requirements.
2. Heating part
The heating part is the core structure of sawdust briquette press, which is mainly composed of heating wire, heating sleeve and electrical components. The heating ring is sheathed on the outer surface of the forming cylinder, which can uniformly heat the sawdust passing through the forming cylinder and make it shape rapidly at high temperature and high pressure. It is worth noting that the heating ring, as a wearing part, has a limited service life, so users usually equip multiple sets of heating rings for replacement when purchasing equipment.
3. Molding part
The molding part is the key to realize the molding of raw materials by sawdust briquetting machine, which mainly includes molding cylinder and molding die. The forming cylinder can be designed into different shapes, such as quadrangle or hexagon, according to the requirements, so as to meet the diversified requirements of users for the shapes of biomass briquettes. When it is necessary to produce briquettes with different shapes, it is only necessary to replace the corresponding mold, which is convenient to operate.
4. Control system
Sawdust briquetting machine is usually equipped with PLC controller for automatic operation. PLC controller can accurately control the working state of equipment, including feeding speed, heating temperature and briquetting process, which greatly improves the stability and production efficiency of equipment operation.
Through scientific and reasonable structural design, the sawdust briquette machine has realized an efficient production process from raw material feeding, heating to molding. Its modular design is not only convenient for operation and maintenance, but also can be flexibly adjusted according to the needs of users, which is widely used in the field of biomass energy and provides important support for environmental protection and sustainable development.
