What is a sawdust machine?

A sawdust machine is a mechanical device specially used for finely crushing wood, also known as a sawdust wood powder machine. Its main function is to process various wood, wood scraps, branches and forks, wood chips, board edges, bark, bamboo, bamboo skin and other raw materials into sawdust or wood fiber products. Sawdust machines have the advantages of low investment, low energy consumption, high productivity, good economic benefits, and convenient use and maintenance.

The working principle of the sawdust machine is mainly to efficiently process soft fiber materials through rotary cutting of the blade. In addition, the sawdust machine can also be used in the cultivation of edible fungi, the production of high-density boards, papermaking and other industries. Its wood chips are small in size, the wood fiber fibers are obvious, the discharge is uniform, the energy consumption is low, the output is high, the sawdust product quality is good, and the processing cost is low.

The sawdust machine processes wood, branches and other raw materials into fine sawdust through five steps: feeding, cutting, crushing, screening and discharging. First, the raw material enters the machine through the feed port, is initially cut by the high-speed rotating cutter disc or blade, and then enters the crushing chamber, where it is further crushed by the hammer or crushing knife. The crushed material is controlled by the screen to control the particle size, and the sawdust that meets the requirements is discharged through the fan or exhaust system, while the material that is not completely crushed is returned for further processing. Finally, the finely crushed sawdust is discharged from the discharge port.

The screen of the sawdust machine determines the fineness of the material

The particle size of the sawdust machine can also be adjusted according to customer needs. The fineness is mainly adjusted by the screen, which is stamped by steel plate. The screen is the main component that determines the particle size of the material produced by the equipment. The sawdust machine first cuts the wood chips with a blade and then crushes them with a hammer. After the rotor generates a high-speed airflow, the material is accelerated in the airflow. Repeated impacts cause the material to be affected by double extrusion. The material that reaches the screen size comes out of the screen hole, and the material that does not meet the standard continues to be crushed in the crushing chamber until it reaches the standard.

The sawdust machine is a mechanical equipment specially used to crush various waste wood materials. Now most of the waste wood is crushed by this sawdust machine, and then made into sawdust-like materials for reuse, which not only saves a lot of wood resources, but also avoids resource waste.

• Wood processing

Sawdust machines are mainly used in the wood processing industry, which can convert waste wood fragments into reusable particles and improve the utilization rate of wood resources. It is widely used in furniture manufacturing, paper industry and other fields to produce wood chip particles, wood chip boards, pulp raw materials and other products.

• Building materials

Sawdust can be used as part of building materials to produce plywood, compressed boards, plywood, core boards and other materials. These materials are widely used in decoration and furniture, greatly improving the utilization rate of wood and reducing waste.

• Biomass energy

Sawdust machines are also widely used in the biomass energy industry. Sawdust can be used as a raw material for the production of biomass particles and used to make biomass energy. This energy is not only environmentally friendly, but also has a high calorific value. It is an ideal renewable energy source.

• Farming industry

Sawdust can be used for floor laying in farms (such as chicken houses, pig houses, and cattle houses) to absorb moisture, keep dry, and reduce odor. Some wood chips can be used as fiber additives in feed (subject to safety standards).

• Agriculture

Sawdust can be mixed with livestock and poultry manure and crop straw for fermentation to make organic fertilizer. Sawdust is also an important culture medium material for edible fungi (such as shiitake mushrooms and fungus).
