What Is A Wood Powder Machine and How Does It Work?

Wood powder machines are generally used after wood crushers to grind sawdust, wood chips, and granules to form a fineness between 30 mesh and 325 mesh. The materials are extracted by a fan, and then the screening machine is used to control the fineness of the finished materials. The materials of different meshes are collected separately, and the unqualified materials are collected and processed. After processing, wood flour is mostly used in incense, chemical and papermaking industries.

The fineness of wood powder produced by wood powder machines can reach about 300 mesh. However, according to market surveys and actual customer usage, the general usage is between 60-100 mesh. This mesh can be said to be finer than the flour we usually eat. It is mostly used in chemical, building materials, medicine, breeding, mosquito coils, health care and other industries. As for how many meshes to process, it is also closely related to the raw materials of the wood grinder. If the raw materials are logs or branches, it is impossible to directly grind them into wood powder through the wood grinder. They must first be crushed by a crusher or a shredder, and the moisture content must be less than 30%. The size of the raw materials for the wood grinder must be less than 3mm.

• High-speed rotation and material impact:

The wood grinder drives the main shaft to rotate at high speed through the motor, generating high-intensity impact force, compression force, cutting force and friction force. These forces act on the crushed materials, such as wood, bamboo chips and other fibrous materials, to achieve fine grinding function.

• Multi-stage crushing process:

The blade and centrifugal knife combination inside the wood grinder performs multi-stage crushing. First, through coarse crushing and fine crushing, and then through centrifugal reciprocating crushing to achieve the required fineness.

• Airflow assistance:

During the crushing process, the high-speed airflow generated by the main machine not only helps accelerate the material, but also enhances the impact and cutting force between the material and the blade. The airflow also helps to separate the fine particles so that they can be collected, while the coarse particles continue to be further crushed in the crushing chamber.

Wood powder machine is widely used in chemical, building materials, medicine, health care, breeding, food, mosquito coil and other industries. Wood powder machine can efficiently crush these materials into fine powder to meet the needs of different fields.

Wood fiber materials: such as sawdust, wood chips, shavings, fruit shells, rice husks, etc.

Special materials: including bamboo powder, chestnut skin powder, elm powder, camphor powder, cypress powder, shrimp powder, star anise powder, pepper powder, chili powder, pepper powder, refined cotton, feathers, feather stems, straw, wheat bran, rice husk, sticky wood, potato grits, cassava, Chinese herbal medicine, fish meal, cakes, magnesium silicate trihydrate, etc.

Other fiber materials: such as bamboo powder, wood powder, fruit shells, Chinese herbal medicine, bark, leaves, wheat bran, taro, hemp, rice husks, corn cobs, orange stalks, starch, grains, shrimp skins, fish meal, seaweed, dehydrated vegetables, hawthorn, dried ginger, garlic slices, pumpkin powder, seasonings, jujubes, paper, circuit boards, plastics, chemical raw materials, marine products, mica, graphite, bentonite, perlite, distiller’s grains, furfural, cakes, charcoal, activated carbon, cellulose, potato residue, tea, hair, soybean meal, cotton, cowhide, sheepskin, plant roots, stems, leaves, flowers, fruits, various edible fungi, etc.

First, check whether the full set of equipment of the wood powder machine is complete and reasonably designed. The number of blades, rotors, screens, dust removal equipment, motors and other parts need to be checked to see if the quality is up to standard. Only in the future can the stable production capacity be maintained during the operation of the machine.

Secondly, test the machine to see if the output of the wood powder machine meets the required standards. In the process of communicating with the manufacturer, the output has always been a problem that everyone pays attention to. Usually, the appropriate plan is determined through constant communication and discussion with the manufacturer in the early stage. Generally, the output performance of the purchased equipment meets its own requirements. As long as the equipment is made by a regular manufacturer, its performance and output are guaranteed. This can be completely determined by the company’s shipments. Only stable shipments can explain the use effect of the machine.

Finally, it should be combined with your own needs and usage. Generally, the higher the fineness of the wood flour and the higher the output required, the cost of the machine will be relatively higher!
