Wood powder machine

Wood powder machine is used for lightweight materials, fiber materials, brittle materials, ductile material such as special grinding difficult milling equipment.

What is wood powder machine?

Wood powder machine is used for lightweight materials, fiber materials, brittle materials, ductile material such as special grinding difficult milling equipment. Crushing method of wood powder machine is divided into two kinds, namely horizontal hammer mill and vertical roller mill. Horizontal hammer wood powder machine including; standard wood powder machine, fine wood powder machine, ordinary wood powder machine, Chinese stainless steel wood powder machine, winnowing wood flour machine, water-cooled wood powder machine.

The roller type wood powder machine is composed of centrifugal grinding, impact crushing, shearing, crushing, impact crushing,  and crushing. It uses the principle of fluid mechanics to make sawdust, fiber, non-metallic mineral materials milling to less than 350 mesh. The utility model has the advantages of good performance, high efficiency, low abrasion, small occupation area, easy installation, easy operation, etc. The product has good particle size index and stable performance. The machine is widely applicable to the ultrafine grinding of non-mineral materials and non- inflammable and explosive materials with Mohs hardness below 6.


How to work?

Wood powder machine consists of three parts: body, middle body and lower body.

The grinding knife is composed of 7 knives, a knife and a centrifugal knife.

The utility model is composed of a blower, a powder collector and a dust collector.

The host crushing chamber with 7 type knife, a knife and a knife centrifugal, coarse grinding, fine grinding and centrifugal crushing action. The motor drives the pulverizer rotor to run at high speed, which causes the machine to produce high speed airflow, and has high impact force, compression force, cutting force and friction force on the crushing material to achieve the unique crushing function.

Cutting in three kinds of blades in the grinding process, the rotor produces high speed airflow with the blade rotation direction, the material in the air flow accelerated and repeated impact, friction and cutting, crushing effect by three. The crushed material is analyzed with the airflow into the analyzer, due to the centrifugal force acting on the analyzer rotor and the centripetal force of the air stream. So when the centrifugal force is greater than the centripetal force, the fine particles with the airflow enter into the powder collector collection of coarse particles into the crushing chamber to smash the centrifugal action until it reaches your satisfactory fineness.



1. High capacity. Compared with other roller mills, the output increases by 20~30% under the same power condition, and the grinding pressure of the grinding wheel material increases by 60~80% under the action of the high-pressure centrifugal force. The output of the grinding mill is increased by 150~300% than the hammer crusher.

2. Low energy consumption. When the yield and fineness indexes are the same, the energy consumption of sawdust is only about 1/3 of that of air mill.

3. Even particles. The fineness index of the product is good: when crushing sawdust, the fiber is good, and the smallest can reach 200~350.

4. Environmental protection. Equipped with stepless speed regulator of grading impeller, the particle size of the product can be adjusted without stopping the machine, and the fine powder can be recovered completely without polluting the environment.

5. The machine has the cooling function, when the grinding temperature is low, especially suitable for the processing of heat sensitive and fibrous materials, uniform product size.


For what?

Wood powder machine is suitable for: wood powder, bamboo powder, sawdust, chestnut peel powder, elm powder, wood grain, grain leather, camphor powder, shrimp powder, aniseed powder, pepper powder, chili powder, refined cotton, feather, feather stalk, straw, wheat bran, rice husk. Wood stick, potato slag, cassava, Chinese herbal medicine, fish meal, cake, grinding sanshui magnesium silicate and all fiber materials. It is an aquaculture industry wood crushing equipment used for bakelite, plastic, paper, incense, feed, Chinese herbal medicine.

The wood mill driven by the motor speed of the spindle, the machine can produce impact force, high strength of the crushed material compression force, cutting force, friction force, so the machine of material has a unique function of the crusher.
