Feed crusher machine is a special grinding and crushing equipment for light materials, fiber materials, brittle materials, tough materials, etc. It is the latest product developed by our factory. This machine improves the fineness of wood powder. Up to 10-1000 mesh, to solve the vacancy of ultra-fine powder on the market. At the same time, in the process of milling, two grade zones (ie general-grade zone and ultra-fine zone) can be separated. The equipment design is reasonable, low loss and low noise. , no pollution, easy to operate, once in the market, it has taken a leading position in the wood powder machine market.
Also known as the “high-fine grinding machine” in the market, the high-fine wood powder machine combines various pulverization principles at home and abroad, and is an energy-efficient wood powder grinding that integrates multiple pulverization principles. In addition, the machine is finely made and has a high processing technology. It adopts a double-layered body, and the tap water is injected into the body to perform water cooling. A new type of material is installed to provide sound insulation and heat dissipation. Therefore, the fiber grinding is used in production. Medium noise and no vibration. The high-fine wood powder machine is beautiful in appearance, sturdy and durable, and has high output. It is more than 50% more efficient than the traditional wood powder machine. It is an ideal milling equipment that cannot be replaced by any crushing equipment, filling the market gap.
The main machine crushing chamber adopts 7-knife, a type knife and a centrifugal knife. It is coarsely pulverized, finely pulverized and centrifuged to re-pulverize. The motor drives the grinding rotor to run at high speed, so that the high-speed airflow generated by the machine produces high-impact impact force on the pulverized material. , compression, cutting force, friction, to achieve a unique crushing function.
Fineness: 30--300 mesh can be adjusted arbitrarily. The yield and fineness vary according to the specific gravity of the material. The main machine motor can be large or small, depending on the material fineness output.
Working principle: The flow grinding and the cyclone separator, the dust collector and the induced draft fan form a complete set of pulverizing system. After the compressed air is filtered and dried, it is sprayed into the pulverizing chamber at high speed through the Laval nozzle. At the intersection of the multiple high-pressure air streams, the material is repeatedly collided, rubbed, sheared and pulverized, and the pulverized material rises under the action of the fan. The airflow moves to the grading zone, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating grading turbine. The fine granules meeting the particle size requirements are collected by the grading wheel into the cyclone separator and the dust collector, and the coarse particles are descended to the pulverizing zone to continue pulverizing.
