Description of Ultra Fine Grinder:
This WFJ Super Fine Grinder is widely used in chemistry, dyestuff, dope, pharmaceutical, foodstuff industries. The grinding, classifying and production are processed in one obturating system. No pollution after dedust.
It is the complete set for sanitation and safety, also for heat sensitive and sticky material.
Air classifier mill material would be conveyed by feeding system evenly to milling chamber, and would be impacted by high-speed rotating beater, and also under the centrifugal force, it would impact the grinding track. By several different pulverization powers, the material would be milled into fine powder. The milled powder would go with air flow up to the classifying chamber. With the help of adjustable classifier wheel. coarse powder and fine powder would be separated. Qualified fine powder would be go through the wheel vane then into the cyclone separator or dust collector. while mixture of coarse powder and fine powder would fall down to the milling chamber to be milled again.
Application of ultra fine grinder:
Super fine grinder applies to the following seven non-metallic mineral hardness, diatomite, fluorspar, Fluorite, mica, and Low humidity, high melting point, viscosity of sulfur Juan, pesticides, and other ultra-fine grinding of Materials to solve the major problem which current domestic crushing industry can not solve. Fineness Can reach at 5 to 10 microns. Especially for cocoa coarse material, cocoa shell, coconut cake, rice, sugar, corn, fibre material, medicinal materials...
Features of ultra fine grinder:
1. In the machine chamber, there is the leaf structure. When operation, the air in the grinding chamber is blown out by the rotary leaves taking out the heat .
2.Therefore, there is no much heat in the chamber to ensure the characteristic of the material. When operation, the strong air flow can expel the material out. So it can pulverized the heat sensitive and sticky material with good effect.
3.For the food performance on the heat, it can be the substitute of universal crusher.
4. By the pull of the fan, the air flow in the grinding chamber blows the fine powder out(the fineness of the powder is adustable though the sieves). Thus, it can increase the capacity of the machine.
