Classification and characteristics of ultrafine pulverizer

　　The fundamental difference between the heavy-grinding ultrafine pulverizer and other forms of ultrafine pulverizer is that the speed of the heavy pressure grinding roller is slow (285R / min), while other mechanical ultra-fine pulverizer is high. Therefore, the wear of the heavy embossing parts is small and does not produce a lot of heat.

　　(2) Although the ultrafine pulverization mechanism of other forms of ultrafine pulverizer is mainly impact, shear, collision, break, etc., the ultra-fine pulverization mechanism is mainly through the drying wheel. Repeat loop is implemented. The ultrafine pulverizer utilizes air separation, heavy polishing, and shear, the ultrafine manner is used to achieve a dry material ultrafine pulverized apparatus. It consists of a cylindrical crushed chamber, a polishing wheel, a polishing rail, a fan, a material collection system, and the like. The material enters the cylindrical pulverizing chamber by the feed opening, and is crushed by the polishing wheel that is circumferential movement along the grinding rail, and dissensibly. The pulverized material brings out the pulverizer through the negative pressure air flow caused by the fan, into the material collection system, filtered through the filter bag, the air is discharged, the material, the dust is collected, and the pulverization is completed. The present invention also has the collision and impact mechanism of other forms of ultrafine pulverizer, but also has a mechanism of repeating extrusion abrasive, particularly suitable for high fiber content. Its air selection is just the final screening instead of cycling. (3) Compared with other forms of ultrafine pulverizer, the equipment is low, low equipment investment, small equipment. The workflow of the high-voltage ultramicrinder is: the feed port is a grinding, and the space division mechanism is a collector. 3. Crusher is also known as a low temperature crusher. The principle is to prepare material cooling and freezing in advance with liquid nitrogen below the embrittlement point, and the material is easily broken due to its low cryptress.
