Main purposes: Micro-mill is mainly applied to food(soybean meal, corn, rice, vegetable fiber, starch, food categories, dried small shrimps, fish meal, carrots, all kinds of dehydrated vegetables, flavors and fragrances, chitin), chemicals (dyes, pigments, paints, pesticides, white carbon black, carbon black, white carbon white, algal soil, bentonite, sulfur), pharmaceutical, food, tobacco, low calcium hardness of ultra-fine grinding of materials. Structure and Working Principle: The WFJ Grinder isa kind of vertical shaft reflection grinder, which can simultaneously complete the two working processesoffine grinding and fine powder separation . It is made up of such parts asthe main engine, the framework,the feeder, the grinding device, the material tube, the transmission device and the electrical device.The complete set is made up ofthe main engine, the dust remover, the high pressure centrifugal fan, the airlock, the tornado loading head, the electricity controlling cabinet, and the air current turbine wheel. The fineness of product can be freely adjusted without stopping working. And,the fineness of powder is stable,reaching 10-5um. This machine automatically cools itself.
