300-3000 mesh Mineral Powder process
300-3000 mesh Mineral Powder process needs HGM Micro Powder Grinding Mill, it is the new type mining equipment for making micro powders, fine powders，which is widely applied in the industries of metallurgy, mining, chemistry, cement, construction, refractory materials, ceramics, and so on.The purpose of the micro powder grinding millis for super-fine grinding materials with hardness less than 9 in Moh's scale and humidity less than 6 percent such as Barite, quartz, feldspar, mica, calcite, talc, apatite, gypsum, fluorite, limestone, dolomite, quartz stone, ceramic soil, clay, marble, granite, fly ash, kaolin, calcium carbonate, pebbles, coal, slag, bauxite, coal gangue, bentonite, iron ore, copper ore, basalt, pumice, diatomite, magnesite ore, manganeseore, potassium feldspar, refractory material, glass, total about 1000 kinds of materials.
Struction and working principle:
A whole powder grinding production line includes hammer crusher/jaw crusher, ultrafine mill, bucket elevator, hopper, screw feeder, grinder unit, in-built classifier, collector, pulse filter bag, discharging screw convey & valve, blower, muffler, air compressor, electrical control cabinet, sound-proof house.
For each parts, we will configurate different types and brand according to clients' practical needs.
Raw material was firstly crushed into small particles, and then sent to feeding hopper. With screw feeder, such particles will go into grinder unit and displaced on the upper turn-plate. Turn-plate is turning around the middle axis, and the grinder connects with reducer box, it is driven by the grinder motor. The powders will be grinded roller by roller, ring by ring, and fall down on the down turn-plate, and they will go through classifier with the airflow, as the high pressure produces negative wind. All the powder will be classified by the high speed turning classifier impeller. Qualified one will go into collector and filter bags. Big one will fall down and be grinded again. Most of the powders will fall into the collector, and few of them will go into bag house with the airflow. With the high pressure, the powder will fall down into screw conveyor and discharged from valve.
