Emerald micro powder grinding mill

Emerald micro powder grinding mill industries in Zambia
Emerald is a variety of the mineral beryl colored green by traces amounts of chromium and sometimes vanadium. The emerald deposits of Zambia in the Kafubu River, about 45 km southwest of Kitwe, produced around 20% of world production of gem quality emeralds.
According to one legend, in the middle ages, the emerald ground into powder, used to stop bleeding, treat eye diseases and trauma. Today, with the development of technology, emerald can be processed into micro powder for multiple uses, like Decoration, cosmetics, medicine, etc.
Mass production of Emerald micro powder has been a trend, so emerald micro powder grinding mills industries are increasingly emerging, especially in Zambia.

Detailed Product Description about Emerald micro powder grinding mill
Emerald micro powder grinding mill is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 300~3000 mesh (47~5 micron) 
Comparable with ball mill, Emerald micro powder grinding mill has features of low cost, high capacity, easy operation; Comparable with Raymond mill for coarse powder up to 325 meshes, it can produce fine powders between 47 and 5 microns (300 to 3000 meshes)
Production Line Configuration of Emerald micro powder grinding mill:
The whole set HGM Emerald micro powder grinding mill consists of  hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems
 Working Principle of Emerald micro powder grinding mill:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse powder return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
