High Efficiency Super Fine Bauxite Grinding Mill For Stone Powder Production Line
Description
【Material Introduction】
Bauxite, also known as bauxite or bauxite, is mainly composed of alumina, which is a hydrated alumina containing impurities and is an earth-like mineral. White or off-white, brownish-yellow or light red due to iron content. Hardness 1～3, opaque, brittle, extremely difficult to melt, insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. Mainly used for aluminum smelting, refractory products, abrasive materials, aerospace, communications, instrumentation, machinery, casting of medical equipment, etc.
【Applicable Materials】
Bauxite, kaolin, barite, fluorite, talc, water slag, lime calcium powder, wollastonite, gypsum, limestone, phosphate rock, marble, potassium feldspar, quartz sand, bentonite, manganese ore and other hardness Mohs 7 materials below grade.
HVM type vertical mill is a kind of safety, environmental protection, energy saving, high efficiency, which is designed and developed through painstaking research on the basis of widely absorbing the advanced technology of various vertical mills at home and abroad and drawing on a lot of engineering application experience. Advanced grinding equipment integrating drying, grinding, powder selection and conveying functions. The main performance and economic and technical indicators of the equipment have reached the international advanced level.

【Working Principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.
Product Advantages:
1. High efficiency and energy saving
High grinding efficiency and low energy consumption, compared with ball mills, energy consumption is 40%-50% lower; single machine production capacity is large
2. Easy maintenance and low operating cost
The maintenance operation is very convenient; the roller sleeve can be turned over for use, which prolongs the service life of the wear-resistant material; the high degree of automation is easy to operate and saves operating costs;
3. Low comprehensive investment cost
Simple process flow, less system equipment, compact structure and small footprint
4. Stable product quality
The product has uniform particle shape, narrow particle size distribution, good fluidity, strong product adaptability and stable product quality;
5. High reliability
The grinding roller limit device is adopted to avoid the violent vibration caused by the material cut off during the working time of the mill; the explosion suppression performance is excellent.
6. Environmental protection
low noise; the system is sealed as a whole, no dust overflow
