Brucite mineral processing grinding mill

Brucite is the mineral form of magnesium hydroxide, with the chemical formula Mg(OH)₂. It is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists; and formed during serpentinization of dunites. Brucite is often found in association with serpentine, calcite, aragonite, dolomite, magnesite, hydromagnesite, artinite, talc and chrysotile.
Brucite is used as a flame retardant because it thermally decomposes to release water in a similar way to aluminium hydroxide and mixtures of huntite and hydromagnesite. It also constitutes a significant source of magnesium for industry.
Brucite has white color, easy to split, high rate of velvet. Because it’s unique and excellent performance and low price, brucite become the first choice of today's asbestos natural substitutes. At the same time, as a reinforcing, reinforcing materials and additives for domestic and foreign production asbestos cement, rubber, brake, friction, sealing, insulation, paint, textile, adsorbents, flame retardants and other products brought good opportunities.

Detailed Product Description about Brucite mineral processing grinding mill
Brucite mineral processing 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, Brucite mineral processing 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)
Input Brucite ore size: ≤20mm

Working Principle of Brucite mineral processing 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 materials 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.

Production Line Configuration of Brucite grinding mil:
crushing machine, 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.

Features of Brucite mineral processing grinding mill:
1. High efficiency
At the status of the same finish fineness and power, its production capacity per hour is twice as much as other jet mill, mixing grinder and ball mill.
2. Long lifecycle of wearing parts
The ring and rollers are forged by special material with high utilization. Under same grinding material and finish fineness, the wearing parts life cycle usually is one year, which is 2-3 times longer than impact mill and turbo mill. The service time can reach 2-5 years if grinding carbonate (calcium carbonate).
3. High safety and reliability
There are no rolling bearings and bolts in grinding cavity, so there are no problems caused by bolts shedding or wear of bearings and seal components.
4. High fineness and flexible adjustment
The final product fineness can be adjusted between 325 meshes and 2500 meshes (47 microns to 5 microns), and the product fineness can reach D97≤5μm.
5. Environment friendly
The application of pulse deduster and muffler alleviate the dust pollution and noise.
