Powder Mill
2013 Dolomite powder mill in China
Dolomite powder mill, which is designed by our engineers and technicians on the basis of multiple innovation, test and experience over two decades, has absorbed many advantages of home and abroad mill manufacturing technique. It has been proved by thousands of customers that our machine has outstanding features and stable quality. Our Dolomite powder mill can upgrade its production and the additional value which is suitable for our customer to use. It is the ideal equipment for fine milling.
All kinds of quality dolomite series products: dolomite ore, dolomite sand 6-10 item, ten to twenty item, twenty - item, forty - 80 mesh, 80 -, - 120 mesh, dolomite powder 10 orders through, dolomite superfine powder 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry and agriculture, environmental protection, energy saving, etc. Mainly used for basic refractory and blast furnace ironmaking of fusing agent; Production of calcium magnesium phosphate and preparing magnesium sulfate; As well as the production of glass and ceramic ingredients.
Features of Dolomite powder mill:
1. High efficiency
Under the same final size and power, the product capacity of powder mill is twice than jet mill and agitation mill.
2. Longer lifetime of spare parts
The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 2-5 years.
3. High safety and reliability:
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4. High fineness of products
The product fineness can reach D97≤5μm.
5. Environment friendly
The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
Production Line Configuration of Dolomite powder mill:
The whole set powder mill consists of:
1). Hammer crusher, bucket elevator, storage hopper, vibrating feeder,
2). Main unit, inverter classifier, cyclone collector, pulse deduster system,
3). High pressure positive blower, air compressors and electrical control systems.
Working Principle of Dolomite powder mill:
●The crusher will crush the big materials into small ones, and then the elevator will send them to the hopper.
●The vibrating feeder will send the materials to the middle of first dial evenly.
●The motor of main equipment drives the main shaft and dial through reducer, and the dial drives numbers of rollers moving in the ring channels via pins.
●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 bring the crushed materials to classifier.
●The rotating turbo in the powder collector will make the coarse materials return to the mill and regrounded, 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.
