With the development of high-tech industry, micro powder is widely applied in various fields, and the demand for micro powder is ever-increasing. Daily used soaps, toothpastes, cosmetics, plastic films, PVC, rubbers, glass, fire retardants, high hardness grinding materials, building materials, chemicals, etc are closely related with micro powder.
The Dingbo three-ring micropower mill is for super-fine grinding materials with hardness less than 6 in Moh's scal and humidity less than 6% such as kaolins, limestones, calcite, marbles, barites, gypsums, pyrophyllites, dolomites, calcium carbonates, pigments, clays, coals, activated carbons, feldspar, talcs, mica, carbon black, petroleum coke, alumina, chromic oxide, quartz, cements, up to 100 materials.
Performance and features of Magnesite Grinding Mill:
1.High efficiency
Under the same final size and power, the product capacity of ultrafine 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 5micron.
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.
The fineness of for magnesite Powder Powder can be controlled between 325~2500 mesh /47-5micron.
