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.
