Ultra Fine Mill Advantages than Raymond Mills

Compare with the Raymond mill, ultra fine mill is one of the new technology powder making machines, and it’s often be used in superfine stone powder grinding. Ultra fine mill also have lots of names, such as: superfine powder mill, micro powder grinding mill and so on. It’s especially good at 300 mesh to 2500 mesh fineness powder grinding, and the capacity of ultra fine mill usually can up to 8-15 t/h.

As for the working principle of ultra fine mill, when the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grind by the rollers.

Advantages of ultra fine 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 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.
