Vertical Roller Mill Unique Advantages and Features
LUM series vertical roller mill with many advantages. Firstly, it uses the principles of abrasive layer grinding, eliminate grinding, ensure product whiteness. And the finished product size less than 2 mu m particle content of up to 70%, and 325 orders, low residue, but also suitable for sorting out from two times more fine grain size of the finished product, ensuring the quality of the finished product. In addition, the special design of the grinding curve roller sleeve and lining board makes the vertical roller mill can be a grinding to the required fineness, greatly improving the grinding efficiency, its capacity is 3-6 times than ordinary powder equipment.
- final products has little iron and the whiteness and purity are quite high;
- producing little dust and noise, this LUM vertical roller mill is quite environmental friendly;
- adopting control system, this machine can save the operation costs;
- with special design of roller shell and grinding plate curve, this machine has excellent grinding efficiency.
Vertical Roller Mill Operation
The main structure of vertical roller mill is separator, grinding roll device, the grinding disc device, a pressure device, reducer, motor, shell and other components.
The motor drives the disc through the speed reducer to rotate, and the hot air from the air inlet into the vertical mill, the material from the feed opening falls on the disc center, due to the centrifugal force, the material is moved from the center to the edge of the grinding disc disc, the disc by an annular groove, by grinding roller rolling crushing, crushed material continues to move to the edge of the grinding disc, until the wind ring away, and the large particles and fall into the disc to crush.
In a flow of materials through the upper part of the separator, guide blades under the action of the cone bucket fell, crude material from a disc, a fine powder with air toghter grinding, dust collector is the collection, the powder is collected is the vertical mill of a product. The material is in contact with the shell in the process of drying gas, achieve humidity dry products required. By adjusting the separator guide blade angle (small vertical mill is not adjustable) and separator rotor speed, can achieve the required thickness of products.
