The vertical roller mill is widely used in the mining industry, there are many advantages of vertical roller mill, So it’s welcomed by many customers.
 
l、 High efficiency
Under the same finished final size and the same motor power, the capacity of stone micronizer is twice as much as jet mill, mixing grinder and ball mill.
2、Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3、High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4、 High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5、Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.

The disanvantage of veritacal roller mill is need a big space for the plant.But it’s not a problem if the customer have enough space of their workshop.
