Building material market is booming with urbanization development, and that also leads to the development of vertical roller mill. Vertical roller mill, as a kind of high-efficiency energy-saving environment protection equipment, is more and more popular with more customers and has gradually replaced traditional ball mill. 

Study proves that high quality mill and correct operation is key to prolong the service lifespan of vertical roller mill, also to increase its grinding efficiency. So, how to prolong its service lifespan? 

Firstly, material hardness and content is important.  

Different materials with different hardness and contents will cause different abrasions of grinding roller, grinding table, and liners, therefore, appropriate selection of material can effectively increase the service lifespan of vertical roller mill. 

Second, material feeding status is also important. 

Feeding evenly is an important factor to guarantee normal operation of vertical roller mill, if there is no configuration of feeding equipment for production line, there will be plugging material. Uneven feeding will press much pressure on grinding roller, and cause abrasion directly, thus reducing service lifespan of mill. 

Finally, it is technicians’ correct operation and maintenance. 

Generally speaking, if the worker do not know about the machine, it is difficult to operate and maintain it, and this will cause the low production efficiency. Therefore, there must be professional and technical personnel to operate it, to perform correct sequence. When starting it, he should first start the blower, then start the main machine. When stopping it, he should first stop the main machine, then stop the blower. A series of problem including electrical short circuit, will be caused if the operator does not obey the correct sequence.

Vertical mill equipment is efficient or not is fundamental to production benefit, therefore, vertical roller mill is pivotal in an engineering project. To choose a good vertical roller mill means to choose a good start. 

CHAENG (Xinxiang Great Wall Machinery) has been dedicated to manufacturing vertical mill for more than 50 years, including Research & Development, manufacturing, sales and service, and pays much attention to improve mill quality and meet customers’ requirements. The grinding roller, grinding table and liners, with long-term contact with feeding material, are main wearing parts. The vertical roller mill manufacturers pays special attention to improve wear resistance to improve lifespan of vertical will, the Great Wall Machinery has great superiority in this respect with its large cast steel base, large machining workshop, electric control workshop, thus ensures qualified large parts of mill. This can not only ensure the production quality, production process but also solve vertical mill repair problem.
