This roller press can improve the grinding capacity by 50- compared to ball mill systems and reduce the power consumption of the grinding system by 30-40%, and 20-30% that of finished cement. The squeezed materials is easy to grind and 0.08mm fine material accounts for 30-30% and material smaller than 20 mm accounts for 65-85%.
Vertical roller mill machines are very important in the cement plant. Along with development of variable frequency drive controlling technology, nowadays mostly asynchronous motors are driven by variable frequency driver instead of old traditional technology such as soft starter to realize automatic control and changing cement production.
The cement industry is one of the most important and oldest industries in the world, with a history of more than 3,500 years. It is one of the most complex manufacturing industries with the largest number of processes in the manufacturing chain.
Cement Separator. Cement separator, also called cement mill separator, is the necessary equipment in the powder classifying system of cement, chemical, mineral, and other industries. It can respectively collect the qualified fine powder and coarse powder from the airflow after they are ground by the grinding equipment to a certain extent.

fault on Cement Mill 7 at the Cemex plant in Egypt, avoiding unplanned downtime that could have cost as much as US$510,000. If the faulty bearing had not been discovered in time, it might have seized up, causing an emergency shutdown of the mill. A two-day stoppage for repairs would have resulted in a product loss of 4600t at an average price

1. Damage of accumulator nitrogen airbag When the pressure of the grinding roller is not balanced, the buffering force of each pull rod is different; and when the pressure is too large, the buffering capacity of the nitrogen is reduced, and the vibration of the grinding machine is caused. The failure of the nitrogen bag can be found in time

Vertical Roller Mills When it comes to your VRM, you have certain expectations: reliable, consistent performance; expected capacity, and optimum energy efficiency. But realising those expectations is dependent on achieving the right operating parameters, the best mechanical settings and ensuring the good condition of critical components.
Roller Press is the most critical asset for cement plants as any unplanned shutdown can cause huge production loss. The vibration and shock caused by the bearing faults could endanger the running safety of the roller press.
In mineral processing, horizontal grinding mills must endure vibration, shock loads, moderate to slow speeds and a high concentration of particulates. In these conditions, contamination, loss of lubricant and even improper mounting techniques can all lead to failures for pinions or trunnions. And, of course, cause costly downtime and repairs ...
