) was modified to estimate the specific grinding energy consumption of vertical roller mills. 2. Methods and results2.1. Pilot scale grinding tests. The grinding tests were performed with the pilot scale vertical roller mill located in the Loesche Test Center. The LM 3,6 type mill has 2 rollers and a nominal capacity of 707 kg/h.
As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.

Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor
of the raw material [1, 2]. For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated Using G K * D 2.51 Where, G is capacity of the mill, K1 is roller mill coefficient and D is table ...
