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.
Grinding and separation efficiency of vertical roller mill were evaluated. In addition to these, performance figures of vertical roller mill and conventional closed ball mill circuit were compared....
There is no doubt that vertical roller mills offer significant advantages over ball mills in terms of their energy efficiency. The specific energy consumption of a ball mill is greater than a vertical roller mill (VRM) that performs the same operations by a factor of between 1.5 and 2, depending on the degree of optimization of the ball mill.
