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 that of a vertical 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.
