Unreasonable grinding aid dosage vertical roller mill operation grinding can add a small amount of grinding aid without damaging the product performance, which can not only accelerate the crack propagation in material crushing, reduce the mutual adhesion between fine powders, effectively improve the grinding efficiency, but also improve the energy-saving efficiency of vertical roller mill operation.

However, vertical roller mill operation grinding aid shall be added according to the amount specified in the national standard.

Generally, in the process of cement production, the amount of grinding aid shall not exceed 1%. The proportion of grinding aid for other materials can be queried through the provisions of the national standard.

The above are the common problems that lead to the substandard output of vertical roller mill operation.
