Therefore, provision is made for controlled spray water inside the mill During mill operation magnetic separator and metal detector should be always functional to ensure to exclude tramp metal which can damage the grinding surfaces. Primary Vertical Roller Mill Controls are Mill drive power or mill differential pressure to control mill feed rate.Water spray is controlled with mill outlet gas or material temperature. A hardware interlock is recommended with mill main drive to avoid accidental spray in mill. Grinding aids are generally added to the ball mill to reduce electrostatic agglomeration of fine particles and to reduce coating formation on grinding media which reduces grinding efficiency. The optimum addition rate should be determined carefully to enhance grinding.
