The grinding concentration is high, and the materials are easy to be around the steel ball, which enhances the impact and grinding effect on the materials, but the pulp flow is slow, which is easy to cause over grinding.

In production practice, the grinding concentration is controlled by controlling the ore feeding amount of vertical roller mill, the replenishment amount of vertical roller mill, or adjusting and controlling the particle size composition and water content in graded return sand, so as to help improve the grinding efficiency of vertical roller mill.

Optimize the grinding process according to the ore properties of the raw ore (embedded particle size of useful minerals, monomer dissociation degree, embedded particle size of gangue minerals), such as pre tailing, pre enrichment, stage grinding and pre classification.
