Therefore, ensuring that the output of silica sand mill meets the standard is the top priority it is a very common problem that the output of silica sand mill fails to meet the design requirements in the production of concentrator.  Under what circumstances will the output of silica sand mill fail to meet the design requirements? 1.  The unreasonable design of the length proportion of each silo of silica sand mill will cause the imbalance of the coarse and fine grinding capacity of silica sand mill, resulting in the phenomenon of too coarse or too fine fineness of products, and then affect the output.  Under normal circumstances, the length ratio of each warehouse of silica sand mill is as follows: warehouse number, warehouse type, 1 warehouse, 2 warehouse, 3 warehouse, single compartment 30 ~ 4060 ~ 70, double compartment 25 ~ 3025 ~ 3045 ~ 50.
