Under what circumstances will the output of LM vertical roller mill fail to meet the design requirements?  Unreasonable design of length proportion of each bin of LM vertical roller mill unreasonable length proportion of each bin of LM vertical roller mill will cause imbalance of coarse and fine grinding capacity of LM vertical roller mill, resulting in excessive coarse or fine fineness of products, and then affect the output.  Generally, the length ratio of each warehouse of LM vertical roller 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. Note: the data are for reference only, and the specific equipment warehouse length ratio shall be subject to the design of the manufacturer.
