Determine the optimum moisture range of feeding materials of the vertical roller mill is an important measure to improve grinding efficiency, the range will be subject to each of the following factors.

When the material flowability is good, the water content of the material can be raised appropriately . After adding fly ash to slag, with the increase of flowability, the requirement of slag water content can be slightly broadened.

When the material is stored for too long, even though the same moisture content, but more grinding paste. Some ten years old tailings storage will grinding paste, even if the water is reach 0.8% paste

The smaller of the castor opening in Mill diaphragm partition, the more easily blocked, and An appropriate increase in the moisture content of the material by increasing the castor opening,

With a large amount and high speed wind,or the high temperature in the mill, the water content of the material could be increase correspondingly

In a word, company should find the Optimum moisture range according to the mill type, material, grinding process, and control it in the range.
