Roller mills may have from one to five rolls that grind pigments into vehicles most coating manufacturing facilities that use roller mills operate with conventional three-roll mills roller mills are labor intensive requiring highly skilled operators their lack of speed and high operating cost make them unsuitable for large-volume production.
Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling however by far the most important factor for fine grinding is media size and therefore the breakage rate small media has a larger surface area which translates to better transfer of energy.
Dec 18 2013&0183;&32;fine grinding to p80 sizes as low as 7 m is becoming increasingly important as mines treat ores with smaller liberation sizes this grinding is typically done using stirred mills such as the isamill or stirred media detritor while fine grinding consumes less energy than primary grinding it can still account for a substantial part of a mills energy budget.
