In some situations, roller mills use 85% less energy to process grain than hammer mills. In the most common processing situations, though, the energy savings are likely 3050%. This helps offset the initially high cost of a roller mill. Roller mills produce particles that are very consistent in size, though they are likely to be elongated ...

Industrial grinders, of the sort used to produce espresso pods or supermarket packs of preground coffee, are more or less exclusively roller mills. The most sophisticated of these grinders can grind coffee without significantly heating the grounds, and in the process produce very narrow particle size distributions with minimal fines. This makes roller mills ideal for grinding coffee, except ...

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
