The CLM series classifier mills are a combination of two stages of closed-circuit grinding and air classification all in one unit. Materials that are difficult to grind and those that require a finer grind and/or a narrower particle distribution curve than is practical to produce in a fine grinder often require the capabilities of the CLM classifier mill. The built-in classifier, to separate part of the grinding rotor designed especially to handle these more difficult items to grind, rejects large particles not completely ground in the first stage of this grinder. They are reground and then reclassified.
