CLM Series Classifier Mills – Grinding and Air Classification
The Prater-Sterling CLM Series of classifier mills is a combination of two stages of closed circuit grinding and air classification all in one unit. This particular mill outperforms single-stage mills when handling difficult to grind products and those products requiring a narrow particle distribution. 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 unique capabilities of the CLM classifier mill. Oversized particles that are larger than specified are rejected by the classifier and are directed to a separate part of the grinding rotor where they are reground and then reclassified.
The large access door on these classifier mills allow for quick inspection and/or cleaning of the main rotor as well as the classifier rotor. In addition, the automatic door interlock prevents access to the mill internals during operation and prevents dangerous motion during access.
