The CMS Pin Mill is an excellent grinding mill option when your production targets call for particle sizes at medium fineness | +/- 35 µm D90 |. The pin mill is designed for fine grinding of medium-hard feedstock materials (Moh’s Hardness of 4 or less).
The CMS Pin Mill incorporates a design configuration which combines pins mounted to a stationary disc plate and pins to a second rotational rotor plate. Material (via air) passes through the grinding zone, where centrifugal force accelerates the production materials through the pins, then impacting the liner wall (stator pins, smooth or ridged). Materials below the target cut point will exit the mill to a cone hopper, while material above the cut point recirculates for continued grinding. An inverter drive allows the operator to shift for desired particle sizes without the need for shutdown. The CMS Pin Mill is available in models up to 150 HP.
CMS Pin Mills also incorporate a hinged cover, providing easy access to mill components and wear parts and quick and easy cleaning. Additionally, the CMS Pin Mill can include a blow-thru air system | up to 1000 cfm |, which increases throughput and provides cooling of heat-sensitive materials.
