The CMS Pin Mill is an excellent grinding mill option when your production targets call for particle sizes at medium fineness |> 35 µm D90 |.

How Does a Pin Mill Work?

The pin mill incorporates a design configuration combining pins mounted to a stationary disc plate and a second rotational rotor plate. Material (via air) passes through the

grinding zone, where centrifugal force accelerates the production materials through intermeshing shearing pins then impacting the liner wall. Processed 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 cut points without the need for mill shutdown. The milling process will produce particle sizes down to ultra-fine micronized sizes +/- 10 µm. Particle sizing generated by the pin mill is the product of rotor tip speed, airflow rate, the feed rate of the material to be processed, and the morphology of the feed material.

The CMS Pin Mill series is available in models up to 150 HP.

Classifier Milling Systems pin mill incorporates a hinged mill cover for easy access to components and wear parts and for quick and easy cleaning. Additionally, pin mills can include a blow-thru air system | up to 1000 cfm | which increases materials throughput and adds cooling of heat-sensitive materials.
