Ultrafine pin mill

Particularly designed for humid, oily, and greasy products.

Ultrafine pill mill proved to process even sticky materials in a wide chamber housing

The Contraplex Wide Chamber Mill – Contraplex CW from Hosokawa Alpine is an ultrafine pin mill, with two driven pin discs. Designed aiming to achieve high-power fineness values at a range of approximately 10 to 500 µm.

The fineness can be adjusted by altering the fine pin mill disc speeds. The centrifugal forces acting on both discs allow the processing of humid, greasy, and sticky products, primarily as a result of the utilization of the design within the wide chamber housing.

The feed material stands out for being embrittled by intensive mixing with liquid nitrogen. Ultrafine Pin mills are considered among the most reliable and versatile equipment currently available in the materials processing market. It features a generously dimensioned mill door that can be attached wide-open, for easier cleaning.
