Sanitary Mills

Sanitary Mills

Sanitary Mills are commonly Pin Mills used in applications that need proper sanitation. This mill provides coarse to fine grinding of friable powders, flakes and granules into controlled particle sizes.

High-speed rotation of the inner disc creates centrifugal force that accelerates bulk material entering the central inlet of the opposing stationary disc. As material travels from the center to the periphery of the discs at high speed, it passes through a path of five intermeshing rows of rotating and stationary pins, with the desired tight particle size distribution obtained by controlling the rotor speed.

Setting the infinitely variable rotor speed between several hundred rpm and 5400 rpm provides the flexibility to use the machine for coarse grinding and de-agglomerating as well as for fine grinding down to 400 mesh.

Vertical orientation of the mill housing results in a smaller footprint than horizontally-oriented units, and allows the outer disc to hinge open, providing instant access to all product-contact surfaces for cleaning and inspection.
