Munson Machinery has launched its new pharmaceutical-grade pin mill, Model CIM-18-S316. Its variable rotor speed grinds friable powders, flakes and granules into controlled particle sizes ranging from coarse to fine. Both outer and inner discs can swing away from unit on cantilevered arms, providing access to both sides of both discs and mill housing for cleaning and sanitizing. Constructed of 316-stainless steel, the mill features sanitary butterfly valve on air intake, sanitary fittings at material intake and discharge, and wash-down-duty motor.
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 precision-machined rotating and stationary impactor pins, with the desired tight particle size distribution obtained by controlling the rotor speed.
Constructed of 316 stainless steel, the unit features a sanitary butterfly valve on the air intake, sanitary fittings at the material intake and discharge and a wash-down-duty motor. Vertical orientation of the mill housing on tubular stainless steel legs results in a smaller footprint than horizontally-oriented units.
