The Alpine UPZ Ultraplex Fine Impact Mill are truly flexible. Designed with ultimate versatility in mind, this one unit can accomplish a multitude of size reduction tasks. A wide variety of grinding inserts are available through the entire line of mills. The mill is also offered with a counter-rotating (Contraplex) set of pins for added shear for difficult to mill products. The pharmaceutical version of this work horse has been designed specifically for cGMP compliance from the ground up. Size reduction of soft to medium soft material can be accomplished at rates from 3 to 700 Kg/hr depending on feed material and final size requirements.

Alpine UPZ Ultraplex Fine Impact Mill can also be integrated into Stott Isolators. This arrangement provides a completely integrated system capable of containment levels as low as 1 micro-gram/cubic meter.

Operation of the mill is simple. Material is introduced to the mill via feed device such as a rotary air lock or volumetric/gravimetric feeder through the mill’s inlet. The inlet directs the material to the grinding chambers center. The grinding toll rotates at high speed, creating centrifugal force that will accelerate the pharma-powder outwards. The particles outward flow hurls them at high speed against the pins or other grinding media where the impact will cause the particles to fracture.
