Alpine Contraplex CW
The Alpine Contraplex CW mechanical impact mill was originally designed for the processing of cocoa powder but has since found many uses beyond that industry. These wide chamber mills perform trouble free ultra fine grinding of difficult products, even in continuous operation.

Ideally suited for size reduction of crystalline or needle like particles and fatty or oily feed materials which are found in both the pharmaceutical and food industries. The units wide chamber housing prevents internal coating and blockage problems. The unit's power requirements are lower compared to some other milling technologies, in some cases up to 50% lower depending on the product.

Ultra fine particles are achieved by the high relative speed of the discs. Adjustment parameters such as direction of rotation, disc speed, air flow and feed rate combinations permit milling conditions that can be customized to virtually any milling problem. Depending on the product, process rates can be as high as 5200 kg/hr.
