Product infeed system for free flowing and powdery products. The CM is designed for homogenization of dry products to a specified particle size, reduction of oversized particles to the desired size and milling of agglomerates back to the initial size. A set of shims to adjust the clearance between the rotor and screen (0.5 mm to 3.0 mm) is supplied. It allows a flow rate of up to max 40 kg/h with a rotor speed of 0 – 1200 rpm. A safety interlock helps to prevent injuries.
