Method of Operation

There are various ways to dose the feed material into the mill according to the requirements, such as vibratory feeder, feed screw or a rotary air lock. The rotor is aligned vertically and together with the stator, they form a cone shaped grinding chamber

This geometrical arrangement allows the grinding gap to be easily set by raising or lowering the stator.

Size reduction or conditioning occurs between the impact edge of the rotor and the wear resistant grinding path. The degree of fineness or conditioning is controlled by the grinding gap, circumferential speed of the impact edge of the rotor, volume of air, rotor type as well as the type if grinding path, therefore resulting in preferred combinations for pulverizing, mixing, dry grinding and coating.

Very often there is no requirement for a sifter to control the upper particle size. A blower suctions the product out of the mill and onto either a cyclone or filter separator.

The PALLMANN ConoMillTM, type PLK is available in a pressure shock resistant design up to 10 bar for dust explosive materials.

The rotors and grinding paths can be made of weare resistant ceramic specially designed for abrasive hard materials and for an iron free grinding in the food industry. Also for food or chemical industries, the mill is available in stainless steel and/or GMP compliant versions.
