Extended Classifier Mill (ECM)

Extended Classifier Mill model ECM060

The Atritor Extended Classifier Mill contains a grinding rotor and an independently-driven classifier that controls particle size distribution. The grinding zone consists of vertical blades running within close proximity of a formed stator.

The rotor and stator can be made from a range of materials: stainless steel, hard cast iron, carbon steel, or tungsten carbide tipped carbon steel. The stator can also be made from a large variety of materials.

Typical products have a top size of between 20 and 100 microns. The mill is air-swept and can be run at a wide range of air volumes, depending on product characteristics.

The mill is modular in its construction, and can be custom-built in our in-house machine shop to customer’s specifications.

The ECM also has the advantage that it can be used as a dryer. By introducing hot air to the inlet of the mill, evaporative capacities up to 5t/h can be achieved.

The top of the mill is hinged to allow easy access to the rotor, liner and classifier for cleaning and maintenance.
