Pendulum Mill PM

The pendulum mill PM is a roller or horizontal mill. It is the further development of the proven Raymond Mill and is suitable for fine grinding and drying soft to medium-hard ground material. Application examples include clay, bentonite, barite, phosphate, coal, burnt lime, limestone, and talc. Further areas of application encompass grinding pigments and chemical products.

Pendulum Mill: Proven Grinding Concept, Robust Construction

The pendulum mill owes its long service life in part to the unique combination of a sturdy, cast mill housing and a rotor with a crosshead. The grinding rollers of the eponymous move at medium speeds on the grinding ring.

The arising centrifugal forces crush the grist between the grinding rollers and the grinding ring. Rotating shovels guide the grist from the mill bottom to the grinding zone. Then, system air transports the ground particles from the grinding zone to the classifier.

The classifier rejects the coarse product and guides it back into the mill for re-grinding. If the particles have achieved the desired fineness, they pass through the mill classifier. A downstream aggregate separates it out of the air flow.

Minimal Grinding System Energy Requirements

The input quantities for the various mill sizes range from 0.5 t/h to 150 t/h. Our pendulum mill achieves high requirements for grain size distribution easily and extremely energy efficiently, even in case of the highest demands regarding the fineness to be achieved. The achievable upper particle sizes range from 10 μm to 1,000 μm.
