The pendulum mill PM is a roller or horizontal mill. It is the further development of the proven Raymond and is suitable for fine grinding and drying soft to medium-hard ground material. Application examples include clay, bentonite, barite, phosphate, coal, quicklime, limestone and talc. Further areas of application include grinding pigments and chemical products.
The pendulum mill consists of a sturdy, cast mill housing and a rotor with a crosshead. The grinding rollers for the eponymous pendulum travel 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 grist 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 the required final degree of fineness, they flow through the mill classifier. A downstream aggregate skims it out of the air flow.

The input quantities for the various construction sizes range from 0.5 t/h to 150 t/h. The NEA pendulum mill easily realizes 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 grain sizes range from 10 μm to 1,000 μm.
