Weima Electric (Shanghai) Ltd.

RENK KPBV gear units are the classic drive solution for medium and large vertical mills for coal, raw materials, bricks, as well as minerals.

The three-stage gear unit has a bevel gear and two planetary stages. It is the gear unit used in the third development generation of vertical mill drives. It was introduced to great success in 1998 and has been installed many hundreds of times since then. This technical solution has become standard today and was generally accepted on the market.

The round structure of the housing is ideal for diverting the milling forces into the foundation. The mill axial bearings integrated into the gear unit can absorb forces of over 3000t. The transmissible torque is greater than 3.5 million Nm.

KPBV gear units are produced in large quantities independently of orders and can be supplied at short notice. Versions adapted to customer preferences are provided within normal delivery times from the available stock and matching parts.
