Weima Electric (Shanghai) Ltd.

RENK KPAV gear units are the classic drive solution for vertical mills for coal and smaller raw materials, as well as minerals.

The two-stage gear unit has a bevel gear and a planetary stage. It is the gear unit used in the second generation of vertical mill drives, and was introduced to great success in 1979. The KPAV therefore represents the first time that RENK used a two-stage bevel planetary gear unit for vertical mills. This technical solution later became standard and was adopted by all of the players 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 400 t. The transmissible torque is well over 500,000 Nm.

Features

• Torques of 140 to 480 kNm for smaller vertical mills

• Proven in use for 40 years 

• Integrated lubrication system, no connecting tubes, which results in short commissioning time and no contamination of the hydraulics during the installation of the system

• Overdimensioned mill radial bearings

• Sophisticated monitoring, optionally also with the RENK VIBmonitoring System for the automation of regular maintenance checks
