PBLZ horizontal mill gear unit

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

The three-stage gear unit has a spur gear and two planetary stages. It was introduced to great success in 1998 and has been installed nearly one hundred times since then. By introducing the PBLZ, RENK created a robust gear unit concept for the central drive system of ball mills. It very deliberately serves as the opposite of so-called lateral drives. In contrast to such solutions, there is no contamination by lubricating oils due to the ingress of cement and no wearing of the gear rim with the PBLZ.

If the ball mill is suitably designed, it is possible to forgo the connecting coupling, which is part of the scope of delivery of the PBLZ. The gear unit is then positioned so that it rides on the mill.

PBLZ gear units use components of the KPBV system.
In addition to the mill drive coupling, a positioning auxiliary drive with an automatic overrunning clutch, a lubrication system with connecting lines, and the option of a control device are included in the delivery. RENK can also specify and deliver the main engine.
