GEAR UNIT FOR VERTICAL ROLLER MILL. Vertical Mills. Vertical mills (such as bowl, roller grinding, ball-and-ring, and roller mills) are mainly used for comminuting limestone, clinker, slag, lime, gypsum and ores for the building industry and raw material processing. They reduce raw material from a thickness of 30 mm to a very fine-grained material.

The Loesche mill is driven by an electric motor through a special gear system. The roller forces are taken by a segmental thrust bearing in the gear system. The system of guiding the rollers in rocker arms is designed to accommodate a swing-out device; by connecting up an auxiliary cylinder to the rocker arm.

Feeders for Vertical Roller Mills. Williams industrial roller mills are used for a wide range of applications and materials, which means that the proper feeder selection is essential for high-capacity, trouble-free operation and more efficient production. You can customize your vertical roller mill depending on what material you need reduced.

India: Shree Cement has hired FL to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill.

Our modular drive system – the MAAG® GEAR MAX Drive – is the right fit for vertical roller mills with the highest power demands. The MAX Drive uses two identical gear units, including vertical electrical motors, to delivers the power necessary to rotate the mill table.

A vertical roller mill is a compact unit, making the footprint of the installation smaller and reducing the civil engineering costs when compared to a ball mill system. Savings are also made due to the method of construction of the two systems. Ball mills are built at the supplier's factory and transported to the cement producer's site.

MVR vertical roller mill with conventional drive. With a planetary gearbox and up to six grinding rollers, the MVR mill is the optimum solution – also in terms of economy - when it comes to producing small to medium output rates.
