Tumbling mills are designed for wet and dry grinding in a cyclic system.  Tumbling mills use two types of liners and grinding wheels.  Mills equipped with the steel liners and grinding mediums are used to grind materials that can contain metallic inclusions. Mills equipped with the ceramic liners and ceramic grinding mediums are used to grind materials that must not contain metallic inclusions.

An optimal ratio of the drum rotating speed to its diameter, properly shaped liners, an option to choose liners and grinding mediums with variety of shapes and materials have largely improved the performance of GB machines.

Compact design

Due to placing the mill and the drive on a common frame, one can easily change the mill’s preferred site of use at once, while at the same time diminishing the costs of both transportation and re-installation.


Our mills use the latest solutions available in the field of power transmission, which have significantly increased the working order of the entire system.

Thanks to many years of experience in machine construction and repair we were able to design the tube mills for a customer-friendly assembly and disassembly.
