Grinding mill process design. Choosing an appropriate grinding circuit configuration depends on your ore characteristics and mine plan. Outotec has extensive knowledge of comminution technologies and processes to ensure we provide the optimal solution for your needs.

A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water ().

The overall wear of the steel in the grinding mills occurs as a peeling of the steel surfaces at a constant radial rate per unit time. This concept although challenged at times was first introduced by Prentice in evaluating the wear of grinding balls and subsequently demonstrated on large ball mills.

Note After grinding oily or fatty foods it may be necessary to demount the mill and clean the mill casing cover and grinding plates. The mill comes with instructions on how to do this. If you are storing the grinding plates for several months in a humid environment it s a good idea to coat them lightly with vegetable oil to prevent rust.

SWECO Vibro-Energy Grinding Mills are the most versatile line of mills available today for fast low-cost particle size reduction to sub-micron range. Vibro-Energy grinding action achieves higher output per input horsepower precise control of size and distribution. Product contamination from media and lining wear is virtually eliminated.

The performance in all media mills is dependent on using the correct media type size and mill loading. New high performance beads have not only improved mill efficiency but also reduced wear on the beads and equipment. This along with long life easily justify the higher costs associated with these higher performance beads.
