Ore mill MML

for metalsmineralball

The metal magnetic mill liner (MML) is a wear resistant steel-encased magnet. It combines the best qualities of steel and magnetic liners. The magnet holds the metal magnetic liner to the shell and retains ball chips and magnetic minerals to form a solid protection layer which serve as the wear liner. The ball chips and magnetic minerals are retained continuously and therefore the liner may last for years without any maintenance. The metal magnetic mill liner with the longest service life has been in service for over 10 years. Installations show that magnetic mill liners: Are safe and easy to install Drastically reduce maintenance costs Increase mill availability Prevent back washing of mill shell Can lower medium consumption Can reduce noise levels Can reduce/eliminate mill leakage Can improve the working environment Magnetic Mill Liner applications include secondary ball mills and regrind ball mills. Proven Performance The metal magnetic mill liner has been in use for years and has provided higher grinding efficiencies. The thickness of the metal magnetic liner with the protection layer is less than that of a conventional liner, resulting in a greater working volume. The metal magnetic mill liner also creates a wave form that is generated by the magnetic force and provides optimal attrition by lifting the material being ground. The higher attrition results in less abrasion and impact, which promotes a higher charge pressure and grinding efficiency. Grinding ball chips and other debris discharged from a ball mill can cause extreme wear to downstream processing equipment
