A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill.
Using a reasonable figure for the energy consumption in a ball mill, 30 kWh/t, he concluded that ball mill efficiency, based on the energy consumption for interparticle breakage, will be between 40% and 60%.
In order to improve efficiency of the power draw and prolong the life of the discs, GrindForce rotors were installed into the mill. Immediately after the installation of the castellated rotors, a benefit in the energy efficiency was observed.
Vertical roller mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, cements and ceramics. It is an energy efficient alternative for a ball mill .
The ball mill has been the industry's workhorse for over a century and despite its estimated meagre four per cent efficiency, little has changed over the years other than increases in the wear resistance of mill internals and the scale of the equipment.
Stirred mills are primarily used for fine and ultra-fine grinding. They dominate these grinding applications because greater stress intensity can be delivered in stirred mills and they can achieve better energy efficiency than ball mills in fine and ultra-fine grinding.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
