efficient operation of heat power stations consuming coal as the energy carrier, for cement plants where clinker is grinded, for ceramic plants where clay is grinded and for other plants. A specific feature in running a ball mill is that the grinding mills are big power consumers, since grinding process is power-intensive. The electric power
If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Apr 01, 2014 Mass flow analysis. In the Tube-ball mill system, each feeder is driven by a variable speed electric motor. Right before the feed hopper, a bunker discharge valve is installed to control the mass flow. In the system, both the feeder motor current and discharge valve actuation position are measured.
Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent.
Ball mills grinder can be classified into lattice-type and overflow type according to the discharging types of raw material. The Main Structure of ball mill : 1. Main bearings with a large-diameter stick double row self-aligning bearings, replace the plain bearings to reduce friction, reduce energy consumption, the mill is easy to start. 2.
Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ect.It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
Feb 16, 2015 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.
