The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".

terial present in the ball mill cement, which in turn reflects the greater number of impacts and the inherent inefficiency of ball mill grinding. In more general terms, a typical particle size distribution for a ball mill system in closed-circuit operation with a high- efficiency, third-generation classifier would be between 0.75 and 0.98.

amount of water for cement ball mill - dezandtuinnl. amount of water for cement ball mill Ball mill A typical type of fine grinder is the ball millA slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls
Overview. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
Aug 23, 2017· The clinker (dark porous nodules of 6-50 mm diameter) is further cooled with air or water. It is ground to a powder in a ball mill, along with a small amount of gypsum, to obtain portland cement. (Gypsum is added to avoid the flash set of the ground clinker.)
Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill ...
The ball mill is a spinning cylinder that has a sacial lining held in place by hundreds of bolts, the heads of which can be seen in the photo above. Different materials are combined in the ball mill, so this is also where initial blending takes place. Common materials are limestone, shale, sandstone and iron.
This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.

Jan 07, 2015· ~ Nael Shabana 20104~ 1.0 Definition of Ball/ Tube Mill: Ball or tube mills are rotating steel cylinders where size reduction of the mill feed is performed by motion of the grinding media. Rotation of the mill cylinder raises the pile of mill feed and grinding media to an optimum high, necessary for grinding operation.
