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 closedcircuit operation with a high efficiency thirdgeneration classifier would be between 075 and 098

Service OnlineJan 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.

Service OnlineThe following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a) Mill Geometry and SpeedBond (1954) observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account. As well mills with different

Service OnlineCombined grinding due to the narrow distribution of cement particles and the low spherical shape of the particles the cement requires relatively large water. At present the cement grinding of most cement enterprises adopts the double closed circuit combined grinding system of "roller press ball mill".

Service Online14 Cement Mill and Bag House . Clinker along with additives is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates the crushing action of the balls helps in grinding the clinker to a fine powder.

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.

Service Onlineof material in the reject stream. This allows to modify the cement particle size distribution thus obtaining a finer and better performing cement. Grinding aids act at two levels in the mill with the reduction of cement coating on grinding media and mill lining and in the separator with the improvement of classification process.

Service OnlineHowever particle size distribution is again a problem and roll presses are now increasingly popular as a "pre-grind" process with the cement finished in a single chamber ball mill. This gives good cement performance and reduces energy consumption by 20-40 compared with a standard ball mill system. Capacity of cement mills
