A cement mill 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. Contents. [hide]. 1 History; 2 Materials ground.
The proven classical option for cement grinding. Whether employed as a two-compartment separator mill in an independent grinding system, or in combination with a high pressure grinding roll, the ball mill is a robust and reliable alternative for cement and granulated blast furnace slag grinding. Used in combination with.

On the other hand, in a Ball mill, the comminution takes place by impact & attrition. vmr technology. B. A suitable grinding bed is easily obtained in vertical roller mill with high efficiency separator which ensures high fineness of product. However, in the Ball mill, it is more difficult to get suitable grinding bed. vmr technology.
. very traditional technology for finish grinding-typically a ball mill and separator. With today's power price issues in the US, and the large experience base that the rest of the world has with the use of new technology in finish grinding, the US market is considering the use of modern vertical roller mill technology for cement.
For several decades the cement industry has successfully utilized Vertical Roller Mills (VRM) for grinding of raw materials and solid fuels. Most recently, this technology has been employed for the comminution of Portland cement, blended cements and slag cements. The VRM offers several benefits compared to the ball mill.

Department School of Engineering and Technology (Mechanical Engineering). Bahra University, Solan, India. Abstract: This work deals with the energy consumption in cement.
Ball Mill. Picture6. LNV Technology is known for its reliable products, which are developed with design standards and latest Technology. It is also known for fast and customized solution for product and process. The mill is of two compartments, gravity flow mill consisting of a shell with end covers, supported on white metal.
SAG mills. * Pebbles mills. * Ball mills. 2.1, Rod mills: -, Rod mills are usually used as the first grinding stage after crushing in the mining industry. Since the growth of the AG, SAG mill. circuits (with much higher capacities), rod mill technology is almost fallen into disuse. Their use is then generally limited to specialized cases.

If it is also assumed that the mean overall values of Si for a mixture of balls is the weighted mean of Si values for each ball size, equations are derived for calculating this mean value. As an example, the results are used in a mill simulation to show the quantitative effect of different ball mixes in a two-compartment cement mill.
