To investigate the effects of grinding media shapes on the grinding kinetics of ball mill cement clinker, the grinding effects with 20mm balls and 2020mm cylinders on six different size fractions, i.e. 4.75+4.00mm, 4.00+3.35mm, 3.35+2.36mm, 2.36+2.00mm, 2.00+1.70mm and 1.70+1.18mm of cement clinkers, were studied in a laboratory scale ball mill. The specific rate of breakage and the primary breakage distribution function were compared for the balls and cylinders. Result shows that cement clinker obeys first-order grinding kinetics in the case of both balls and cylinders. The specific rate of breakage of cylinders is higher than that of balls. The primary breakage distribution parameters are dependent on the initial feed size. The value of cylinders is higher than that of balls.
The effects of balls and cylinders on the clinker's specific rate of breakage were investigated. The results showed that the specific rate of breakage provided by cylinders is higher than that of balls. 2.00+1.70mm is an optimum feed size for 20mm diameter balls and 2020mm diameter cylinders. At that feed size, the value of Si is maximized.Download : Download full-size image

Slag powder is high-performing admixture for concrete in that it increases the concretes ability to resist compression, tension, shear, and bending stresses. A major trend that characterizes the building material industry is to replace equal amount of cement with slag powder in making concrete or cement products.
Cement production line is the production line composed of a series of cement production equipment, mainly involving crushing, prehomogenization, raw material preparation and homogenization, preheating and decomposition, sintering of cement clinker, cement grinding and packing and so on.
The particular heat treatment technology is used for the big gear ring manufactured by Xinxiang Great Wall Machinery which makes the improvement in the structure optimization and the hardness of the product. The wear-resistant and anti-impact performance is also enhanced greatly.
The cement kiln, also called cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment for the new dry type cement production line. This cement equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device.
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. Cement ball mill is not only suitable for over-flow grinding.
Our raw materials vertical roller mills are widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials.
Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.The drum is generally divided into two or three chambers, with different size grinding media. As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further.
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.Gypsum is interground with the clinker in order to control the setting properties of the cement. Clinker grinding uses a lot of energy and the cement becomes hot - this can result in the gypsum becoming dehydrated, with potentially undesirable results - see the link at the bottom of this page for more information.
Articles like this one can provide a lot of useful material. However, reading an article or two is perhaps not the best way to get a clear picture of a complex process like cement production. To get a more complete and integrated understanding of how cement is made, do have a look at the Understanding Cement book or ebook. This easy-to-read and concise book also contains much more detail on concrete chemistry and deleterious processes in concrete compared with the website.
Almost everyone interested in cement is also concerned to at least some degree with concrete strength. This ebook describes ten cement-related characteristics of concrete that can potentially cause strengths to be lower than expected.

Cement ball mill is a kind of cement grinding equipment commonly used in cement plants. It is mainly used for grinding materials in cement clinker section. Cement ball mill is widely used in cement production, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal mineral processing, glass, ceramics, and other industries. It is the ideal grinding equipmentfor cement clinker, limestone, gypsum, slag,ore,and othergrindable hardness materials.
In the process of cement production, cement raw meal is calcined in a rotary kiln to obtain cement clinker. After the cement clinker is cooled, adding an appropriate amount of gypsum and additives. Put the mixture into cement mill and grinding to the appropriate particle size, so as to obtain the finished cement products.
As one of cement ball mill manufacturers with many years of research and development experience, not only our cement ball mill price is reasonable, but also the cement ball mill operation is simple and with high-level automation.
Moreover, the cement ball mill has strong adaptability to materials and a large crushing ratio, which can conveniently control the fineness of the abrasive materials. These advantages make cement ball mill widely used in cement manufacturing, metallurgy, chemical industry, mining and other fields.
