Cement manufacturing - brief description of a cement mill. 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.

In cement production, tube mills having multi-chambers are traditionally used either in open or closed circuit operations. After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding.

Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

The L/D ratios of ball mills range from slightly less than 1:1 to something greater than 2:1. The tube and compartment ball mills commonly used in the cement industry have L/D ratios 2.75:1 or more. The fraction of critical speed that the mill turns depends on the application, and most mills operate at around 75% of critical speed.

Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.

Aug 05, 2014· The UMS mill type was developed around 1983, and the reason was a demand for increased ventilation of cement mills. In ball mill, ball has to be charged around 30-32% in first and second compartments.

Comparison of open and closed circuit HPGR application on dry grinding circuit performance. ... In cement production, tube mills having multi-chambers are traditionally used either in open or ...

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.

The Preliminator mill is a type of ball mill used for coarse grinding in open circuit or for fine grinding in closed circuit. Preliminator mills are widely used in the cement industry for the reduction of cement raw materials and clinker.

Lvssn provides various grinding equipment for cement production line, including: Grinding mill,Ball mill,Rod mill,Roller press,Veritcal mill,Pipe mill

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 ...

Ball Mill Circuit In Cement Production. cement production case Polysius twocompartment ball mill and a Polysius Sepol dynamic high efficiency air classifier were operated in closed circuit to obtain the required cement types Figure 1 Simplified.

Ball mill cement grinding circuit. The application of ball mill in cement industry dates back more than 100 years. The ball mill for cement grinding plant is mainly of high fineness, dry grinding method, and the process is mainly of open circuit process and closed circuit process.

Compared with open-circuit process, cement material can be processed effectively in the closed-circuit process. 4.Fineness of finished product. Just like feeding size of cement raw material, the finer the output material, the lower the capacity of the ball mill; the coarser the finished product, the higher the capacity. Ball Mill Principle. 4 ...
