what is the size and function of cement mill

Aug 29, 2018· The mill output is a function of mill feed size as well as the product size, if other variables like Mil Diameter, load in the mill, RPM of the mill etc. are kept constant. If input size fraction is reduced the output will increase and if output size is reduced the mill output will also reduce.

The cement mill

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. The drum is generally divided into two or three chambers, with

Cement Milling Understanding Cement

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.

Rawmill Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

Particle size analysis reduces cement manufacturing

Cement performance is a function of composition and fineness (particle size). Composition is controlled by manipulating both the feed to the kilns and the reaction conditions, principally temperature. Milling circuits reduce the resulting clinker to fine cement. The traditional measure for fineness is Blaine number, but increasingly cement producers are switching to laser diffraction particle

The cement kiln

The heating process is efficient because the meal particles have a very high surface area in relation to their size and because of the large difference in temperature between the hot gas and the cooler meal. Typically, 30%-40% of the meal is decarbonated before entering the kiln. A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is

ball mill cement grinding mill

ball mill cement grinding mill. Dec,several factors affect the efficiency of a ball mill for cement grinding in this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency mill geometry and speed according to bond,the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed


consisting of a tube ball mill and a high efficiency separator was introduced through the matrices of grinding and classification. The grinding matrix was calculated using the selection and breakage functions, whereas the classification matrix was defined from the Tromp curve of the separator. The results of field experiments carried out at a pilot cement plant were used to identify the model

Drying the material: In the dry grinding process, it is very important that the material to be ground has a humidity of under 2% in order to obtain a good mill performance. When the raw material has a humidity of between 2 to 7%, it is dried

Optimization of Cement Grinding Operation in Ball Mills

18/07/2016· Optimization of the Cement Ball Mill Operation. Optimization addresses the grinding process, maintenance and product quality. The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. Consistent quality and maximum output with lower specific power consumption results in lower operating costs per unit of production.

Cement : Physical Properties and Types of Cement

Fineness, or particle size of Portland cement affects Hydration rate and thus the rate of strength gain. The smaller the particle size, the greater the surface area-to- volume ratio, and thus, the more area available for water-cement interaction per unit volume. The effects of greater fineness on strength are generally seen during the first seven days. When the cement particles are coarser

Cement Plant Process and Instruments Used

22/10/2015· Cement Mill 22. The clinker, gypsum, flyash with the help of hopper is fed on the feeding belt from where with the help of conveyor belt is fed into the hoppers from where it is moved to the ball mill, flyash is fed if the cement is PPC and clay is fed if cement is OPC. The course material once moved from the outlet is moved to the bucket
