the demand for cement is ever increasing
The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant progress has been achieved. The increasing demand for “finer cement” products, and the need for reduction in energy consumption and green house gas emissions, reinforces the need for grinding optimisation.
the cement grinding process
The cement clinker grinding circuit reduces the feed from 80% passing size between 10 and 20 mm to 100% passing 90 microns. The size reduction takes place in a two- compartment tube mill; the first compartment of the mill is shorter than the second compartment. The coarse clinker is ground in the first compartment where larger balls (80, 60, 50 mm) are used and the fine grinding is done in the second compartment where smaller balls (below 25 mm) are used. A diaphragm (see Figure 1) separates the two compartments and allows only particles below a certain size to pass to the second compartment. Ground material exits the mill through the discharge grate which prevents grinding balls from leaving the mill. A proportion of material, mostly fines, is “air-swept” out of the mill. The final product is the fine fraction of the air classifier and the coarse fraction returns to the mill.
cement ball mill for sale
Ball mill is the vital equipment for regrinding after primary crushing. It is extensively applied in cement, silicate products, new construction material, refractory material, chemical fertilizer, ferrous and non-ferrous metals beneficiation and glass ceramics industries.It is great choice for dry or wet grinding any kinds of minerals and other grindability materials.
Ball mill is a widely used ultra-fine grinding mill in industrial production. Ball mill has a variety of types, according to different ways of discharging materials,ball mill could be in grate and overfall style.There are also tube mill, cone mill, etc.
