Dry Ball Mill For Cement Process

Dry ball mill for cement production process requires stable thermal institution, reliable running of equipment, and adjustment of parameters in time.

1, Crushing And Pre-homogenize

(1) Cement crushing plant in the production process, most of the material to be broken, such as limestone, clay, iron ore and coal. Limestone is the largest raw material dosage of cement production, mining the granularity is large, high hardness, limestone crushing plant occupies an important place in the crushing of materials.

(2) The raw material of pre-pre-averaging technique is the raw material storage, access, process, stacker for the application of scientific technologies, realization of preliminary raw materials are, raw material yard of both storage and functionality.

2, Raw Material Preparation

Cement production process, to produce 1 ton of Portland cement grinding on at least 3 tons of materials (including raw materials, fuels, clinker, mixtures, gypsum), according to statistics, the dry-process cement production line of grinding operations needed to power more than about 60 per cent of plant dynamics, in which raw material grinding more than 30 per cent, coal Mills accounted for about 3, grinding about 40 per cent. Therefore, rational selection of grinding supplier and processes, optimization of process parameters, proper operation, the control of operation systems, is of major significance to ensure product quality, reduce energy consumption.

3, Homogenizing

New dry milling ement production process, the stability of raw ingredients into the pits is a prerequisite for stable thermal regime of the clinker burning, homogenizing system stability into the cellar last line of the raw constituents of essential role.

4, Preheat Decomposition

To raw of preheating and part decomposition by preheating device to complete, instead of rotary kiln part function, reached shortened back kiln length, while makes kiln within to stacked State for gas material for hot process, moves to preheating device inherent suspension State Xia for, makes raw can with kiln within discharges of hot gas full mixed, increases has gas material contact area, heat transfer speed fast, hot Exchange efficiency high, reached improve kiln system production efficiency, and reduced clinker firing hot consumption of purpose.

5, Grinding

Dry ball mill for cement process is the last operation of cement manufacture, but also consumes the most amount of processes. Cement ball mills is most used, it main function is to cement clinker (gelling agent, performance tuning and materials, and so on) grinding to a suitable size (fineness, specific surface area, etc), a certain particle size distribution, increasing its hydration area, accelerates hydration speed, meeting setting, hardening requirements of cement paste.
