The layout of cement production line: establish cement clinker production line in the mining area, and establish cement grinding station in the large and middle-sized cities which near the cement sales market. The most of raw materials of cement are the industrial wastes. The cement grinding station belongs to green environmental protection industry which can largely digest the slag, fly ash, coal gangue and other industrial wastes produced by cities. The cement grinding station provided by our factory has simplest process, easy to operation, less investment at equipments, energy-saving, environmental protection and can be mixed with more materials.
Processes
Silicate cement production line has representativeness most. With limestone and clay as the main raw material, the raw materials after crushing, burdening and milling, the materials are fed into cement kilns to burning mature. Then add appropriate amount of gypsum (sometimes mixed with mixed material or admixture).
?Add GMT demagnetizer between grinding and separation operations and screening, reduce the effect of magnetic reunion on the classification efficiency;
?Adopt MVS high-frequency vibration sieve to replace the original hydro cyclone and high-frequency fine sieving which streamline processes and improve efficiency;
?Adopt magnetic separation to instead of regrinding operation of products on the high frequencyvibrating screen sieve, solving the problem of ineffective;
?Change the original grading operations though magnetic separation into regrinding operations. It can reduce grinding fineness, and help to improve the operating efficiency of the overall process;
?Change grading operations into grinding magnetic operations, excluding part of gangue interfere with useful minerals, greatly improve qualified product content into the screen, and improve the efficiency of qualified useful minerals;
?Increase BKW-type magnetic separator to cope with tailings, make full recycle of useful minerals;
?Adopt DCJJ electromagnetic poly machine instead of the original ordinary magnetic agglomeration operations before selection process which saves water and improve quality;
? Adopt HTC automatic ceramic filter to replace the original disc vacuum filter.
First, dehydration the raw material slurry, then feed the material brick into wet kiln to be calcined into cement clinker. It is semi-wet method, also belongs to wet type cement production method.
The main advantage of dry type cement production line is low heat consumption (for example, the heat consumption of the dry kiln with preheater is 3140-3768 kj/kg ), and the disadvantages are uneven raw materials, heavy dust in the workshop and heavy power consumption.
