For many cement enterprises, energy saving has become the primary problem, at present, CHAENG's new dry cement production optimization and energy saving technology there are still many deficiencies, the need to control the cement production and optimization of reasonable operation parameters, thereby reducing the energy consumption of clinker, reduce production costs, and this is also conducive to better enterprise in the fierce competition in the market to be based.

Four, automatic control technology

New dry process cement production lines with hundreds of thousands of mechanical equipment,switches, valves, motors, and a dozen adjusting circuits and hundreds of analog detection points,so we must through the automatic control of management, to ensure the normal operation of the system and effective control of product quality, CHAENG present most widely is the graphical display technology, computer control technology, communication technology and distributed control of the distributed control system, through the system and technology to realize centralized management, ensure the reliability and safety of enterprise production.

Five. Optimization of new dry process cement production technology

High heat consumption problem has been more and more attention and importance of dry cement clinker production line firing, enterprises in the original production of technical equipment and technical conditions, through the production technology management, strengthen and optimize the production process and technology, make the production operation parameters remain within a reasonable range, further mining of the production system, so as to improve the clinker production, the following specific optimization measures:

(1) To strengthen the optimization of raw materials, full homogenization of raw material, the raw meal composition of reasonable control, the rate of change little; relax on the granularity of raw material requirements, considering the impact of the power consumption of raw meal grinding and grinding efficiency; control of coal reasonable margin of kiln coal optimize, reduce water and ash.

(2) Increase the equipment maintenance of production line, the correction of temperature measurement, feeding device and pressure measurement equipment, repair of wear equipment, reduce the system loss of air leakage and leakage; the levels of preheater inlet or outlet and feeding device is optimized, which can improve the efficiency of heat exchange and the dust collection efficiency; to improve the cooling machine heat recovery efficiency by adjusting the panel cooler.

(3) For firing the optimal control, the negative pressure to ensure the reasonable ventilation and honey smoke chamber under the condition of continuous commissioning coal quantity, raw feed quantity and kiln speed, wind and correction of all cyclones by optimizing the system, thereby reducing the temperature of exhaust gas preheater.
