Introduction of Cement rotary kiln:
Cement rotary kiln is the main equipment for dry and wet production of cement clinker.Rotary kilns are widely used in metallurgy, chemical industry, construction, refractories, and environmental protection industries. The rotary kiln firing system is equipment with technological innovation.This system adopts the domestic advanced technology,such as the most advanced hydraulic block wheel device, a high measurement accuracy of measurement piston pump, high-precision control valve and contact-type graphite block sealing device.
Features of Cement rotary kiln:
1. Stable function, low energy consumption, high output, easy to operate. Rotary kiln’s structure is simple, production process control conveniently and reliably and it is less wearing parts and high operation rate.
2. One hand,rotary kiln is the combustion equipment,in which coal powder burns to produce heat;Another hand, rotary kiln is the heat transfer equipment,raw materials absorb the gas heat to burn. Fuel combustion, heat transfer and material movement must be reasonable co-ordination to make the heat produced by material burn transfer to raw material timely when raw material go through the rotary kiln.This can reach the high-yield, high-quality and low consumption of purpose.
3. The rotary kiln firing system is equipmented with technological innovation,This system adopts the domestic advanced technology,such as the most advanced hydraulic block wheel device, a high measurement accuracy of measurement piston pump, high-precision control valve and contact-type graphite block sealing device.
4. Easy to operate, reliable use. Stabilize the thermal system, and improve the equipment operation rate, increase 10% operation rate compared with the same specifications equipment, production increased by 5% -10%, reduction 15% heat loss.
