Lime rotary kiln calcination production line equipment, including vertical preheater system, transport tank, rotary kiln, combustion and vertical cooler, pulse bag filter and other equipment, a complete set of system equipment and reliable operation, high degree of automation, labor productivity, and product quality is good.
Lime rotary kiln calcination production line equipment, including vertical preheater system, transport tank, rotarykiln, combustion and vertical cooler, pulse bag filter and other equipment, acomplete set of system equipment and reliable operation, high degree of automation, labor productivity, and product quality isgood.
For different active lime production scale,the preheater is suitable for square, round and polygonal vertical preheatersof various scales, and the number of barbers is reasonably covered according tothe preheating area and the rotary dryer. The hydraulic push rod is used tofeed the rotary kiln and the equipment is operated reliable; the top of thesilo with level gauge control, to ensure the stability of the preheatermaterial layer height.
2. Rotary kiln:
(1) The size and the appropriate furnace,diameter and length;
(2) The transmission adopts speed motor todrive the kiln body, equipped with auxiliary motor, stable work and flexibleadjustment;
(3) Preheater kiln head spring-type sealstructure, simple, reliable and good sealing effect.
(4) Spare diesel engine driving force.
3. Rotary Cooler:
(1) The cooler is divided into four zones.Each zone can be controlled individually. The cooling air and the hot materialare in direct contact with each other. The cooling effect is good. Thetemperature of about 50 ℃ is not higher than the ambient temperature, and the temperature ofthe secondary air is preheated to 600 ℃ above calcination ;
(2) Cooler without moving parts, lessequipment maintenance.
Two channels, three channels or fourdifferent pulverized coal burning devices that use coal as fuel and match thesize and type of kiln, with full combustion, lively flame and good rigidity. Itdoes not hurt the kiln and has strong applicability and post-maintenance costLow, the key components of high temperature ceramic elements, stable andreliable performance and low investment system.
(2) Gas burner composed of natural gascombustion system, control valve group, gas through the pipeline control valvegroup, into the rotary kiln burner, the main and secondary wind mixedcombustion. Gas flow control flexibility. Gas burners consist of multiplehollow sleeves and helical body compositions, channel vortices or direct-flowversions of combustion air and natural gas burners, more uniform mixing ofcombustion gases and air, but it is also possible to control the flow of thewind so that the burner flame Shape according to the production ofself-regulation. The combustion system is also automatically cleared, emergencystop, safe and reliable.
