- →Rotary Kiln
Zheng mine machine production of the rotary kiln, kiln, kiln inlet seal device used advanced technology to ensure the reliability of the seal, but also to provide users with advanced efficient shaft preheater, five cyclone preheater. rotary kiln process is as follows:
the raw material into the rotary kiln, the raw material by the end of the raw material library manual valve, electronically controlled pneumatic valves, electronic control flow valve in seven districts into the raw material standard positions; inflatable homogenization raw materials by the manual valve, electronically controlled pneumatic valve, electronically controlled flow valve, chute, into the tape bucket, feed preheater; rotary kiln RF5/5000 preheater, the raw material and hot air heat exchange, reach of C4A and the C4B cyclone into the calciner calcining, and then into five cyclone separation of feed gas, the material into the rotary kiln; the rotary kiln NST-calciner furnace and vent piping, three times the duct unilateral tilted into the furnace, the material from the two feed opening into the furnace,
the decomposition of materials collected by the five cyclones into the rotary kiln; rotary kiln grate cooler using three sections of the grate cooler (NC39325), using the stroke hydraulic methods; grate area of 121.2m2. Dust with a grate cooler clinker in the rotary kiln head collecting the convergence of the three clinker by apron conveyor into the library. High-temperature segment of the cooler part of the hot air through the kiln hood into a rotary kiln as the kiln secondary air into the calciner as tertiary air, the cooler the temperature segment of hot air into the coal mill drying of raw coal; the rear of the residual gas by the electric dust collecting dust high-temperature gases at high temperatures into the atmosphere; gas processing, preheater fan suction, then the conditioning tower after cooling as the heat source of raw material drying or rotary kiln tail ESP dust into the atmosphere.
