Rotary kiln process flow

If you want the rotary kiln to play a better role, you must not only master its structure but also its technological process. The content of the technological process is as follows
The raw materials are fed into the rotary kiln. The raw materials are controlled by manual gate valves and electronic controls at the bottom of the raw material warehouse. Pneumatic valves and electronically controlled flow valves are divided into seven areas into the raw material standard warehouse. After being inflated and homogenized, the raw materials are fed into the preheater through manual gate valves, electronically controlled pneumatic valves, electronically controlled flow valves, chutes, and belt hoppers. In the rotary kiln preheater, the raw material and the hot air flow exchange heat. After reaching the cyclone, it enters the decomposer for calcination. Then it enters the five-stage cyclone for material and gas separation. The material enters the rotary kiln for calcination. The rotary kiln decomposer consists of It consists of a body and an air outlet pipe. The tertiary air duct is tilted into the furnace on one side. The material enters the furnace from two discharge ports. The decomposed material is collected by the five-stage cyclone and then enters the rotary kiln for calcining. The rotary kiln grate cooler adopts a three-stage grate type. Cooling machine, the stroke adopts hydraulic method. The actual area of the grate bed is. The dust collected from the rotary kiln head is combined with the clinker from the grate cooler and sent to the three clinker warehouses through the skirt conveyor. Part of the hot air from the high-temperature section of the cooler enters the rotary kiln through the kiln head cover as the secondary air of the kiln, and part of it enters the decomposition furnace as the tertiary air. The hot air from the middle-temperature section of the cooler enters the coal mill to dry the raw coal. The remaining gas is discharged after being dusted by electric dust collector. For waste gas treatment in the atmosphere, the high-temperature gas in the preheater is sucked by a high-temperature fan, cooled by a humidification tower, and then used as a drying heat source for the raw material system or discharged into the atmosphere after being dusted by an electric dust collector at the end of the rotary kiln.
The process flow of the rotary kiln is provided by the technical department. I hope it will be helpful to you.
