Rotary Kiln of Ceramsite Line/Frac Sand Plant with

Dry Process Rotary Kiln Cement Production Line

Cement Plant Working Flow:

a. Raw coal which stored in the stoke shed are conveyed into the raw meal silo by hoist after being matched.Then they are sent into the mill by rotary disc feeder. A Φ2.2 mx 5.8m air swept is used as coal mill. After bing separated by meal separator, meal is back to grind in the mill. Fine powders are sent into again, qualified coaldust are conveyed into pulverized coal bunker. The waste gas gose into bag filter to be treated then discharged into air. The coal power collected by the bag filter is regarded as the final goods,then sent into the kiln head coal power cabin. Standby heat source of the coal mill is supplied by the host blast stove.

b. Raw material, which stored in the raw material storedhouse, is conveyed into the raw-material silo located in the kiln outset by pneumatic transport. After measured, it is sent to air pipe between the firstsecond stage cyclones, then it goes into the Φ3.3 mx52m rotary kiln to be calcined, after preheating through firstsecond third forth fifth stage cyclone preheater in turn.

c.The waste gas is sent into the Φ4.8mx 28m conditioning and hardening and tempering, through one-stage cyclone from bottom-up in turn. Then it is sent into the to be uds separation. Finally, the waste gas is diacharged into air after be pumped into by dusting fan, kiln dust, which comes from dust catcher and conditioning tower, is conveyed into silo by chain conveyor, and then conveyed into raw meal homogenizing silo by conveyor.
