2.1000tpd cement production line
To build a production line of 1000t/d clinker cement, that is, to produce 1000 tons of cement clinker each day, 300,000 tons per year, to produce portland cement more than 347,100 tons. The output will vary according to product variety and class.
Model selection of process: To adopt the advanced technology in dry 5-stage cyclone preheater, calciner and rotary kiln, which is developed and manufactured by China.
(1) Limestone crushing and transportation
After limestone is conveyed from mine to plant, if crusher is switched on, LS will be directly unloaded to receiving pit, and then by heavy duty apron feeder sent to single hammer crusher PCF1616 to be crushed, if crusher is switched off, LS will be unloaded to open-air stockpile, and then sent to receiving bin via loader for crushing.
The crushed limestone is sent to two limestone dosing silos (dia.Φ12m) by belt conveyer, elevator and tee valve.
(2) Auxiliary material crushing and conveying
When the exclusive receiving pit is free, clay is unloaded directly to the pit, and then sent to clay proportioning silo via apron feeder, tooth crusher, belt conveyer and elevator. When the receiving pit is full, clay will be firstly stacked at shed, and then conveyed by forklift to receiving pit when it is free, at last, it is conveyed to clay proportioning silo by apron feeder, crusher, belt conveyer and clay proportioning silo.
When the exclusive receiving pit is free, iron ore and sandstone is unloaded directly to the pit, and then sent to respective proportioning silo via raw crusher, elevator. When the receiving pit is full, they will be firstly stacked at shed, and then conveyed by forklift to receiving pit when it is free, at last, it is conveyed to respective proportioning silo by crusher and elevator.
(3) Coal homogenization
Raw coal is unloaded directly to the pit after coming into plant, and then sent to raw coal preblending stockpile via apron feeder, belt conveyer, elevator and belt conveyer with discharging trolley, or firstly unloaded to open-air stockpile, and then conveyed by forklift to receiving pit subject to inform, at last, it is conveyed to raw coal preblending stockpile through apron feeder, belt conveyer, elevator and belt conveyer with discharging trolley. The blended raw coal is sent to raw coal bin through forklift and belt conveyer.
(4) Raw material proportioning silo and conveying
Raw material proportioning silo is composed of two concrete silos and three steel slab bins, and be measured by variable speed belt scale. Limestone silo consists of two Φ12m concrete silos, used for storage and proportioning. The proportioning bins is Φ6m,Φ6m and Φ6m respectively for clay, sandstone and iron ore.
(5) Raw mill & waste gas treatment at kiln inlet
Proportioned raw material will be fed onto the air swept drying mill with size of Φ3.8×8.6m. In the process of rotating, raw meal will be raised by material raising device in the raw mill and sufficiently contact with hot gas from high-temperature fan at kiln inlet. By this means, raw meal will be dried. Dry raw meal is ground in the mill. Then the raw meal will fed onto high efficiency separator. Fine powder will be fed onto the raw meal-homogenizing silo via electric flap valve and air slide while coarse powder returned to the mill via electric flap valve and air slide. Hot gas from preheater goes through humidification tower and high-temperature fan and then divides into two parts, one part goes directly to electric dust collector, and the other part goes to raw mill head, and then 1/8 of this part goes to mill end. Waste gas out of mill firstly goes through high efficiency separator and raw mill fan (with inlet regulation valve), and joins the waste gas to the electric dust collector. After that, the waste gas will be purified by the electric dust collector and drained to the air.
