Process description
(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.
