Description of the 300tpd clinker grinding station
l Raw material storage yard and conveying
The clinker,gypsum, mixed material are transported to the storage place for storage, there set one 40×102m rectangle storage area which store the clinker, gypsum and mixed material distributed as per the storage capacity.the mixed material and gypsum of inlet size ≤200mm is transported to the special discharge pit by the dozer and conveyed by belt conveyor to cement dosing silo after being crushed to ≤25mm by the jaw crusher
l Cement proportioning silo and conveying
There set three Φ6.5×18m cement dosing silo (steel bin) to store the clinker, gypsum, mixed material. such three material are transported to the cement mill system after being weighed by speed adjusted belt weigher under the silo
l Cement grinding and conveying(closed circuit ball mill system)
The three material after being mixed shall be transported to ball mill for grinding, the mill adopt closed circuit, the cement from the mill shall be transported to the N1000 O-Sepa separator, the coarse powder from the separator shall be transported to the mill inlet through air chute, the finished product from the separator is transported to the Φ10×24m cement silo by bucket elevator. The mill outlet strength the ventilation to control the air flow inside the mill to reduce the over-grinding, the finess which collected by the bag filter is directly transported to the cement silo, the dust content of the waste gas after being purified is ≤50mg and directly emitted to the atmosphere. The average system capacity is 24~26t/h.
l Cement storage and conveying
Cement silo temporally consider one Φ10×24m storage silo,the total storage capacity is 3500t,storage period is 3 days.the quantity of cement silo can be adjusted as per the actual condition.the cement in the cement silo can be directly transported to the cement packing system.
l Cement packing and truck loading
Adopt one 8-spout rotary packer for cement packing; packing capacity is 100t/h;packed cement can be directly sent to bagged cement truck by two-unit automatic bagged cement loaders
l Air compressor station
The whole plant set one air compressor station with 2 sets of air compressor with the gas displacement 19m3/min,the discharge pressure is 0.8Mpa.the air compressor station shall meet the requirements of gas-control valve,measuring meter and pulse type bag filter.
l Center laboratory room
There is one center laboratory room(two-floor laboratory room in the center control room) inside the plant for conventional chemical analysis and physical test to raw material,semi-finished products and finished products to ensure quality of products inside the production plant; thus, quality of cement can be scheduled,managed and supervised.The power source of production line is 10.5kV 50HZ and 440V 50HZ. Total loading capacity is 1698kW,among them 10.5kV 50HZ 1020kW, 440V 50HZ 678kW.
