Shougang Mining Company waterworks concentrator crushing system is composed of 2 primary crusher. 17 Taichung crusher, 38 Crusher 44 shipped ore belt, light board and 34 vibrating screen. During the Long time, people has been using the the traditional relay control system chain.Low technical content, control methods are backward, equipment on, stop by the manual, work-intensive, low efficiency, long time empty – load operation of the system equipment, power consumption, equipment failure, in early 2003, the plant uses a PLC can program control system carried out a thorough transformation of the control of the broken system equipment. New system of centralized control, improved equipment chain opened the timeliness and effectiveness of the stop, the reactive power consumption to a minimum; real – time detection of equipment status; dynamic display screen via a computer terminal; When the equipment operating parameters beyond set parameters, timely alarm, has created favourable conditions for the implementation of the point overhaul; When running equipment failure, the pointed out the faulty equipment and related system equipment in a timely manner to stop the run, to avoid the expansion of the accident. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. Crushing system of Shuichang Concentrator automated centralized control improving production efficiency and reduce the consumption of energy, belts, mechanical spare parts and electrical spare parts, brought hundreds of million of annual benefits of intensive management. Control room separate server l table (Sen-er) network switch Switch can also be used with the workshop director, shop scheduling, allowing management to keep abreast of the underlying production and equipment operation.Cascade control system greatly improves the system s dynamic quality, give full play to the processing capacity of the crusher, compared with the manual, packed to about 50% of the ore rate from the previous manual increaser to 85% more, to achieve the control objectives.
