The distance >10m of described metal detector I 5 and described belt tramp iron separator 4.
Duty of the present invention is:
Virgin material high pressure roller mill deironing apparatus 1 is parallel with rim charge high pressure roller mill deironing apparatus, and new mineral aggregate and rim charge are carried out to deironing processing simultaneously.Wherein in rim charge high pressure roller mill deironing apparatus, if metal detector I 5 detects that containing ferrous material in mineral aggregate will send warning, control cabinet can be given an order belt tramp iron separator 4 is turned round, rim charge is returned to the iron tramp sucking-off on ribbon conveyer 2, be drained in the scum case 3 of its below.Rim charge after deironing feeds high pressure roller mill feed collection ore deposit ribbon conveyer 10 with together with virgin material after deironing after rim charge high pressure roller mill feeding metering device metering; and utilize high pressure roller mill inspection deironing apparatus again to examine iron test; if metal detector II 9 detects that containing ferrous material in mineral aggregate will send warning; control cabinet provides order; high pressure roller mill feed collection mine belt formula conveyer braking device starts; high pressure roller mill feed collection ore deposit ribbon conveyer 10 is shut down, remove residual a small amount of ferrous material.Mineral aggregate after deironing and inspection iron enters feed hopper 12 successively, and high-pressure roller mill and hopper 17, enter later operation.Rim charge high pressure roller mill deironing apparatus, high pressure roller mill check deironing apparatus, not only removed new for the ferrous material that contains in mineral aggregate, but also removed come from high pressure roller mill feed hopper come off liner plate containing ferrous material, avoided the damage of high pressure roller mill equipment, ensure the life-span of Roller of High, improved the operating rate of high pressure roller mill machine equipment.
In whole control system, rim charge high pressure roller mill feeding metering device and high pressure roller mill discharge control device can feed back to control cabinet by the circulating load of high pressure roller mill, when needs increase circulating load, the transmission device of the electric rotating plate 16 in hopper 17 starts, inwardly move in the top that promotes electric rotating plate 16, a part was fed to material in product to be originally assigned to rim charge and to return on ribbon conveyer 2, then control cabinet provides order, increase the speed of discharge ribbon conveyer 7 under high pressure roller mill returning charge storehouse, increase the ratio of returning to rim charge in high pressure roller mill feed.When needs reduce circulating load, the transmission device of the electric rotating plate 16 in hopper 17 starts, outwards move in the top that promotes electric rotating plate 16, the material that a part was fed in returning charge is originally assigned in product, then control cabinet provides order, reduce the speed of discharge ribbon conveyer 7 under high pressure roller mill returning charge storehouse, reduce the ratio of returning to rim charge in high pressure roller mill feed.The circulating load that high pressure roller mill can be effectively controlled in the combination of rim charge high pressure roller mill feeding metering device and high pressure roller mill discharge control device obtains qualified high pressure roller mill product.
High pressure roller mill feed hopper pressure control device feeds back the pressure in high pressure roll surface feed hopper by pressure sensor 14.When in high pressure roller mill feed hopper during hypotony, control cabinet provides order, increases the speed of discharge ribbon conveyer 7 under high pressure roller mill feed collection ore deposit ribbon conveyer 10 and high pressure roller mill returning charge storehouse, strengthens the material speed feeding in feed hopper.When in high pressure roller mill feed hopper during hypertonia, control cabinet provides order, reduces the speed of discharge ribbon conveyer 7 under high pressure roller mill feed collection ore deposit ribbon conveyer 10 and high pressure roller mill returning charge storehouse, reduces the material speed feeding in feed hopper.High pressure roller mill feed hopper pressure control device of the present invention can effectively be controlled the pressure in high pressure roller mill feed hopper in conjunction with rim charge high pressure roller mill feeding metering device, thereby needed static pressure while guaranteeing high pressure roller mill fragmentation guarantees to produce and carries out smoothly.
When high pressure roller mill need to overhaul, control cabinet provides order, the electric gate valve 15 that two inclinations in high pressure roller mill inspection control device are arranged symmetrically with starts, and plate tilts to be inserted into feed hopper 12 inside, until two plates stop the material in feed hopper 12.Now control cabinet provides order, and electric gate valve 15 stops.When maintenance finishes rear high pressure roller mill and will again turn round, control cabinet provides order, and two electric gate valves 15 start, and plate tilts to exit from feed hopper inside.Two electric gate valves 15 that inclination is arranged symmetrically with, feeding flow path direction, valve switch is easier, is difficult for producing stopping up.
The present invention configures rationally, compact conformation, and automaticity is high, and maintenance is little, and operating rate is high, is conducive to ensure produce carry out smoothly.
