Described metal detector I 5 and the distance >10m of described belt tramp iron separator 4.
Duty of the present invention is:
Virgin material high pressure roller mill deironing apparatus 1 walks abreast with rim charge high pressure roller mill deironing apparatus, carries out deironing process to new mineral aggregate and rim charge simultaneously.Wherein in rim charge high pressure roller mill deironing apparatus, if metal detector I 5 detects in mineral aggregate will send warning containing ferrous material, then control cabinet can be given an order and belt tramp iron separator 4 is operated, rim charge is returned the iron tramp sucking-off on ribbon conveyer 2, be drained in the scum case 3 below it.Rim charge after deironing feeds high pressure roller mill feed collection ore deposit ribbon conveyer 10 after the metering of rim charge high pressure roller mill feeding metering device together with the virgin material after deironing; and deironing apparatus examines iron test again to utilize high pressure roller mill to check; if metal detector II 9 detects in mineral aggregate will send warning containing ferrous material; control cabinet provides order; high pressure roller mill feed collection mine belt formula conveyer brake starts; high pressure roller mill feed collection ore deposit ribbon conveyer 10 is shut down, removes residual a small amount of ferrous material.Deironing and the mineral aggregate after examining iron enter 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 removing only new in mineral aggregate containing ferrous material, but also eliminate come from high pressure roller mill feed hopper come off liner plate containing ferrous material, avoid the damage of high pressure roller mill equipment, ensure the life-span of Roller of High, improve the operating rate of high pressure roller mill machine equipment.
In whole control system, the circulating load of high pressure roller mill can be fed back to control cabinet by rim charge high pressure roller mill feeding metering device and high pressure roller mill discharge control device, when needs increase circulating load time, the transmission device of the electric rotating plate 16 in hopper 17 starts, inwardly move in the top promoting electric rotating plate 16, by a part, the material originally fed in product is assigned to rim charge and returns on ribbon conveyer 2, then control cabinet provides order, the speed of discharge ribbon conveyer 7 under increase high pressure roller mill returning charge storehouse, increase the ratio returning rim charge in high pressure roller mill feed.When needs reduce circulating load time, the transmission device of the electric rotating plate 16 in hopper 17 starts, outwards move in the top promoting electric rotating plate 16, by a part, the material originally fed in returning charge is assigned in product, then control cabinet provides order, under reduction high pressure roller mill returning charge storehouse, the speed of discharge ribbon conveyer 7, reduces the ratio returning rim charge in high pressure roller mill feed.The combination of rim charge high pressure roller mill feeding metering device and high pressure roller mill discharge control device effectively can control the circulating load of high pressure roller mill to obtain 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 fed 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 fed in feed hopper.High pressure roller mill feed hopper pressure control device of the present invention effectively can control the pressure in high pressure roller mill feed hopper in conjunction with rim charge high pressure roller mill feeding metering device, thus static pressure required when ensureing that high pressure roller mill is broken, ensure to produce and carry out smoothly.
When high pressure roller mill needs maintenance time, 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 it is inner that plate tilts to be inserted into feed hopper 12, until the material in feed hopper 12 stops by two plates.Now control cabinet provides order, and electric gate valve 15 stops.When maintenance terminate rear high pressure roller mill to again operate time, control cabinet provides order, and two electric gate valves 15 start, plate tilt exit from feed hopper inside.The electric gate valve 15 that two inclinations are arranged symmetrically with, feeding flow path direction, valve switch is easier, not easily produces blocking.
The present invention configures rationally, compact conformation, and automaticity is high, and maintenance is little, and operating rate is high, is conducive to ensureing producing carrying out smoothly.
