Disc feeder

Cold ore belt sintering machine is the most widely used sintering machine in China's small and medium-sized iron making enterprises. Its technology is advanced, reliable and practical, and the process is applicable: it is mainly applicable to the sintering treatment of iron ore powder in medium and small-scale smelters. Performance features: annular operation sintering, advanced process design, high efficiency and continuous operation, equipped with centralized lubrication system to ensure safe operation of the equipment. 1. Proportioning system proportioning system is composed of proportioning bin, disc feeder, proportioning belt conveyor, etc. Concentrate powder, rich ore powder, fuel, flux, return ore and other materials are loaded into the bin of the proportioning room by loader. The above materials are sent to the proportioning belt conveyor according to the required proportion by disc feeder, and then transported to the cylinder mixer by belt conveyor for mixing and pelletizing
2. Mixing granulation system: the mixing system is generally completed by secondary mixing. The primary mixing is mainly to evenly mix all kinds of materials from the batching room, and then send them to the secondary mixing pelletizing system by belt conveyor. The secondary mixing is mainly to improve the pellet quality and improve the air permeability in the sintering process. The mixture is made into a small spherical mixture of 3-8mm, accounting for 75%, The drum mixer has the advantages of wide mixing range, adapting to the change of raw materials, simple structure, reliable proction and large proction capacity
3. Mixture distribution system: the mixture distribution system is mainly composed of round roller feeder, reflecting plate and fan gate. According to the process requirements, the mixture is supplied to the reflecting plate for segregation distribution by adjusting the opening degree of the fan gate and the rotating speed of the round roller feeder, and different distribution effects are obtained by adjusting the angle of the reflecting plate
4. Gas ignition system: the gas ignition system consists of gas and air conditioning system, burner, combustion fan, ignition chamber, etc. The gas ignition system adopts blast furnace gas. The igniter uses its own preheating device to preheat the combustion air. The temperature of combustion air can be increased by 100-150 ℃, and good energy saving effect can be achieved< Sintering machine: the main system of sintering machine is mainly composed of transmission device, head and tail end seal, trolley bellows, suction device, frame, st falling system and st collection system. The main drive mechanism is set at the side of the lower part of the large plate, which is composed of motor, recer, turbine recer, etc. the normal operation of the equipment is guaranteed through the cooperation of ordinary recer and turbine recer. The tripper adopts 3KW motor, which is located at the tail of the large plate. The independent power system completes the unloading of the large plate. The trolley is closely linked with the bellows, and there is no gap to effectively prevent air leakage
6. Crushing and screening system of ore deposit: the double toothed roll crusher is installed at the tail of the sintering machine, which is mainly responsible for unloading the trolley, crushing the large ore deposit into small pieces, and hot screening the sinter crushed by the double roll crusher, so as to separate the finished proct and the return ore (for hot ore proction process); Or in order to improve the cooling effect (for the cooling ore proction process). Sintering ore ≥ 5mm is transported to phosphorus plate conveyor through chute, and then transported to ore storage tank by belt conveyor for blast furnace& lt; 5mm powder is transported to the mixing system room through the belt conveyor under the screen for mixing and sintering again
7. Exhaust st removal system: the exhaust st removal system consists of st pipe, cyclone st collector, gravity st collector and water st collector. It is composed of main exhaust fan, pipeline and chimney. The flue gas and st generated in the process of sintering exhaust and the exhaust gas and st (st is about 0.5-3g / m3) generated in the process of exhaust cooling enter the st pipe through the air box, and the st pipe (above 50mm) is removed. The flue gas and st after st removal enter the gravity st collector for secondary st removal, The st is discharged to the transport car through the ash discharge valve of the st collector and transported to the material bin of the batching room to participate in the batching. After gravity desting, it can reach the national emission standard after Cyclone and water curtain desting
8. Cooling system: the main cooling methods of sinter are blast cooling, exhaust cooling and on-board cooling. The belt cooler is mainly composed of chain, trolley, transmission device, tension device, seal and fan, and is installed with two forms of inclined and horizontal plane. Generally, the inclination angle of cooler is less than 80. The ring cooler mainly includes trolley, rotary frame, guide rail sliding frame drive device, belt conveyor and belt conveyor It is composed of feeding and discharging device, bellows (or smoke, etc.) sealing device, discharging device, fan, etc. Cooling effect of sinter: the finished proct is uniform, which can strengthen the blast furnace smelting, increase the top pressure and increase the pig iron output

As the name suggests, the main function of disc feeder is to provide material supply for other equipment. The use of disc feeder can make the material evenly enter a equipment, so that the next process can work normally, save labor, protect the performance of the equipment, and extend the service life of the whole proction line equipment. Disc feeder is an indispensable proct of mineral processing equipment

Crushers: jaw crusher, hammer crusher, impact crusher, cone crusher, toothed roller crusher, double roller crusher, etc. Ball mill: Superfine laminated autogenous mill, cement ball mill, cone ball mill, ceramic ball mill, energy saving ball mill, high energy ball mill, high fine ball mill, lattice ball mill, overflow ball mill, etc
