Direct reduction iron(DRI) also named sponge iron, It is the raw material for electric furnace steelmaking. In the direct reduced iron production process, no matter what kind of production process is, all need use briquette machine to complete briquetting raw materials, mixing all materials such as iron ore, iron concentrates, coke, coal and bidner together, to press them into briquettes by briquette machine, then remove moisture, the drying briquettes can be smelted in furnace.
Zhongzhou briquette machine is specifically designed for briquetting in DRI production process, it is high pressure, high product rate, working stably,low failure rate and easy maintenance, so Zhongzhou spong iron briquette machine was welcomed by many enterprises at home and abroad.
Here we focus on the briquetting part in the Direct Reduced Iron production process:
Briquettes process generally include batching, grinding, mixing, pressing and drying.
1. Hopper silo, or box type quantitative feeder, it load and convey raw materials to crusher evenly.
2. Two-stage crusher, the raw material be crushed in to the appropriate size, generally it is most suitable that not more than 5mm.
3. Liquid mixer, be used for mixing liquid binder, if use powdered binder, it should use a drying powder feeding equipment.
4.Horizontal two shafts mixer, evenly mixing raw materials, adhesives andwater together, the adhesive will be evenly distributed in the raw materials so that achieve better strength, making briquettes better.
5. carbon silicon briquette machine is a core of whole production line, it press materials into briquettes, the briquettes' size and shape can be customized, zhongzhou can produce various shapes of rollers.
6, vertical dryer, drying the wet briquettes which came from briquette machine,the briquettes can be dried to 3% water content, finished briquettes will put in storage or packaged.
7, belt conveyor, connected to devices, it is guanrantee for the whole manganese ore briquettes production line to realizes full automation.
1, the particle size of the raw material should be between 0-5mm.
2, can not contain impurities, especially large metal. Such as nails, or iron, rocks, it very likely damage roller and spindle..
3, the feeding of whole produciton line should be stable, even, ensure workloads of briquette machine stable, to get high efficiency of production.
Zhongzhou company based on metallurgical briquette press equipment technical services, to create maximum value for clients, Direct Reduced Iron briquette machine we produced has the high pressure, high finished product rate, high strength, fully meet the requirements of the operation of steelmaking, cost reduction for the production of smelting, optimized operation,shorten smelting practice term, speed up the rhythm of steel making, create the conditions for the realization of maximum benefit, we sincerely welcome all steel enterprises to explore, mutual benefit and win-win.
