The industrial dust were a kind of dust collected from converters, smelting plants such as steel mill, its main ingredient is iron and carbon, return to sinter it can be pressed into briquettes as raw materials then return to sintering. In general the dust of converter which using the electric dust collector contain iron content more than 50%, Primary dedusting (equipment: evaporation cooling device, role: removing dust, cooling) its dust is rough that can be as raw materials of sintering, directly sintering, The second dedusting (equipment: electrostatic dust collector, role: removing dust and cooling), itsdust is more fine, the part of them can be recycled using as sintering raw materials, making briquettes from the anther part to sintering in vertical furnace. In accordance with the ratio, pressing briquettes has little effect on the quality of mineral products.Traditional steelmaking use damp dusting system, this removing dust is precipitated into the sludge, commonly known as "red sludge", which has full hydration of calcium oxide, pressing into briquettes does not break up easily.
Our converter dust briquette machine is technically designed and produced for briquetting various industry dust, it high productivity, high degree of automation, production efficiency,low failure rate, easy maintenance, so Zhongzhou converter dust briquette machine is welcomed by many enterprises at home and abroad all the time.
Production technical process:
Transporting converter dust to mateials bin through a dust suction car, after digesting, then go into the mixing machine and blend with binder then press into briquettes by a hydraulic briquette machine, the briquttes can be dried by our vertical dryer or using your industrial exhaust, finally sieve them to get qualified product.
After many years of practical experience, has successively carried on the transformation to hopper, crusher, mixer, briquette machine, at present our proposal of dust briquetting project can basically achieve 100% production of dust briquettes.
The main compsed equipment for converter dust briquettes production:
1, Hopper silo, uniform quantitative material to the horizontal two-shafts mixer.
2, Blender,also named liquid mixer, it is used for liquefied adhesive (if you use powdered adhesives, you can choose the dry powder feeder.)
3,The horizontal two-shaft mixer, full mixing raw materials, adhesives, water. The adhesives should uniform distribution among raw materials in order to achieve better thermal strength, briquettes is hard and better.
4, converter dust briquette machine is the core of whole production line, it press mixing 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 from briquette machine,the briquettes can be drying to 3% water content, finished briquettes will put in storage or packaged.
7, belt conveyor, connected to devices, it is guanrantee for the whole converter dust briquettes production line to realizes full automation.
The requirements for raw materials of converter dust briquettes production:
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 pressure equipment technical services, to create maximum value for clients, The converter dust briquette machine produced has the high pressure, high finished product rate, high strength, fully meet the requirements of the operation of converter steelmaking, cost reduction for the production practice of converter smelting, optimized operation,shorten the smelting practice, 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.
