We're here to help: Easy ways to get the answers you need.
The blast furnace sludge is the waste of blast furnace ironmaking.In the blast furnace ironmaking process, impurities in iron ore, such as lead and zinc were restored, and to form steam at high temperatures, with ore, coke, fluxes and blast furnace gas was brought outside, then through the furnace gas dust purification system to catch removed. Coal gas gravity dust and fine dust of the dust removal system composed of two segments, the trap down in the first paragraph of the coarse particle dust dry is heavy dust; the second paragraph of fine dust and dry type bag filter or wet cleaning system. The drying type dedusting of drying fine-grained dust been known as bag filters dust (blast furnace dust, fine dust), The wet dust that obtained after precipitation treatment sludge been known as blas furnace sludge.Blast furnace sludge primarily composed of iron oxide and carbon, also contains a small amount of zinc, bismuth, lead etc nonferrous metal. The blast furnace sludge/dust recycling, not only enable the valuable mineral resources To recycle, you can also reduce the dust pollution to the environment.
After numerous experiments, the blast furnace sludge/dust mix the sintered ore then briquetting by blast furnace sludge briquette machine,briquettes can be sintered in furnace, making full use of iron and carbon in sludge, to reduce energy consumption,reduce the cost of sintering.In addition, the blast furnace dust without additional processing, you can use the cheap coal as reducing agent and fuel, through briquetting by high pressure briquette machine, directly smelting on the furnace, it can be obtained more than 90% of the direct reduction iron.
Blast furnace gas sludge is mixed with iron ore concentrate powder and some binder, as 0.8 : 1 : 0.018 ratio, blend then go into high pressure briquette press machine to briquetting, the briquettes produced can roast in furnace The roasting temperature is 1330-1360 ℃, 50-60min roasting time, under the condition of 30-40mm fabric thickness, it can reach TFe75%-80%,MFe 60-70%, MR80-90%,C1-2%, S0.50%-0.60%. Zhongzhou blast furnace sludge briquette machine is specifically designed for briquetting blast furnace sludge etc powdered materials, it has high productivity, high degree of automation, production efficiency,low failure rate, easy maintenance, so Zhongzhou blast furnace sludge/dust briquette machine was welcomed by many enterprises at home and abroad.
Zhongzhou company based on metallurgical briquette press equipment technical services, to create maximum value for clients, The blast furnace sludge briquette machine we 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.

Four rollers double pressure
after the first pressurization, the materials between main and auxiliary rollers enter the place between two main rollers for a second pressurization, where the pressure will be twice of the type of two rollers.(the auxiliary roller pre-press the hemisphere on the amin roller to exhaust air, the hemisphere will be pressed again into briquettes fomation through two main rollers).
GB standard hydraulic components
manufaturing by Dezhou oil pump company, using embolism type pump equipped with storage device which can be operation of protection briquette machine when the hydraulic moment fluctuation, the oil cylinder adopts compound type and be made of standard material 27SiMn, extremely good finish, wear resistance, having protective effect on seals.
Roller taper assembly techology(patent)
Roller and wheel hub of briquette machine is processed into tamper structure, which shall be compacted firmly by bolts for stability and reliance, easy to replace roller,save time and efforts for users.
9Cr2 forging rollers
the roller materials adpot 9Cr2 forging steel, high precision and abrasion resisitant, the rigidity reach to 55-60HR through prempering.

Using the rolling mill bearing series, each model is the double row cylindrical ball bearing, well-known brands, lagre load bearing, stable performance, guarantee period of 5 years.
Split plummer block
Unique split type design, precision machining, simply remove the bolts when the user maintenance, open housing, can be seen bearing, ease of maintenance.
Independent production, full steel material bell housing, gears made of 40Cr steel, stable performance.
high quality finished No.45 steel tempering.
15 ton Coal Briquettes Production Plant in Congo
In March, 2016, our coal briquettes production plant was exported to Congo. This briquette plant includes coal briquette machine, crusher, double shaft mixer and binder mixer.
One set rotary dryer shipped to Vietnam
Rotary dryer is mainly applied to drying river sand, dry-mixed mortar, yellow sand, cement clinker, clay, coal gangue, mixtures, coal ash, gypsum, iron powder and other raw materials, widely used in building materials, chemical industry, casting industry and other industries.
One set coal briquette machine shiped to Lagos
Coal briquette machine can press coal powder, coke powder, coal gangue, and fly ash into ball shape. It not only reduces energy consumption, but also promotes the sustainable development strategy.
The production field in Indonesia north
Coal is the applicable and energy,so if waste the coal,it will be wasteful.So some people think that we can press coal into briquettes to storage for storage,thus coal is made full use and save energy,improve efficiency.Atthe same time,we need one machine to press coal into balls.Henan Kefan is the professional coal briquette machine supplier in China,we can supply other briquette makers,such as charcoal powder briquetting machine,etc.We can supply best products and best service,and customers who have brought our products all over the world give our products high praise.
