We're here to help: Easy ways to get the answers you need.
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 / briquetting 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 Direct reduction iron DRI briquette machine briquetting machine was welcomed by many enterprises at home and abroad.
Here we focus on the briquetting part in the Direct Reduced Iron production process, the DRI Briquettes production process generally include batching, grinding, mixing, briquetting 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.
The requirement for raw materials of direct reduced iron briquette machine:
|Power||7.5 kW||11 kW||18.5kW||22kW||37kW||55kW||90 kW||110kW|
|wear-resistant alloy||wear-resistant alloy||wear-resistant alloy||wear-resistant alloy|
|Roller assemble||Split-clamp type||Temper assembly||Temper assembly|
|Hardness of roller||52-62 HRC||52-62 HRC||52-62 HRC||52-62 HRC||52-62 HRC||52-62 HRC||52-62 HRC||52-62 HRC|
|Pressure structure||Four-rollers double pressure||Four-rollers double pressure||Four-rollers double pressure|
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.
National standard bearing
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.
