Sponge iron also named direct reduction iron(DRI), It is the raw material for electric furnace steelmaking.In the sponge 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 sponge iron briquette machine is specifically designed for briquetting in the sponge iron production process, it  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 sponge iron production process:

• Briquettes process generally include batching, grinding, mixing, pressing and drying.
•  Hopper silo, or box type quantitative feeder, it load and convey raw materials to crusher evenly.
• Two-stage crusher, the raw material be crushed in to the appropriate size, generally it is most suitable that not more than 5mm.
• Liquid mixer, be used for mixing liquid binder, if use powdered binder, it should use a drying powder feeding equipment.
• 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.
• 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.
• 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.
• belt conveyor, connected to devices, it is guanrantee for the whole manganese ore briquettes production line to realizes full automation.

•  the particle size of the raw material should be between 0-5mm.
•  can not contain impurities, especially large metal. Such as nails, or iron, rocks, it very likely damage roller and spindle..
•  the feeding of whole produciton line should be stable, even, ensure workloads of briquette machine stable, to get high efficiency of production.

 Productive advantages

• 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.

• Steel reducer

  

  Independent production, full steel material bell housing, gears made of 40Cr steel, stable performance.

• Spindle material

  

  high quality finished No.45 steel tempering.

  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.
