Phosphogypsum is the industrial waste residue of phosphoric acid or phosphate fertilizer industry and some synthetic detergent industry, can be used as cement retarder, and at present the government promote energy conservation and emission reduction, waste residue utilization, conservation of resources, environmental protection and other policies. Now the cement plants use phosphogypsum gypsum instead of natural gypsum as the cement retarder.

Zhongzhou phosphogypsum briquette machine  will directly press phosphogypsum into 20-80mm round briquettes and without any adhesive, and the production rate above 95%, the hardness of briquettes pressed is very strong, should not be easily broken when handing and loading, and then supplied to the cement plant using retarder instead of natural gypsum, phosphogypsum briquettes product purity guaranteed, direct forming and into briquettes, high strength, suitable for all kinds of transportation, improve product transportation capacity; phosphogypsum briquette machine has the advantages of compact structure, convenient maintenance, simple operation, short process, low energy consumption, low failure rate, the main part rollers adpot materials 9Cr2 steel forging, greatly improved the wear resistance and pressure resistance, so the whole machine has a long service life.

Zhongzhou phosphogypsum gypsum briquette machine according to the customer's demands to provide the following process:
Project 1. phosphogypsum--- hopper silo--- press machine---briquette machine---final briquettes product
Project 2. phosphogypsum--- hopper silo--- rotary dryer----press machine---briquette machine---final briquettes product
Project 3. phosphogypsum--- hopper silo--- rotary dryer----press machine---briquette machine---vertical dryer---final briquettes product
Project 4. phosphogypsum--- hopper silo--- rotary dryer----press machine---briquette machine---turning dryer---final briquettes product

Phosphogypsum briquettes production supporting equipment are as follows:
1. Gypsum powder: a waste produced in the desulfurization system, can be used as cement retarder
2. Special gypsum feeder: control of the whole production line, solve with gypsum wall not falling, not continuous and uniform feeding, ensure special equipment for drying machine feeding uniform.
3. Rotary dryer: the water is higher than 12% of phosphogypsum be dried to below 8%-10%, easy to pressing briquettes.
4. Press machine: press phosphogypsum more solid, increase the density of gypsum, a kind of auxiliary equipment. Press machine improve the briquetting rate of phosphogypsum, the characteristics is as following: It works for loose materials that not easy to be formed , Pre exhaust and compaction, make materials be briquetted easily, the machine assembling reasonable ,compact structure, stable operation, reliable performance.
5. Phosphogypsum briquette machine/brqiuetting machine: press gypsum into briquettes without any binder, the production rate more than 95%.The final briquettes are more hard, can keep the shape when loading and unloading in transportion. Product purity guaranteed.
6. Turning dryer: it is to drying gypsum briquettes below 3% water content. The gypsum briquettes is evenly placed in the net, through the hot air drying to complete drying task.
7. Vertical dryer: It also can be used for drying final briquettes, the gypsum briquettes was put into the top of dryer by belt conveyor, and in the process slow down, the hot air bring the water of briquettes, quickly be dried to 3% moisture, this machine has small area, easy operation and low maintenance cost.

Zhongzhou company based on phosphogypsum briquette machine/brqiuetting machine  technical services, to create maximum value for clients, The phosphogypsum briquette machine/brqiuetting machine has the high pressure, high finished product rate, high strength, fully meet the requirements of the operation of lime production, cost reduction for lime production, optimized operation, create the conditions for the realization of maximum benefit, we sincerely welcome all enterprises to explore, mutual benefit and win-win!

 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.
