Carbon black pellet machine  

      Fuyi offers a proven range of machine sizes for high pressure granulating, which covers nearly all requirements of the clients.  

Working principle  

     Raw materials are sent into hopper by fixed quantity feeder, when two rolls parallel each other horizontally, powder materials are continuously and evenly fed in the gap between two rollers by their gravities and forced compression, The intermediate products are bar shape, then the crusher will crush the bar shape products into irregular granules, finally using rotary screen to sieve the final products, qualified products will be put into bags, unqualified products will be recycled mix with new material for the next granulating process.

A completely dry extrusion process includes the following equipments  

1. Automatic feeding system 

2. Auto-measuring batching and mixing system 

3. Extruding and pelletizing system 

4. Complete pellet smashing system 

5. Screening and materials returning system 

6. Auto-packaging and control system 

7. Dust collector system 

Examples of extrusion materials 

1. Fertilizers:  

     potassium sulfate(SOP), potassium chloride, the Russian red potassium, NPK fertilizer, ammonium chloride, potassium nitrate, Ammonium Phosphate Monobasic(MAP), Diammonium phosphate(DAP), ammonium sulfate, ammonium bicarbonate, cow manure plus sulfur, humid acid etc. 

2. Powders:  

     zinc oxide,Bentonite, benefication agent, phosphate rock, aluminum fluoride Calcium Hypochlorite, calcium chloride, calcium phosphate, cryolite, TSP, SSP, antioxidant, potassium carbonate, rubber additives, metal powder, fillers, feed additives, silica, pharmaceutical intermediates, steel-making additives, lead oxide, melting agent, clay , steelwork dusts, etc. 

3. Carbon Black / Graphite 

4. FGD gypsum 

5. Chemical powder: Sodium formateHCOONa, Magnesium acetate. 

Rollers available in various materials and Final shape granular   

Technical parameters  

Notice: Rolled sheet output, finished product output is reference values and the screen is determined according to the nature of the materials. 

Latout of Fuyi briquetting Presses  

     Powder are entered into a roller press and compacted between the rollers to a strip with high density. 

     We can design different diagram for different clients, we need to design the layout according our clients provide us some basic information about the size of their factory, and how do they want to place the equipments. Our target is making the process more simple , more easy, more economic and more effective.  

Roller presses 

      During press a granular, material is compacted between two counter-currently rotating rolls. Forming of briquettes is without any binding agent. 

 Advantages of NPK granulator   

     Adopting increased shafts output dedicated reduce and drum gear shaft coupling effectively protects the rolls and the main bearing from damage, increase the driving efficiency and further improving the production of products. One roller’s bearing seat is fixed and the other roller’s bearing seat is sliding.  

    In the surface of the roller, many holes are arrayed. According to the different compression rate of the materials, choose the trough of one roller aiming at the trough of another roller, or peak to trough. Two rollers are arranged in horizon. 

    With the supporting pressure of hydraulic cylinder, they are close to each other and the hydraulic system can has the multiple and automatic protection function.The optimized hydraulic system makes the motion flexibility of dynamic rollers stronger and be able to reject the iron lumps mixed in unexpectedly and protect the equipment to run safely. 

    Roller pulling with roller removal device, it’s more easily and quickly for you to change the rollers, and save your costs of changing.
