Fertilizer pelletizer machine

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. Then we get the round shape granular, but in order to get the better results, we suggest using a rotary screen to sieve the final products, qualified products will be put into bags, and unqualified products will be recycled mix with new material for the next granulating process.

A completely dry granulating 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

Technical parameters

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

 Advantages of Fuyi 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.
