Double roller fertilizer press machine

 Wee can design different kinds of granulating process asscording to your requirements.

Working Pinciple 

Two rollers rotate in reverse, materials between rollers are compressed, the intermediate products are bar shape / sheet, then the crusher will crush the bar shape products into irregular granules, finally using the rotary screen to sieve standard products, non- standard products will be recycled mix with new material for the next granulating process.

Summary

• Offers higher bulk specific gravity. (Materials can be processed without being bulky.)
• Maintains stability of bulk specific gravity.
• Improves liquidity. (It facilitates constant feeding, weighing, and others.)
• Eases the system handling.
• Prevents materials from scattering (i.e., improves the working environment).
• Facilitate mixing of materials.
• Provides smooth melting of materials (in other words, hardly forms lumps of materials).

Unit structure

1)  Pre-feeder: Equipped with mechanical vibrating feed hopper with automatic control and timing vibration

2)  Quantitative feeder: Adopts frequency conversion adjusting speed to ensure the feeding accuracy.

3)  Force-feeder: It is composed of variable frequency motor, cone helix, stirring knife tooth and cone feeding hopper with visual glass window as well as feeding mouth assemblies and so on. Its function is to further achieve degassing and perform pressure feeding.

4)  Flaking machine: it is composed of left and right fixed bearing seats, frame structure, two alloy steel rollers, two hydraulic oil cylinders, electric automatic pump station as well as hard tooth surface dedicated reducer and main driving motor.

5)  Crusher: it is composed of cutting-up box, cutting-up main shaft and special rotating cutting blades and the main shaft is driven at high speed by the motor to break the extrusion forming materials and dress into pellets.

6)  Vibration sieve: It is equipped with screen block-proof device and convenient to clean the screen. The broken pellet and powder materials from the breaking and dressing machine is divided into pellet product and recycling powder.

 7)  Screw conveyor for recycle: It sends the unaccepted powder material returned from vibration classification screen to the feeding elevator.

8)   Bucket elevator: HLType, used for feeding materials.

9)   Control cabinet: It is composed of the electrical components such as electric control box, frequency conversion controller, ammeter, voltage meter, light, button switches, voltage switch and so on. All the electrical equipment is controlled and operated concentratedly.
