Specifications
Dry Roller Compactor:
1)main depend on double roller
2)moisture requirement:<1%
3)irregular particle(size:2-4mm
Pelletize mill for NPK fertilizer
Working Principle
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.
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-feeding screw hopper: 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) Slice mill: The mainframe of the slice mill 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) Breaking and pellet dressing machine: The breaking and pellet dressing chamber 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 classification screen: 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) Material return screw: It sends the unaccepted powder material returned from vibration classification screen to the feeding elevator.
8) Bucket elevator: HL250 Type, used for feeding materials.
9) Electric 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
