Dry Roll Press Pelletizer

Product Description

The importance of powder pelletizing technology as one of the most important branches of powder particles processing treatment is increasingly clear with the demand of environment protection and the improvement of automation of the production process. "Powder product palletizing" has become the necessary trend of powder-after-processing technology in the world.
Operation of the roll press adopts on-line control technique. It can conveniently and visually set working parameters, online testing and controlling the operation state of the equipment, and provide real time determination information to the control personnel. With its help, our roller press pelletizer works more stably.
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.
