First. Introduction to Roller Granulator

The double-roll granulator is a molding equipment that makes materials containing a certain amount of moisture into a specific shape. It is mainly composed of a frame, a fixed roller device, a movable roller device, and a transmission device. Its working process is to extrude the material entering the double-roll granulator into shape at one time. The machine has the advantages of reasonable structure, stable and reliable performance, convenient cleaning and maintenance, low energy consumption, long service life and high granulation rate.

Second, the working principle of the roller granulator

The working principle of the double-roller granulator is that the motor uses the belt to drive the reducer, and the reducer drives the fixed roller and the movable roller to rotate synchronously through the chain transmission. The material falls between the paired rollers from the top of the equipment, is squeezed by the double rollers, granulated, and discharged from the discharge port. The function of extrusion is to squeeze out the air between the particles, and to make the distance between the particles close enough to generate attractive forces such as van der Waals force, adsorption force, crystal bridge and embedded connection. Extruded granulated particles mainly rely on the strength of particles formed by the force between molecules.

Third. Structural characteristics of the roller granulator

3.1  The integrated welding and processing frame ensures the processing, matching accuracy and shape tolerance of each part, and effectively improves the installation accuracy and reliability of the whole machine.

3.2 Belt transmission is used between the motor and the reducer, the transmission is stable and reliable, and the motor has overload protection function

3.3 The movable roller device can adjust the pre-pressure of the movable roller device by adjusting the position of the bearing seat, so as to obtain the product that meets the requirements.

3.4 The split structure of the drum and the hub makes it easy to replace the drum.

Fourth. Advantages of double roller granulator

4.1 Since the raw materials are extruded during the granulation process, the initial strength of the produced product is relatively high.

4.2 The particle size of the produced product is uniform.

4.3 Low equipment investment and small footprint.
