What is the working principle of the double roll granulator

The working principle of the roller granulator is mainly based on the extrusion and forming process of the material by two relatively rotating roller shafts. Specifically, its working principle can be summarized as follows:

Equipment structure

The roller granulator is mainly composed of two parallel installed roller shafts, transmission system, adjustment system, and chassis. The roller shaft is equipped with a roller surface, and the material of the roller surface can be selected according to the properties of the manufactured particles to adapt to the characteristics of different materials.

workflow

• Material addition: Add powdered material into the roller granulator from above.
• Squeezing: Under the squeezing of two rollers, the powdered material is compacted, bonded, and gradually formed into particles. When the roller shaft rotates, the particles are continuously squeezed between the roller surfaces, and the particles gradually increase until they reach the desired size.
• Adjustment control: By adjusting the system, the pressure and speed of the roller shaft can be controlled to produce particles with the required size and density. This step is crucial for ensuring particle quality.

Key technical points

• Dry extrusion: The roller granulator adopts a dry extrusion process, which does not require the addition of additional adhesives or wetting agents, and relies on the intermolecular forces of the material itself for molding. This method simplifies the production process and reduces energy consumption.
• Precise control: By adjusting the clearance and speed of the roller shaft, precise control of particle size and density can be achieved to meet the production needs of different products.
• Wide adaptability: The roller granulator is suitable for various materials, including raw materials from industries such as pharmaceuticals, food, chemicals, ceramics, etc., and can produce high-quality granular products.
