Double Roller Extrusion Granulator
The Double Roller Extrusion Granulator is a commonly used device for producing graphite particles. It applies pressure and extrusion to the graphite raw materials through the rolls of a press, transforming them into a granular state.
The general steps and process of producing graphite particles using a Double Roller Extrusion Granulator are as follows:
1. Raw material preparation: Preprocess the graphite raw materials to ensure appropriate particle size and free from impurities. This may involve steps such as crushing, grinding, and sieving.
2. Feeding system: Transport the preprocessed graphite raw materials into the feeding system of the Double Roller Extrusion Granulator. The feeding system typically consists of a conveyor belt, screw structure, or vibrators to achieve uniform and stable material supply.
3. Pressing and extrusion: Once the raw materials enter the Double Roller Extrusion Granulator, they undergo pressing and extrusion by the rolls of the press. The rolls are usually made of metal and may have textured or uneven surfaces to increase pressure and enhance the extrusion effect on the materials.
4. Particle formation: During the pressing and extrusion process, the raw materials gradually form graphite particles. The granulator typically has multiple pairs of roll grooves, causing the materials to roll back and forth between the grooves, further promoting particle formation.
5. Cooling and solidification: After particle formation, cooling and solidification may be necessary to ensure the stability and firmness of the particles. Cooling can be achieved through natural cooling or by using a cooling system that provides a cooling medium.
6. Screening and grading: The produced graphite particles may require screening and grading to obtain the desired particle size and grading.
7. Packaging and storage: Finally, the graphite particles are typically packaged and stored for transportation and use. https://www.yz-mac.com/roll-extrusion-compound-fertilizer-granulator-product/
