Double roller pellet mill
Working principle
Two rollers rotate in reverse, materials between rollers are compressed, the intermedia products are bar shape / sheet, then the crusher will crush the bar shape products into irregular granules, finally using screen machine to sieve standard products, non- standard products will be recycled mix with new material for the next granulating process.
Advanced driving system
- Adopting increased shafts output dedicated reduce and drum gear shaft coupling effectively protects the rolls and the main bearing from damage, increase the driving efficiency and further improving the production of products. One roller’s bearing seat is fixed and the other roller’s bearing seat is sliding.
- In the surface of the roller, many holes are arrayed. According to the different compression rate of the materials, choose the trough of one roller aiming at the trough of another roller, or peak to trough. Two rollers are arranged in horizon.
- With the supporting pressure of hydraulic cylinder, they are close to each other and the hydraulic system can has the multiple and automatic protection function.The optimized hydraulic system makes the motion flexibility of dynamic rollers stronger and be able to reject the iron lumps mixed in unexpectedly and protect the equipment to run safely.
- Roller pulling with roller removal device, it’s more easily and quickly for you to change the rollers, and save your costs of changing.
