Roller shell plays an important role for granulator. Customized Roller Shell, Casting Steel Roller Shell can be found on our website. A feeding system with a combination of a pre-continuous feeder with a mechanical vibratory device and a forced-feed screw hopper ensures the continuity, adequacy and uniformity of feeding, which is a crucial step. The roller granulator engraves the uniform arc groove on the pair of rollers, which is beneficial to the material biting into the roller, forming the arc groove sealing chamber (band) during the work, and also conducive to the compaction of the material, reducing the forming pressure of the unit and the host The load improves the productivity of the pellets. The roll granulator is also equipped with automatic pressure compensating and pressing device for rolling sheet forming hydraulics, sight glass and so on. After the powdery material passes through the bucket elevator, the entire process can be completed in one go from feeding, screw degassing, rolling, chopping, and sieving to granular products, which can be used to raise rabbits, chickens, ducks, geese, fish, etc. Pigs, aquatic products and so on.
