Secondary shredder GF series

Four-Shaft shredder is a multi-purpose shredder, it has the same working principle as two-shaft shredder. GF Series four-shaft shredder can control the final material size by equipping a screen at the outlet. Four-shaft fine shredder provides greater shearing force than two-shaft shredder, it can handle all kinds of toughness, ductility of waste materials and obtain consistent shape and size. APPLICATION In general, four-shaft shredders are used for more difficult tasks, such as reducing large volumes of material to a small and uniform size in a single pass, while maintaining good throughput. The function of the two cutters above the four-shaft shredder is to clean the shafts below and at the same time provide a certain amount of shearing force. WORKING PRINCIPLE The GF Series four-shaft shredder has four sets of shear rolls with different tool configurations to match each other. Once inside the shredding chamber, the material is shredded into small pieces by the tearing and shearing action of the blades on the four sets of rolls. The size of the output material is controlled by the screen. After the material is cut once, the material with a smaller particle size than the hole of the screen is discharged from the lower part of the box under the action of gravity and squeezing pressure, while the material with a larger size than the hole of the screen is guided by the main cutters and the secondary cutters to return to the inner surface of the screen for the second cutting, and so on until the material can be discharged from the hole of the screen.
