Metal shredder shredder advantages compared with other crushers characterized by knife shaft speed and low noise, low power consumption, small footprint. Applicable to the recovery of small and medium sized blocks, economical and practical. Make more perfect smash series existing function. Easy to move and place. Tangential inlet without the use of pushers. Common structure shredder shredder structure mainly biaxial (or axis) shear, uniaxial crushing roll with tear-cut style, three. 1) shear shredders The most common is the shear mill, he had two to four qingjian county Paint Bucket tool axis shredder achieve almandine separation, mainly by "cut and cut" principle to complete grinding process. The principle of this mill objects like scissors, like the crush. 2) Cut the roll mill roller mill cut on a rotating blade roll tops plurality of blades, and the formation of cut blade fixed qingjian County Bucket shredder achieve almandine separation to complete material crushing effect . 3) the principle of tearing type grinding mill tear type grinding mill is swinging hook torn waste material. This model is mainly used for coarse crushing. Shaft Shredder for crushing plastics, rubber, fiber, paper, wood, large hollow materials (plastic barrels and other large containers) and a variety of mixed waste especially metal-containing waste, or pre-crushed containing sand and other easy to wear tool waste. For example: film rolls, bags, televisions, refrigerators shell, wood, car and midsize car tires and hollow barrel class, fishing nets, cardboard, board and so on. Thickness and number of claw cutter knife can be replaced according to different materials. When broken hollow material pressing device can be equipped to increase production. Another may be added to control the discharge rotary screen size. When Shaft Shredder low speed operation, noise and dust can achieve higher environmental standards.
