1.Features Shredder knife and blade is one of the most important parts of shredder, the quality of shredder blade directly affects
the processing cycle of mechanical scrap, according to the classification of shredder, shredder blade is divided into single-axis shredder blade and multi-axis shredder blade.As an important shredding tool for shredding machines. According to the shredder structure classification, the shredder blade can be divided into single-axis shredder blade, multi-axis shredder blade (including two-axis shredder blade and four-axis shredder blade).
2.Shredder blade is divided into fixed knife and moving knife, fixed knife through the internal hexagonal hole fixed on the main shaft of the shredder material crushing processing.The single-spindle shredder blade, as the name implies, is installed on the shaft of the single-spindle shredder, by called the moving knife.The shape is square, the edge is curved on all sides, and the tapping hole is in the middle. The part from the edge to the middle hole is concave inward, which can be used with the fixed tool on the tool rest.Multi-axis shredding machine blade for claw, according to the design of each company, shredding machine installed in biaxial or four axis, generally can be divided into three claw shredding machine blade, 8 claw shredding machine, 12 claw shredding machine blade, etc, used for crushing, tearing and extrusion to decrease the size of the material, the shredding machine blades are widely used in waste plastics, waste rubber, wood and other large volume of waste. 3.Blade material Manufacturing shredding machine blade material for 9 crsi commonly, Cr12MoV, SKD - 11, 9crsi ,H13 , D2 and other alloy tool steel, the material cutting tools high hardness, good wear resistance, but the brittleness is larger, apply to rubber, fiber, paper and other soft material waste, Cr12MoV and SKD - 11 for cold work die steel, the two kinds of material performance, with strong abrasion resistance, impact resistance is strong, suitable for shredded
