Shredder machine and shredder blade
Shredder blade is one of the most important parts of the shredder, shredder blade is good or bad directly affects the processing cycle of the mechanical waste, according to the classification of the shredder, shredder blade is divided into single-axis shredder blade and multi-axis shredder blade. As an important shredding machine crushing operation knife. According to the classification of shredder structure, shredder blades can be divided into single-axis shredder blades, multi-axis shredder blades (including two-axis shredder blades and four-axis shredder blades).
The single-axis shredder blade, as the name suggests, is mounted on the shaft of the single-axis shredder, which is called a moving knife. The shape is square, the four sides of the knife edge are curved, the middle tapping hole, the part from the knife edge to the middle hole is concave inward, and the tool is used with the fixed tool on the tool holder.
Multi-axis shredder blade for claw knife, according to the design of various companies, installed in the two-axis or four-axis shredder, generally can be divided into 3 claw shredder blade, 8 claw shredder knife, 12 claw shredder blade, etc., used to crush, tear and extrusion to reduce the size of the material, this shredder blade is widely used in waste plastic, waste rubber, wood and other large volume of waste crushing.
Shredder blade material is generally 9crsi, Cr12MoV, SKD-11, of which 9CrSi is alloy tool steel, this material tool hardness is high, wear resistance is good, but brittleness is larger, suitable for rubber, fiber, paper and other materials soft waste, Cr12MoV and SKD-11 for cold work die steel, These two materials have similar properties, strong wear resistance, strong impact resistance, suitable for shredding wood, waste furniture, high hardness of plastics and so on.
