Single-shaft shredder is a common equipment used for waste treatment and recycling, mainly used to shred, shred and shred all kinds of waste (such as plastic, paper, metal, wood, etc.). The blade is one of the core components of the single-shaft shredder, and the selection of the right blade is the key to ensure the normal operation and efficient operation of the equipment.
The principles and methods for selecting single-shaft shredder blades are as follows:
Material selection: The material of the blade directly affects the service life and crushing effect. In general, the commonly used blade materials are high-quality alloy tool steel, cemented carbide, etc. High-quality alloy tool steels have high hardness and wear resistance, which can maintain the sharpness of the blades during the crushing process, while also providing a long service life. Tungsten carbide inserts are harder but more brittle, making them suitable for use in situations where the hardness of crushed materials is high. Choose the right blade material according to the material.
Blade shape: There are two main shapes of single-shaft shredder blades: strip blades and claw blades. The strip blade is suitable for shredding soft materials, such as paper, cellulose, etc., and has a large cutting area;The claw blade is suitable for crushing hard materials, such as plastic, metal, wood, etc., with better targeting and crushing effect. Choose the appropriate blade shape according to different crushed materials.
Blade size: The size of the blade is also an important factor in selection. The length and width of the blade should be determined according to the specifications of the crusher and the requirements of the material. Generally speaking, the longer the length of the blade, the better the cutting effect, but the excessively long blade is easy to cause the equipment to overload and the motor to overheat, affecting the stability of the equipment. The width of the blade also affects the cutting effect, and the appropriate width can provide a large cutting area and improve the crushing efficiency.
Insert fixing: The fixing of the blade to the spindle is also an important consideration in the selection. Common fixing methods include screw fixing, tool holder fixing, etc. The screw fixing method is simple and easy, but it is easy to loosen and deform in long-term use, and needs to be checked and adjusted regularlyThe toolholder is fixed in a firmer way to provide better stability.
Lessons learned and expert advice: When choosing blades, you can learn from the experience and expert advice in the industry, especially those companies that already use the same type of equipment. Their experience and opinions can provide some constructive ideas and suggestions for the selection of blades, and improve the accuracy of blade selection.
