• Two similar productivity shredders, single shaft shredder and double shaft shredder, how do we select?

  Jun 30, 2025

  The difference of two shredders is the power shredding system. A single shaft machine with only one shredding shaft in the middle, rotating to shred items. The double shaft type shreds waste using two rotating shredding shafts. Then, is the dual axis shredder one better than the single axis shredder one in yield volume? Not that really. It also depends on： The power of two shredders The material used to make the blades in the two machines How blades are arranged on the rotating shaft Different waste materials to shred The required size of shredding waste Therefore, the most effective approach for us is to conduct comprehensive testing of the two different shredders, ensuring we make the best selection for our needs.

• What are the reasons that affect the service life of the cutting tools in shredder equipment?

  Jan 30, 2025

  As a crucial component of the shredder machine, the service life of the cutting tools is not just a matter of maintenance; it has a significant influence on the overall performance and efficiency of the shredder equipment. A longer service life of the cutting tools benefits reduced downtime, increased productivity, and lower maintenance costs.   Shredder equipment is a versatile tool capable of shredding and shearing a wide range of materials, including PE pipes, plastic bottles, wood, waste copper wires, plastic films, woven bags, paper, circuit boards, thin metals, medical waste, used household appliances, and domestic waste. It is also used in vehicle recycling and for the treatment of domestic waste.   When it comes to applications, we carefully select the appropriate knives for the shredder equipment, depending on the type of waste being recycled. When it comes to knife types, knives can also be classified according to the type of shredder, as follows: single shaft shredder blades, double shaft shredder blades, three shaft shredder knives, and four shaft shredder knives. So, what are the main factors that affect the service life of the cutting knives in shredder equipment? 1. Structure of cutting knives: This includes the cutting gap, the tool angle, and the surface roughness of the knife cutting edge 2. Raw materials for cutting tools: workable material selection for different shredding. 3. Heat Treatment of cutting Tools: Hardness of the blade, uniformity of hardness on the same surface, suitable hardness for different shredding. 4. Tool rotation speed: That is, the shredding speed of the tool relative to the material; 5. Shredding Force of the cutting blade, which is the power of the shredder equipment.

• Operating a single or double shaft shredder precautions

  Jan 13, 2024

  What should we know when operating a shredding machine? 1. Regularly inspect all connecting bolts and the square head bolts for fixing the toothed plate. Prevents loosening and ensures the shredder's safety. 2. Lubricate each bearing bush, large and small gears, and special-shaped gears 1 to 2 times per shift to ensure sufficient lubricating oil inside the bearing bush and reduce over-decomposition wear on the bearing bush and gears. 3. Control the feeding particle size to ensure it does not exceed the specified size. Your ability to maintain continuous and uniform feeding is key to preventing material blockage and ensuring the efficient operation of the shredder. 4. Regularly check the temperature of the bearing. The temperature rise of the bearing bush should not exceed 25 to 30 degrees Celsius above room temperature. 5. Clean the bearing slide way of the moving roller frequently to remove dust and impurities to prevent materials from entering the moving roller and causing accidents due to its inability to move. 6. When there is a sudden power outage, first disconnect the power supply of the motor to prevent accidents caused by sudden power restoration. Then remove the unshredded materials from the shredder to prevent the safety pin from being cut off due to excessive load when the shredder starts. 7. Pay close attention to the working condition of the safety pin. If the safety pin is cut off, immediately disconnect the power supply to prevent the large pulley from rotating idly in the sleeve for an extended period. This idle rotation may cause excessive wear on its mating surface and even lead to shaft seizing and other accidents, resulting in significant damage to the equipment and downtime. 8. Operators must strictly follow the safety technical operation procedures and should not operate at will to prevent personal and equipment accidents.
