The cutter head is the most important part of the shredder. The quality and wear of the cutter disc affects the efficiency of the shredder. Because the shredder mainly uses the blade to shear and shred the material, the requirements for the blade are very high. The price of a good shredder blade is also very high. If the blade of the shredder is replaced later, the cost will increase. Our blade can be used multiple times, and different cutterheads can be designed according to the customer's materials to increase the shredding. The service life of the machine reduces the purchase cost of the customer.
