Double-shaft shredder and single-shaft shredder are common types of shredders on the market. The equipment shreds materials through blades, reducing the volume of materials and facilitating subsequent processing. Many customers who have just come into contact with the solid waste shredding industry It is always unclear when choosing these shredders. The following two-shaft shredder manufacturers will introduce them in detail.

1. Shredding materials are different.

The materials that can be shredded by the dual-shaft shredder, such as various raw aluminum and cooked aluminum, waste tires, oil drum cans, color steel tile light and thin metal materials, electronic copper rotors, irregular large materials, etc. These materials are generally large in size and high in hardness, while the double-shaft shredder is driven by a reducer, with low speed and large torque, high crushing efficiency and stronger applicability.

The shredding materials of the single-shaft shredder are relatively limited, and are often used in paper mills, waste fabrics, leather scraps, domestic waste PE, PP plastic pipes, plastic films, woven bags, wires and cables, cans, metal filings, iron filings, etc. The material is shredded by the joint operation of the fixed knife and the moving knife, the torque of the equipment is limited, and the size of the feeding bin is limited. The single-shaft shredder has a smaller particle size than the double-shaft shredder.

2. The equipment structure is different.

The double-shaft shredder adopts "double motor + double hard tooth surface reducer" as the power drive, and uses the principle of mutual shearing and tearing of two relatively rotating knives and rollers to shred the material. The material enters the inside of the shredding box, and is shredded into small pieces by the comprehensive action of the shredding blade, such as tearing, squeezing, and shearing, and is discharged through the discharge hole under the equipment. The subsequent materials are sent out through the conveyor belt for further processing. Broken processing.

The single-shaft shredder adopts the drive design of "single motor + single reducer". The material enters the shredding box through the feeding system, and the box carries the shredding blade. The pushing box pushes the material to the vicinity of the blade, and the material passes through the shredder. The comprehensive action of the shredding blade tearing, squeezing, etc., shreds the material into small pieces, and discharges it from the screen hole to achieve the material shredding. The main structure of the single-shaft shredder is the blade spindle, fixed knife, carrying box, box bracket, feeding system, hydraulic pushing system, power system, electrical control system, etc. It is often used in various plastics, rubber, The fine crushing of waste such as woven bags and ton bags can process materials to a smaller particle size at one time.
