Single-shaft shredder versus double-shaft shredder

The shredder is an indispensable and important presence for the solid waste resource recycling industry. Because, the shredder can greatly improve the efficiency of the industry. If you need a shredder equipment, we first based on the material to be crushed after the function of selection, according to the characteristics of the material and the degree of ease of crushing to select the appropriate model. Many first contact shredder people, can not distinguish them, today to sort out the difference between the list shaft shredder and twin shaft shredder.

(1) The structure is different

Single-shaft shredder is mainly composed of a single spindle shredding blade group, fixed knife, box, feeding system, power system and other components. Through the rotation of a single shaft to drive the knife cutting materials will slowly shred the material, energy consumption is much higher than the dual-axis shredder, and the shredded finished product to be slightly smaller.

Two-shaft shredder mainly consists of two spindles consisting of shredding blade set, box. Feeding system, power system and other components. Through the mutual tearing, extrusion, shearing and other effects of the two knife rollers will be shredded into small pieces of material, and the body is slightly larger than the single-shaft shredder, shredding the finished material is relatively large, energy consumption than the single-shaft shredder to be small.

(2) knife type is different

Single-shaft shredder only assembled with a dynamic shaft, the blades are installed on this shaft, and the box on the fixed knife open to form a form of mutual shear.

Multi-shaft shredder dynamic axis into two, are set with blades, two axes of relative rotation, similar to the operation of the single-shaft shredder on the material.

(3) The working principle is different

Single-shaft shredder is the use of dynamic knife blade particles and fixed knife interaction, and through the screen to control the size of the material, the material will be shredded, shear, extrusion plus to a smaller size. Through the pushing system to send the material to the blade rotor for crushing, providing a large shear force to ensure a higher crushing output.

Double shaft shear shredder, is the use of two relatively rotating knives between each other shear, tear principle to crush the material. The use of dual motors and dual reducers, strong power, high operating stability.

(4) The difference in crushing materials

Single-shaft shredder is often used for more solid, smaller objects, can be processed to a smaller size of the material at one time. With a small size of the material, the screen can be replaced, the material is widely applicable, high efficiency and other characteristics. It is suitable for disposal of cans, trays, aluminum products, etc.

With high torque and high crushing efficiency, the twin-shaft shredder is suitable for a large number of hollow and light plastics. Such as PE film, PP pipe, rubber tires, auto parts and electronic waste.

In general the applicability of the twin-shaft shredder is stronger, and the scale of use of the twin-shaft shredder is more extensive, so the use of the twin-shaft shredder is more. In terms of shredding particle size, the single-shaft shredder shredding blocks to be smaller, single-shaft shredder it is more targeted, while the double-shaft shredder crushing blocks can be tailored according to the different materials, different shredding requirements. Single-shaft shredder and twin-shaft shredder is the strength of each, customers must think about understanding when purchasing, do not blindly lost the direction of choice.
