Working principle of double shaft shredder

The principle of the double-shaft shredder is the basic principle of using a beating tool. Driven by the high-speed and high-torque motor, the hammer on the main rotor hits the objects to be crushed into the cavity in turn, thereby tearing the objects to be crushed. Specifications cracked into pieces. According to the working conditions of the tool, the double shaft crusher can be divided into dry system, wet system and semi-wet system. The dry system mainly means that the pulverized material must pass through the cyclone sorting system to separate metal from non-metal, and the whole system is equipped with a dust removal device. The new twin-shaft shredder wet system means that water is sprayed during crushing and flushed during sorting. The semi-wet system sprays a small amount of water only when crushing is required to prevent dust, sample handling and clean-up without cleaning.

The main elements of choosing a double shaft shredder

1.Motor: The motor should use the national standard product produced by the original factory. When choosing a metal shredder, it must never be recharged with a refurbished motor or a non-national standard motor, because the copper enameled wire diameter of these motors cannot meet the rated current requirements of the rod machine. Therefore, the motor is easy to burn out or the driving force is insufficient, which affects the rotation speed of the metal shredder and the overall crushing effect.

2.Bearing: The quality of the bearing directly affects the production efficiency of the shredder and the quality of the particles. It is best to choose bearings produced by large regular manufacturers. In addition, bearings produced by small factories should not be used, but at the same time special attention should be paid to counterfeit products.

3.Steel plate: The thickness of the steel plate must meet certain requirements, and the service life of the standard steel plate is more guaranteed.

4.Blades: professional manufacturers have blades of various specifications, which are suitable for different materials, and some blades called general-purpose multi-functional shredders will have differences in output and blade wear according to different crushed materials. selection process
It is necessary to verify the blade specification, material and mouth shape.
