Comparison of imported flaccid screen and domestic flaccid screen

The relaxation screen mainly realizes the screening of materials through the movement of one by one. The main screen frame of the relaxation screen is a traditional circular vibrating screen. The flywheel pendulum block is used to provide an exciting force for the screen body to make the screen body produce a circular motion. The high-efficiency polyurethane screen is installed on the fixed beam (connected to the screen body) and the floating beam (connected to the floating balance beam). Due to the staggered movement of the screen body and the floating balance beam, the screen plate is tightened and relaxed, forming a relaxation movement. The shearing rubber spring and the guide leaf spring transfer the exciting force to the floating balance beam to make the floating balance beam move linearly.

Comparison of imported flaccid screen and domestic flaccid screen

The imported relaxation screen adopts an eccentric flywheel type single-axis inertial vibration exciter, and the design life of the exciter bearing is more than 20,000 hours. The excitation force of the exciter can be adjusted by adjusting the angle of the eccentric flywheel. The equipment specifications are up to 3m (width) × 12m (length).
The screening efficiency can reach more than 95%. Low noise, design vibration isolation above 97%. Features of high-efficiency clean-coal relaxation screen: The highly elastic polyurethane screen has excellent wear resistance, and the designed service life exceeds 4000 hours. The sieve plate is installed by pressing in and out, which is convenient for replacement and maintenance of the sieve plate. Screening equipment with the same screening area requires low motor power.
    The domestic flaccid screen is a kind of equipment used for screening difficult-to-screen materials such as fine, viscous and wet (such as the classification of high-moisture coal and coke with high viscosity) and other difficult-to-screen materials. Its design principle Double vibration is generated by a single drive, that is, through resonance, one driver provides two vibrations: the linear vibration generated by the fixed frame driven by the vibration exciter and the vibration generated by the floating screen frame, which move relative to each other. Especially when the processed material is easy to block the screen, the flaccid screen can achieve a very high screening efficiency with a relatively small screen area without the screen being blocked. It is widely used in coal, electric power, coal chemical industry, metallurgy, building materials and other industries.
