Vibrating Screen

Advantage characteristics:

　　Vibrating screens in both seat and hanging styles;

　　The large pulley and the eccentric shaft have an eccentricity of 3-5 mm, which balances the overall movement of the large pulley when the vibrating screen vibrates, and increases the stability of the transmission;

　　The material on the sieve of the self-centering vibrating screen can achieve good looseness and delamination under the action of vibration;

　　The weight of the vibrating screen can be adjusted, and the amplitude of the sieve can be adjusted according to production requirements;

　　When the amount of minerals changes, the amplitude also changes. When the amount of ore is small, the amplitude increases and the vibration is intensified. When the amount of ore is large, the amplitude becomes small. Changes in the amount of ore will affect the "dynamic balance", causing some vibration in the center of the pulley;

　　working principle:

　　The principle of self-centering vibrating screen is to use the motor to drive the main bearing of the pulley. The centrifugal inertial force generated is added to the internal force of the vibrating system of the screen box, and the center of gravity of the screen box system is driven to make a circular motion. The mass of the eccentric weights on the heavy wheels should ensure that the centrifugal inertia generated by them can balance the centrifugal inertial force generated when the screen box rotates. The condition that the center of the pulley is not displaced in the space is that the centrifugal inertia generated by the rotation of the screen box is equal to the centrifugal inertia force generated by the eccentric weight, and the direction is opposite, and the power balance is reached at this time. Thereby, the "self-centering" of the pulley is realized, so that the center distance of the two pulleys of the size remains unchanged, and the looseness of the belt is eliminated.
