square tumbler vibrating screen for Quartz sand

The square tumbler screen can also be called a gyratory vibrating screen. The vibration force generated by the motor drive device is an inertial force that changes in a certain direction around a fixed axis. The essence is the reciprocating inertia formed by the rotation of the eccentric wheel around the fixed axis. force. According to the structural characteristics and working principle of the R series square rocking screen, the screen surface is generally arranged horizontally or slightly inclined (the inclination angle is 0°~5°). The working principle of the R series square rocking screen is: after the tumbler screen is started, the equipment rocking body, that is, the screen box, reciprocates back and forth under the action of inertial force, and the screen box and the screen surface are connected periodically to shake, so as to make the screen surface The material moves in a directional jumping motion with the screen box. During the period, the material smaller than the sieve hole falls to the lower layer through the sieve hole and becomes the under-sieve material, and the material larger than the sieve hole diameter is discharged from the discharge port after continuous tumbling and jumping motion, thus completing the screening work. It can be seen from the working principle of the R series square rocking screen that the eccentric wheel distance of the transmission mechanism has an important influence on the movement trajectory of the material and the residence time of the material on the screen surface, that is, it has an opposite effect on the processing capacity of the screen and the screening efficiency influence. In actual screening operations, we can make trade-offs in terms of production capacity and screening efficiency according to specific circumstances.
