18 mesh-120 mesh vibrating screen for silica sand classification
The square swing stack screen is also called reciprocating screen. The vibration force generated by its driving device is an inertial force that changes in a certain direction around a fixed axis. Its essence is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis.
The working principle of the swing screen is: after the screen machine is started, the screen machine shaker, that is, the screen box, reciprocates back and forth under the action of inertial force, and the screen box drives the screen surface to periodically shake, so that the materials on the screen surface follow the screen box. During the directional jumping motion, the material smaller than the sieve surface diameter will fall to the lower layer through the sieve hole and become the under-sieve material.
Silica sand rocking screen has higher processing capacity and screening efficiency than general inertial vibrating screen. Its essence is that this model can artificially control the movement trajectory and residence time of materials on the screen surface, that is, in a limited space, due to the movement of materials The trajectory is a nonlinear curve of velocity and acceleration. Therefore, the material and the screen surface have more contact with the machine filter, which of course increases the screen penetration rate.
Aiming at the above production problems of customers, the square rocking screen is redesigned so that it has a large processing capacity and at the same time ensures the screening accuracy. The single processing capacity is the same as that of the traditional linear vibrating screen under the condition that the screening accuracy value remains unchanged. -8 times; effectively solve the problems of site restrictions, excessive energy consumption, and increased labor costs.
