⊕ Introduction

Mining squareswinging screenThe processing capacity is large and the screening accuracy is high. Pursuing screening accuracy alone will sacrifice output, while pursuing high output will lead to a decrease in accuracy. Square precision swing screen is a screening equipment specially designed for the above problems with high precision and high output. It is widely used in industries such as chemical, metallurgical, non-ferrous metals, non-ferrous metals, food, abrasives, etc.

By using a mining square swing screen to vibrate and swing the vibrator, it is transmitted to the screen surface, allowing the material to quickly disperse at the front of the screen, thus achieving the purpose of screening.

Working principle of mining swing screen

From the perspective of the motion trajectory of the shaking body or screen box of the screening machine, the mining square swing screen, also known as the reciprocating screen, generates an inertial force in a regular direction around a fixed axis due to the vibration force generated by its driving device. Its essence is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the swing screen, its screen surface is generally arranged horizontally or slightly inclined (with an inclination angle of 0 °~5 °). The working principle of the swing screen is as follows: after the screen machine is started, the shaking body of the screen machine, that is, the screen box, moves back and forth under the action of inertia force. The screen box drives the screen surface to shake periodically, so that the material on the screen surface moves in a directional jumping motion together with the screen box. During this process, the material smaller than the screen surface aperture falls to the lower layer through the screen aperture, becoming the undersized material. The material larger than the screen surface aperture is discharged from the discharge port after continuous rolling jumping motion, and finally completes the screening work.

From the structure and working principle of the FYBS square swing screen, it can be seen that the eccentric wheel track of its transmission mechanism has a crucial impact on the material movement trajectory and the retention time of the material on the screen surface, which has the opposite effect on the processing capacity and screening efficiency of the screen machine. Therefore, in practical screening operations, we can make trade-offs between production capacity and screening efficiency according to specific situations and needs.

The movement of materials on the mining swing screen surface

FYBS type swing screen with the same or similar configuration has a higher inertia than general inertiavibrating screenWith higher processing capacity and screening efficiency, the essence of this model is that it can artificially control the movement trajectory and retention time of materials on the screen surface. In a finite space, due to the non-linear curves of velocity and acceleration of material movement trajectory, there is more contact between the material and the screen surface in the machine filter, which naturally increases the screening rate.
