Product Introduction

This series of vibrating screens is designed by integrating advanced technologies introduced from abroad and considering the actual situation in China. The screen machine boasts advanced technical parameters, high processing capacity, and high screening efficiency. It uses a block eccentric vibrator for excitation and adopts specialized bearings for vibrating machinery, which have high load-bearing capacity and long service life. The screen machine adopts the self-synchronization principle, with the vibrator installed on the side plate, ensuring good stress conditions. The screen machine is connected using ring groove rivets, featuring a simple, compact, sturdy, and reliable structure, and is convenient for maintenance and repair. This series of vibrating screens uses rubber springs for vibration damping, ensuring stable operation and low noise during operation through the resonance zone.

Working principle

When the linear vibrating screen operates, the two motors rotate synchronously in opposite directions, causing the vibration exciter to generate a counter-excitation force. This force compels the screen body to drive the screen mesh to move longitudinally, allowing the material on it to be periodically thrown forward a certain distance due to the excitation force, thus completing the material screening operation. The linear vibrating screen is driven by dual vibration motors. When the two vibration motors rotate synchronously and in opposite directions, the excitation forces generated by their eccentric blocks cancel each other out in the direction parallel to the motor axis, while combining into a resultant force in the direction perpendicular to the motor axis. Therefore, the motion trajectory of the screen follows a straight line. The axes of the two motors are inclined relative to the screen surface. Under the combined force of the excitation force and the material's self-gravity, the material is thrown up and bounces forward in a straight line on the screen surface, thus achieving the purpose of screening and grading the material.
