INTRODUCTION

The square swing screen transmits power through a belt drive to a crankshaft mechanism, generating a unique swinging motion. This motion is transferred to the screening surface, enabling rapid and uniform dispersion of materials at the front section of the screen, thereby achieving efficient screening. Traditional vibrating screens face a trade-off between screening precision and throughput: prioritizing precision sacrifices production capacity, while emphasizing high throughput compromises accuracy. The square precision swing screen is specifically engineered to resolve this conflict, offering both high precision and large-throughput efficiency. This advanced screening equipment is widely utilized in industries such as chemical processing, metallurgy, non-ferrous metals, non-metallic minerals, food processing, and abrasives manufacturing.

WORKING PRINCIPLE SIMULATION DIAGRAM

The FYB square swing screen, also known as a reciprocating screen, derives its motion from the inertial force generated by its drive mechanism. This inertial force, characterized by a regular directional change around a fixed axis, is fundamentally formed by the reciprocating inertial force of a rotating eccentric wheel. Based on the structural features and working principles of the swing screen, its screen surface is typically arranged horizontally or with a slight inclination (0°–5°). The working principle of the swing screen is as follows: After startup, the screen body (i.e., the screen box) performs a forward-and-backward reciprocating motion under the action of inertial force. The screen box drives the screen surface to undergo periodic rocking, causing the material on the screen surface to perform directional jumping motion in sync with the screen box. During this process, particles smaller than the screen aperture pass through the holes to the lower layer, forming the screened undersize material. Particles larger than the screen aperture are discharged through the outlet after continuous rolling and jumping, ultimately completing the screening process.

From the structure and working principle of the FYB square swing screen, it is evident that the eccentricity distance of the transmission mechanism critically influences the material’s motion trajectory on the screen surface and its retention time. This directly impacts the machine’s processing capacity and screening efficiency. Therefore, in practical screening operations, adjustments can be made to prioritize either production capacity or screening efficiency based on specific requirements and conditions.

MATERIAL MOTION TRAJECTORY

FYB square swing screens demonstrate higher processing capacity and screening efficiency compared to conventional inertial vibrating screens with same or similar configurations. This essential advantage stems from the equipment's ability to actively control material movement trajectories and retention time on the screening surface. Within the confined space, materials follow non-linear curves with continuously varying speed and acceleration, significantly increasing contact opportunities with screen apertures and consequently enhancing the screening rate.

The figure below visually demonstrates how FYB swing screens modify and regulate material trajectories and residence time on the screening surface to achieve improved separation efficiency.
