What Is a Square Linear Vibrating Screen?

The Square linear vibrating screen, also known as a linear screen, is a screening device widely used across various industries. It is a mechanical device that primarily utilizes a vibration motor as the source of vibration, causing the material on the screen mesh to be thrown upward while moving forward in a straight line. It features low energy consumption, high throughput, a simple structure, ease of maintenance, a fully enclosed design that prevents dust leakage, and automatic discharge. Due to its performance and characteristics, it is ideally suited for assembly line operations.

Working Principle of Square Linear Vibrating Screen

The square linear vibrating screen is a general-purpose vibrating screening device driven by two vibrating motors. When the two vibrating motors rotate synchronously in opposite directions, the excitation forces generated by their eccentric blocks cancel each other out in the direction parallel to the motor axes.

When the eccentric blocks rotate in the same direction, the resultant force perpendicular to the motor axes reaches its maximum value. Therefore, the motion trajectory of this series of vibrating screens is a straight line.

The two motor shafts are at a certain angle to the screen surface. Under the combined action of the excitation force and the material’s own gravity, the material is thrown up on the screen surface and jumps forward in a straight line, thereby achieving the purpose of screening and grading.

Features of Square Linear Vibrating Screen

High Screening Efficiency

Screen aperture sizes range from 3/8 inch (10 mm) to 400 mesh (38 microns), with screening efficiencies exceeding 96%.

Large Processing Capacity

Screening areas range from 500 mm to 1,500 mm wide and 1,500 to 4,000 mm long, allowing for a processing capacity of up to 20 tons per hour.

Multi-Stage Screening Capability

Single or multi-layer configurations are available, separating 2-7 different product specifications at a time.

Dust-Free Screening

Fully enclosed structure with automatic unloading of all incoming material, eliminating material buildup and making it ideal for assembly line operations.

Flexible Adjustment

Adjustable screen angle balances screening accuracy and output, with a maximum angle of 25°.

Easy Screen Replacement

Screen design allows for convenient and quick screen replacement (only 3 to 5 minutes). The design also allows for the use of various screen materials (stainless steel, nylon, special nylon, PP mesh).
