What is a Linear Vibrating Screen?

เอ เครื่องสั่นแบบเส้นตรง is a high-efficiency screening and grading equipment designed for the precise separation of powders, granules, and small bulk materials.
It operates using dual vibration motors that drive the screen mesh to perform a linear (back-and-forth) motion, enabling accurate particle classification and impurity removal.

This machine is widely used in food processing, chemical, metallurgical, pharmaceutical, and building material industries for dry or wet screening operations.

Role of a Linear Vibrating Screen in the Production Line

In a typical production flow:

Crushing → Conveying → เครื่องสั่นแบบเส้นตรง → Mixing / Packaging

The linear vibrating screen functions as a grading and impurity-removal unit by:

• Separating materials by particle size;
• Removing oversize or undersize impurities;
• Ensuring uniformity for downstream processing.

Key Functions of a Linear Vibrating Screen

1. Precise Grading and Classification

Equipped with multi-layer screens, it can separate materials into 2–6 different grades simultaneously.

2. High Screening Efficiency

The strong and stable vibration force ensures rapid material movement and high throughput efficiency.

3. Adjustable Vibration Parameters

Amplitude, frequency, and inclination angle can be customized for different materials and production needs.

4. Low Noise and Low Energy Consumption

Operates smoothly with a noise level below 75 dB, ensuring an energy-saving and worker-friendly environment.

5. Easy Maintenance and Cleaning

Quick-clamp screen design allows for fast screen replacement and simple cleaning during product changeovers.
