Coal Sill screen Machine Automatic Vibration Separation Screen

February.28,2026

In coal mining and processing, vibrating screens are key equipment for coal grading, dewatering, desliming, and impurity removal. Different types of vibrating screens can be selected based on different process requirements, such as raw coal grading, coal powder screening, or dry screening of wet fine coal.

Linear Vibrating Screen

Using a dual-motor drive, the excitation force causes the material to move linearly across the screen surface.

Core Advantages: Simple structure, large processing capacity, high screening efficiency, and easy automation.

Widely used in dry and wet coal grading, dewatering, and desliming processes, especially suitable for high-volume applications.

Circular Vibrating Screen

The vibrator causes the screen box to vibrate in a circular or near-circular trajectory. The screen surface is usually installed at a downward inclination.

Core Advantages: Long screening path, which facilitates material stratification and high screening efficiency.

Commonly used for pre-screening and final screening in coal mines, especially suitable for processing raw coal with larger particle sizes.

Coal Powder Vibrating Screen

Typically a small vibrating screen designed for processes such as blast furnace pulverized coal injection.

Core Advantages: Excellent sealing performance, effectively removing sawdust, fibers, and other impurities from coal powder, ensuring smooth coal powder conveying.

Specifically designed for coal powder screening in blast furnace injection systems, ensuring the safety of subsequent processes.

Reciprocating Vibrating Screen

Driven by a vibrator, the screen plates perform alternating tension and relaxation reciprocating motion.

Core Advantages: Unique self-cleaning function for screen holes, effectively preventing clogging by damp, fine-particle materials.

Specifically designed for the dry screening challenges of 1-6mm damp fine-particle raw coal, offering high screening efficiency.
