This vibrating mining screen features a circular motion trajectory and is a new, high-efficiency, multi-deck screen (typically 1 to 4 decks). It sorts materials by particle size and suits a wide range of screening operations, including heavy-duty, medium-duty, and fine screening. It serves as ideal screening equipment for primary crushing, secondary crushing, and final product processing.

This mining vibrating screen was developed by Sandreck using advanced design concepts. The product reflects continuous refinement, incorporating years of practical experience in screening applications across sectors such as metal mining and aggregate processing. It is widely applicable to diverse screening operations in industries including aggregates, metallurgy, metal mining, and coal.

Mining Vibrating Screens Working Principle

The vibrating screen primarily consists of a screen box, screen mesh, vibrator, vibration-damping spring assembly, and a base frame.

An electric motor drives the vibrator’s eccentric blocks at high speed via V-belts. The rotating eccentric blocks generate significant centrifugal force, causing the screen box to move in a circular path with a specific amplitude. The screen box transmits impulses to material on the inclined screen surface, resulting in continuous throwing motion. As the material interacts with the screen surface, particles smaller than the mesh apertures pass through, thereby achieving the screening process.

Advantages of Vibrating Mining Screens

1) Rational Design, High Processing Capacity

The mining vibrating screen features a small amplitude, high-frequency design with a steep inclination angle, significantly improving processing capacity and screening efficiency.

2) Stable Vibration Source, Powerful Excitation Force

Vibrating mining screens use a cylindrical eccentric shaft exciter and adjustable eccentric blocks to control amplitude. It provides a stable vibration source and powerful excitation force while ensuring easy operation and maintenance.

3) Flexible Adjustment, Wide Applicability

Options include woven spring-steel mesh or perforated screen plates. Simple screen replacement allows the equipment to meet diverse production requirements.

4) Optimized Structure, Long Service Life

The screen employs rubber vibration-isolation springs, ensuring a long service life and low noise levels. High-strength bolted connections join the cross-beams and screen body, providing robust structural integrity. The side plates are constructed from boiler-grade steel for superior impact resistance. The vibrator uses large-clearance bearings with oil-bath lubrication to ensure quiet operation.
