High Efficiency Multi-Deck Probability Screening Equipment
The GLS probability screen is designed for high-efficiency material classification using probabilistic screening principles. It delivers large capacity, high screening accuracy, and low energy consumption, making it ideal for mining, aggregates, coal, and building materials industries.
- Capacity: 15–200 t/h
- Multi-deck design: 2–8 layers
- Screening efficiency: ≥95%
- Feed size: ≤50 mm
Engineered for fine material separation and high-throughput operations
Product Overview
The GLS series probability screen uses a multi-layer, large-inclination screen surface combined with high-frequency vibration to achieve efficient particle separation.
Unlike conventional vibrating screens, the probability screen applies a probability-based screening mechanism, where materials have multiple opportunities to pass through the mesh. This significantly improves screening efficiency, especially for fine and medium particle sizes.
It is widely used in:
- Mining and mineral processing
- Sand and aggregate production
- Coal preparation plants
- Chemical and building materials industries
Working Principle of Probability Screen
The probability screen operates based on probability screening theory, utilizing multiple screen decks arranged at steep angles.
Key Mechanism:
- Material is fed evenly onto the top screen layer
- High-frequency vibration disperses particles quickly
- Large inclination angle (30°–60°) accelerates material flow
- Multi-layer mesh increases screening opportunities
- Fine particles pass through early, coarse particles move downward
This design ensures:
- Faster material stratification
- Reduced material clogging
- Higher screening accuracy
