In mining crushing, aggregate processing, and building materials production, vibrating screens serve as the pivotal equipment linking crushing operations to finished products.
Their primary functions include:
In practical applications, over 30% of screening efficiency issues stem not from equipment quality but from inappropriate selection.
Therefore, during the crushing plant design phase, correctly selecting the type, specification, and configuration of vibrating screens is often more crucial than simply pursuing “larger models”.
Features:
Applications:
👉In most RUNH 200–500 TPH crushing production line configurations, the inclined vibrating screen is the most commonly employed solution, balancing throughput, stability and maintenance costs.
Characteristics:
Applications:
👉In certain high-standard aggregate projects, RUNH recommends the horizontal screen as the finished product screen to enhance screening accuracy.
Characteristics:
Suitable applications:
Vibrating screen selection must be based on the design capacity of the entire crushing line, not the theoretical capacity of a single crusher.
General guidelines:
👉RUNH incorporates a 10%–20% screening margin in its design solutions to ensure stable operation under high-load conditions.
The wider the screen face, the higher the processing capacity per unit time.
Screen width is typically recommended to be ≥ 2.5–3 times the maximum feed particle size.
Excessively narrow widths may cause material blockages, while excessive width increases costs and vibration loads.
| Number of sieve layers | Applicable scenarios |
| Single layer | Single-size grading or pre-screening |
| Double layer | Two types of finished materials |
| Triple layer | Simultaneous production of multiple aggregate specifications |
👉RUNH Standard Configuration:
3-layer vibrating screen = Produces three finished particle grades in a single pass, reducing equipment requirements.
The more concentrated the particle size distribution, the higher the screening efficiency
When containing a significant proportion of particles at the critical size (close to the screen aperture), longer screening time or a larger screening surface area is required
High-humidity, clayey materials readily clog apertures
Solutions include:
High-density, highly abrasive ores require:
👉In mining projects, RUNH typically customises screen body structures and excitation parameters according to material hardness, rather than employing standard configurations.

Impact of Different Excitation Methods:
✔ Screen Mesh Types
✔ Vibration Damping and Support Systems
An effective vibration-damping system can:
As a provider of plant engineering equipment and solutions, RUNH offers more than just vibrating screens; we adopt a holistic approach to the entire production line:
✅ Tailor screening solutions based on project capacity, material properties, and finished product specifications
✅ Ensure seamless integration with crushers, feeders, and belt conveyors
✅ Provide commissioning services, parameter adjustments, and on-site optimisation recommendations
✅ Support overseas project installation and commissioning
In multiple crushing projects across Southeast Asia, Central Asia, and the Middle East, RUNH’s vibrating screen solutions have significantly reduced material return rates for clients while enhancing overall production stability.
✔ Assess production capacity first, then determine specifications
✔ Choose the screen type based on material properties, not solely on price
✔ Consider screening efficiency from the perspective of the entire crushing line
Correct vibrating screen selection is a crucial step in establishing an efficient, stable, and low-maintenance crushing production line.
