Vibrating Screen Design Calculation

1. Screening Efficiency

Screening efficiency is one of the most important indicators to evaluate vibrating screen performance. It represents the percentage of undersized particles (smaller than the screen aperture)
that successfully pass through the screen during operation. A higher screening efficiency means a more effective separation and less material loss.

Factors Affecting Screening Efficiency:

Material properties: Particle size distribution,moisture content, stickiness, and bulk density.

Screen surface: Aperture size, shape, open area, and inclination.

Vibration parameters: Amplitude, frequency, and vibration angle.

Feeding method: A uniform and stable feed ensures steady material flow and higher screening accuracy.

Calculation Method:

Screening efficiency can be calculated by sampling the oversize and undersize materials:

Efficiency =Mass of undersize in feed/Mass of undersize in product*100%

2.Throughput Capacity

Throughput capacity (or processing capacity) refers to the amount of material that a vibrating screen can handle per unit time, typically measured in tons per hour (t/h) or cubic meters per hour
(m³/h). This is a key parameter for evaluating production performance.

Factors Influencing Throughput:

Screen area: Larger screening surfaces increase capacity.

Methods to Improve Vibrating Screen Efficiency

1. Optimize Feed Material Distribution:

Even Spreading: Ensure the material is fed uniformly across the entire width of the screen. Uneven distribution leads to localized overloading and inefficient screening of other areas.

Controlled Feed Rate: Maintain a consistent and appropriate feed rate. Too much material can blind the screen and reduce stratification, while too little can waste screen capacity.

Feed Box Design: Utilize well-designed feed boxes and chutes that help spread the material evenly and absorb some of the impact energy, protecting the screen media.

2. Select the Right Screen Media:

Material Type: Choose screen media (wire mesh, polyurethane, rubber, punch plate) that is suitable for the specific material being screened.

Considerations include abrasiveness, stickiness, and particle shape.

Opening Size and Shape: Ensure the opening size and shape are appropriate for the desired separation and material characteristics. Tapered or slotted openings can sometimes improve screening efficiency for certain materials.

Open Area: Maximize the open area of the screen media without compromising strength or wear life. A larger open area allows more material to pass through.

Self-Cleaning Media: For sticky or damp materials, consider self-cleaning screen media, such as harp screens or anti-blinding solutions, to prevent pegging and blinding.

3. Adjust Screen Parameters:

Stroke and Frequency: Optimize the screen’s stroke (amplitude) and frequency (vibrations per minute) based on the material’s characteristics and desired separation. Higher frequency and smaller stroke are often better for finer separations, while larger stroke and lower frequency are suitable for coarser materials.

Deck Angle: Adjust the screen deck angle. A steeper angle can increase material travel speed and throughput but may reduce screening efficiency. A shallower angle can improve efficiency but may decrease throughput.

Direction of Throw: The direction of throw, determined by the vibrator’s counterweights, affects how material moves across the screen.

Proper adjustment ensures optimal material stratification and passage.

4. Maintain Screen Condition:

Regular Inspection: Conduct routine inspections of the screen media, support frames, springs, and vibrator mechanism.

Screen Media Replacement: Replace worn or damaged screen media promptly. Worn media can lead to poor separation and increased carryover of undersized material.

Springs and Dampeners: Ensure springs and dampeners are in good condition. Worn springs can alter the creen’s vibration characteristics.

Vibrator Maintenance: Lubricate and inspect vibrator bearings regularly. A malfunctioning vibrator can lead to uneven vibration and reduced efficiency.

Tensioning: Properly tension screen media (if applicable) to prevent sagging and premature wear, which can create dead spots.

5. Consider Material Characteristics:

Moisture Content: High moisture content can cause material to stick together and blind the screen. Consider pre-drying or washing if feasible.

Particle Shape: Irregular or elongated particles can be more difficult to screen.

Specific Gravity: The density of the material influences how it stratifies on the screen.

6. Utilize Advanced Technologies:

Multi-Deck Screens: Employ multi-deck screens for multiple separation stages or to increase capacity in a smaller footprint.

Grizzly Feeders: Use grizzly feeders before the vibrating screen to remove oversized material, protecting the screen and improving its efficiency.

Sensor-Based Monitoring: Implement sensors to monitor screen performance, feed rate, and vibration characteristics, allowing for real-time adjustments.

7. Proper Sizing and Setup:

Capacity Matching: Ensure the vibrating screen is correctly sized for the required throughput. An undersized screen will be overloaded, while an oversized screen might be inefficiently utilized.

Support Structure: A stable and rigid support structure is crucial to allow the screen to vibrate effectively without losing energy to its surroundings.

To improve vibrating screen efficiency, focus on proper screen selection, optimized vibration parameters, uniform feeding, regular maintenance, and smart monitoring. These measures improve throughput, extend screen life, and ensure stable product quality.
