How to select a vibrating screen exciter?

1. Core Selection Criteria: Match Requirements to Scenarios

1. Material Properties Define Excitation Force

   • Particle Size: Coarse materials (e.g., ores) require low-frequency, high amplitude (5-8mm); fine powders (e.g., chemicals) need high-frequency, low amplitude (2-4mm).

   • Density & Moisture: High-density or sticky materials demand 30%-50% higher excitation force (e.g., iron ore screening ≥40kN).

2. Throughput Dictates Power

   • Formula: Excitation Force (kN) = Screen Load (tons) × 1.5~2.5 safety factor.

   • Example: 10 tons/h throughput → 15-25kN exciter + 5.5kW motor.

2. Key Parameters: Frequency, Amplitude, Type

3. Durability Design: Cost Savings in Details

• Material: Carbon steel (standard use) vs. stainless steel (corrosive/high-temperature environments).

• Sealing: IP65 rating for dustproofing—mandatory in mining!

• Bearings: SKF/FAG brands (2x lifespan, +30% cost).

4. Compatibility: Secure Installation & Stability

1. Mounting Hole Alignment: Measure screen bolt holes—custom brackets needed if deviation >2mm.

2. Dynamic Balance Test: Avoid resonance; recalibrate if noise exceeds 85dB.

5. Smart Control: Energy Savings & Efficiency

• Variable Frequency Drive (VFD): Cuts energy costs by 20% for fluctuating materials (+USD 420 cost).

• Remote Monitoring: Add sensors to track bearing temperature/vibration anomalies in real time.

6. Cost Analysis: Buy Right, Save More （for reference)

7. Industry Secrets: Avoid These Traps!

• Low-Price Scams: Exciters

• Vague Compatibility: Reject suppliers who omit installation blueprints!

• Poor After-Sales: Brands with <1-year warranty have 40% failure rates.
