EarthQuake Rotary Screening Buckets for Excavators

The Earthquake Rotary Screening Buckets are available for mini excavators from 1.5T to excavators up to 38 tonnes.

Rotary Screening Buckets (RSB's) offer several advantages for excavators, making them valuable tools for various applications:

• Increased Efficiency:

  • Faster Screening: Rotary screening buckets significantly outperform sieve buckets, achieving screening rates 5 to 10 times faster. This translates to increased productivity and reduced project timelines.
  • Screen Size Options: Screens can be removed and replaced with different size apertures (grids) to allow for sizing, resizing and different material types.
    
    

• Improved Material Handling:

  • Versatility: They can handle a wide range of materials, including soil, sand, gravel, and construction debris.
  • Reduced Waste: By effectively separating materials, they minimize waste and maximize the use of valuable resources.
    
    

• Cost Savings:

  • Reduced Labor: Rotary screening buckets often eliminate the need for additional equipment and personnel, leading to lower labour costs.
  • Lower Transportation Costs: On-site screening reduces the need to transport materials to separate processing facilities, saving on transportation expenses.
    
    

• Enhanced Operator Comfort:

  • Reduced Vibration: Compared to sieve buckets, rotary screening buckets generate less vibration, improving operator comfort and reducing equipment wear and tear.
    
    

• Environmental Benefits:

  • Reduced Landfill Waste: By promoting material recycling and reuse, rotary screening buckets contribute to a more sustainable approach to construction and waste management.

If you're considering using an excavator for material screening, rotary screening buckets can be a highly efficient and cost-effective solution.

How do rotary screening buckets work?

Rotary screening buckets for excavators work by utilising a rotating drum or basket with perforated openings to separate materials based on size. Here's a simplified breakdown:

1. Material Loading: The excavator fills the screening bucket with the material to be processed.

2. Rotation: The hydraulic system of the excavator powers the rotation of the drum or basket.

3. Screening: As the drum rotates, the material within is agitated and moved. Smaller particles pass through the perforations in the screen, while larger particles remain inside the bucket.

4. Separation: The screened material (smaller particles) falls through the perforations and is discharged. The larger particles are retained within the bucket and can be discharged separately.

Key Components:

• Rotating Drum/Basket: The core component, designed with perforated openings of varying sizes to control the screening process.
• Hydraulic Motor: Provides the power for the drum's rotation.
• Screen Mesh: The perforated surface that determines the size of particles that can pass through.

Benefits of this Mechanism:

• High Efficiency: Continuous rotation ensures rapid and efficient screening.
• Versatility: By changing the screen mesh, the bucket can handle a wide range of materials and particle sizes.
• Reduced Labor: Automates the screening process, minimizing the need for manual labor.

In essence, rotary screening buckets leverage the power of the excavator and a rotating drum to efficiently separate materials, making them valuable tools for various construction and material handling applications.
