Screening

1. Overview

Screening attachments for skid steer loaders enable on-site separation of soil, compost, gravel, sand, and demolition waste. They are designed to sift and sort material for reuse or disposal, helping reduce hauling costs and improve efficiency. These units are commonly used in construction, landscaping, agriculture, and material recycling.

2. Applications

• Topsoil preparation and rock removal
• Compost screening
• Gravel and aggregate sizing
• Site debris separation
• Waste stream reduction for recycling
• Sand or fill material refinement

3. Compatibility

3.1 Mounting System

Mount Type	Compatible Loaders
Universal Quick Attach	All standard full-size skid steer loaders

 Ensure the skid steer has sufficient lift capacity to handle fully loaded attachment.

---

3.2 Hydraulic Requirements (if powered)

Some screening attachments use hydraulic motors to vibrate or rotate the screen for better efficiency.

Parameter	Typical Range
Flow Rate	10 – 25 GPM
Operating Pressure	2,000 – 3,000 PSI
Coupler Type	½″ Flat Face ISO
Case Drain	Usually not required

Passive (gravity-based) screeners do not require hydraulic power.

4. Types of Screening Attachments

Type	Description
Bucket Screeners	Scoop and sift material in-place with a vibrating or rotating screen
Screener Boxes	Drop material into a shaker box mounted on the loader, screened by vibration
Rotary Drum Screeners	Use a rotating cylindrical drum to sort materials by size
Flip-Screen Systems	Use inverted rotating bucket screen for fast on-site material separation

5. Key Components

Component	Function
Screening Chamber	Houses the mesh or perforated panels for material separation
Hydraulic Motor	Powers vibration or rotation (if applicable)
Mount Frame / Plate	Connects the unit to the skid steer’s quick attach system
Debris Guard / Deflector	Prevents larger materials from damaging moving parts
Interchangeable Screens	Allows selection of different mesh sizes for various applications

---

6. Technical Specifications (Typical Range)

Attribute	Value Range
Bucket Width	60″ – 84″
Screening Area	7 – 14 square feet
Screen Size Options	¼” to 4″+ mesh or hole sizes
Operating Weight	800 – 2,000 lbs (empty)
Output Capacity	20 – 60 cubic yards/hour

 Screen size affects throughput and accuracy—smaller sizes yield finer sorting but lower capacity.

7. Operation Guidelines

7.1 Setup

1. Attach screening bucket securely to the skid steer’s quick-attach plate.
2. Connect hydraulic lines (if required).
3. Verify the screen type matches the desired material separation goal.
4. Test screen function briefly before engaging full load.

7.2 Screening Process

1. Scoop or load material into the screening chamber.
2. Engage hydraulic controls or tilt/rotate as needed.
3. Let fine material fall through the mesh or drum while retaining oversize material.
4. Repeat in passes or use shake cycles to improve efficiency.
5. Empty unwanted material and reload as needed.

8. Safety Practices

• Always wear PPE: gloves, boots, eye and hearing protection
• Never reach into the screening area while powered or engaged
• Use screens appropriate for the material hardness and size
• Operate on level ground to reduce tip-over risk
• Secure loose materials in high-wind areas
• Shut off hydraulic pressure before maintenance or cleaning

9. Maintenance Schedule

Task	Frequency
Inspect screens for damage	Daily
Check hydraulic hoses/fittings	Daily (if applicable)
Clean screen and frame	After each use
Grease pivot/motor points	Every 10 hours
Inspect mounting hardware	Weekly
Replace worn mesh panels	As needed

10. Selection Tips

 Choose screen type and size based on material (e.g., topsoil vs. gravel)
 Ensure loader lift capacity can handle filled attachment weight
 For high-output tasks, select hydraulic or powered screeners
 Use interchangeable screen panels for multiple material types
 Prioritize units with reinforced frames for tough or abrasive materials
