Double-Deck Shale Shaker

A Double-Deck Shale Shaker uses two screen decks arranged vertically in one shaker. The upper deck handles coarse drilled solids, while the lower deck provides secondary fine screening. Different mesh screens can be fitted to the two decks to match the required separation performance.

The dual-deck layout adds a second screening stage without requiring another shaker position. With 6.4 m² of effective filtration area and a rated capacity of up to 180 m³/h, the design is suited to drilling sites where mud flow rates are high but available solids control space is limited.

Features of Double-Deck Shale Shaker

1. Vertical Dual-Deck Design: Two screen decks are arranged vertically in one shaker, adding screening capacity without requiring a second shaker position.

2. Two-Stage Screening: The upper deck removes coarse solids while the lower deck handles finer solids with a different mesh.

3. High Capacity, Compact Footprint: 6.4 m² effective filtration area and capacity up to 180 m³/h in a compact shaker layout.

4. Translational Elliptical Motion: Carries cuttings toward the discharge end while allowing drilling fluid to pass through the screen.

5. Hydraulic Deck Angle Adjustment: 0° to +3° adjustment lets operators set the deck angle for different drilling conditions.

6. Modular Screen Panels: Different mesh sizes can be fitted for coarse or fine screening.

7. Integrated Wedge-Block Clamping: Secures the screen panels during continuous vibration and allows quick screen changes.

How the Double-Deck Shale Shaker Works

Drilling fluid feeds onto the upper screen deck and spreads across the screen surface. Translational elliptical motion moves drill cuttings toward the discharge end, while drilling fluid and undersize solids pass through the screen mesh.

The screened fluid then moves to the lower deck for secondary fine screening. A finer mesh can be fitted on the lower deck to remove additional solids. With larger cuttings removed on the upper deck, the lower screen receives a lower coarse-solids load and can focus on finer separation.

Treated drilling fluid exits the shaker and moves to the next stage of solids control.

Technical Specifications

Product Design Details

• Anti-Loosening Fasteners

  Thread locker applied to critical motor fasteners helps prevent loosening under sustained vibration.

• Full-Perimeter Splash Guard

  The full-perimeter splash guard keeps drilling fluid within the shaker and minimizes mud splashing during operation.

• Explosion-Proof Motor Configuration

  The shaker uses two 3.2 kW vibration motors for continuous operation. Ex d IIB T4-rated motors are available, with IECEx or ATEX-certified configurations supplied according to project requirements.
