Features and Applications of Dual Motion Shale Shakers

The Dual Motion Shale Shaker is a screening device that employs a composite vibration trajectory of linear and translational elliptical motion, combining the processing capacity of a linear screen with the fine screening results of an elliptical screen. Through the coordinated operation of two motors, it achieves multi-directional movement of materials on the screen surface, significantly improving the efficiency of solid particle separation, and is particularly suitable for removing fine particles from drilling fluids.

This combined motion allows the material to not only move rapidly along the screen surface but also to tumble violently in the vertical direction, effectively breaking down the adhesion and agglomeration between material particles and preventing screen clogging. Compared with traditional single-track Shale Shakers, its screening efficiency can be increased by 20%-30%, making it especially suitable for screening materials with high viscosity, high moisture content, or uneven particle size.

I. Working Principle

The Dual Motion Shale Shaker adopts a unique dual-track motion mode. By adjusting the motor phase angle and speed, the screen box can simultaneously have both linear and elliptical running trajectories.

Technical implementation:

Two or three vibratory motors are typically used as the excitation source.

The motor uses synchronous reverse rotation technology to generate a composite excitation force.

When different combinations of motors are working, the trajectory can be switched freely:

Linear trajectory: suitable for high-viscosity mud treatment

Elliptical trajectory: Improving solid-phase separation efficiency

Translational elliptical trajectory: combining the advantages of both

II. Features and Advantages

1. Large processing capacity and strong separation capability

   It possesses the advantages of both linear and elliptical trajectories, significantly improving the efficiency of solid-phase particle separation.

   It can use ultra-fine screens up to 325 mesh, without clogging the screen holes, and has a large processing capacity.

2. Adaptable

   The vibration trajectory and excitation force can be adjusted in real time according to the working conditions to adapt to different drilling fluid properties.

   The screen box angle can be adjusted synchronously on one side, supporting non-stop operation and improving on-site convenience.

   Adopting a modular design, it is compatible with both onshore and offshore drilling platforms.

3. Reliable and durable

   The screen box is made of high manganese alloy steel with integral heat treatment and a heavy-duty anti-corrosion coating, resulting in high fatigue strength.

   Designed for heavy loads, it can withstand high vibration intensity of 8.5G and adapt to harsh working conditions.

   The screen features a pre-stressed hook edge design, ensuring a secure fixation, easy replacement, and extended service life.

4. Intelligent design

   Equipped with vibration sensors and amplitude control systems to ensure stable equipment operation.

   Optional intelligent monitoring system, which monitors equipment status in real time and issues early warnings of anomalies.

III. Application scenarios

Primarily used in the oil and gas drilling industry as a primary processing device in drilling fluid solids control systems:

Conventional land drilling: Separating cuttings, purifying drilling fluid, and protecting downstream equipment.

Offshore platform drilling: Compact design, space-saving, adaptable to offshore environment

Horizontal Directional Drilling (HDD): Addressing Trenchless Mud Circulation Systems

Coalbed methane exploration: processing coalbed methane drilling mud

Tunnel boring machine (TBM) construction: mud purification improves construction efficiency and reduces environmental pollution.
