Dual Motion Shale Shaker For Efficient All-Condition Adaptation.
1. Working Principle and Trajectory Switching Logic of Dual Motion Shale Shaker
Dual Motion Shale Shaker are driven by two vibration motors (or exciters) in coordination. By adjusting the angle of the motor’s eccentric blocks and rotational phase difference, two motion trajectories are accurately synthesized to adapt to different material characteristics and working condition requirements:
- Linear Trajectory Mode: The two motors rotate synchronously in reverse directions. The excitation forces in the vertical direction are superimposed, while those in the horizontal direction cancel each other out, making the screen box vibrate linearly along the screen surface. Materials jump and push forward rapidly, featuring fast conveying speed and large processing capacity, suitable for rapid screening of coarse particles and large-displacement material handling.
- Elliptical Trajectory Mode: The two motors operate at certain angle, and the excitation forces synthesize an elliptical trajectory. Materials perform tossing and rolling motions on the screen surface, prolonging contact time with the screen mesh, achieving a high fine-particle screening rate, and strengthening the screen’s self-cleaning ability to effectively avoid screen clogging with high-viscosity materials.
During operation, the two trajectories can be switched with one click via control knob without shutdown and modification, matching real-time changes in drilling fluid viscosity, solid content, material particle size and other working conditions.
2. Core Advantages: Performance Breakthrough Compared to Traditional Vibrating Screens
- Greatly Improved Screening Efficiency:The dual-track composite motion forms a “jumping propulsion” of materials on the screen surface, avoiding accumulation and prolonging fine particle screening time. The screening efficiency for fine particles (≥20μm) can reach over 92%, and the single-unit processing capacity reaches 80-150m³/h, far exceeding that of traditional vibrating screens of the same specification (50-100m³/h).
- Significantly Extended Screen Life:The scattering effect of the elliptical trajectory reduces direct material wear on the screen mesh and lowers the probability of screen clogging. The service life of the screen mesh is increased by 30%-50% compared with traditional equipment, greatly reducing consumable costs.
- Adaptive Adaptation to All Working Conditions:Supports stepless frequency regulation from 500-1800r/min, which can be flexibly adjusted according to material characteristics: increase frequency to strengthen separation when handling high-sand content materials, reduce frequency and switch to elliptical trajectory to prevent screen adhesion when handling high-viscosity materials, adapting to water-based, oil-based drilling fluids and various mining and solid waste materials.
- Stable Structure and Reliable Operation:Adopts high-strength screen box and high-quality shock-absorbing spring design. Dual-motor self-synchronization technology ensures stable vibration, enabling 24-hour continuous operation, adapting to harsh working conditions such as offshore platforms, onshore drilling and mining.
3. Core Application Scenarios
- Oil Drilling Solid Control: As the primary equipment for drilling fluid solid control, it separates solid particles such as drill cuttings and barite from drilling fluids, adapting to all scenarios including onshore wells, offshore platforms and shale gas wells.
- Mining Material Classification: Used for particle size sorting of ores and sandstones, balancing fine particle screening precision and coarse material processing efficiency.
- Environmental Solid Waste Treatment: Treats industrial sludge and river silt to achieve efficient solid-liquid separation and reduce solid moisture content.
- Trenchless / Shield Engineering: Adapts to shield mud and horizontal directional drilling mud purification, ensuring smooth construction.
