    Description

    INTEGRATING TECHNOLOGIES FOR MAXIMUM SEPARATION EFFICIENCY

    The BRANDT LCM-3D/CM-2 Cascade Shaker combines the scalping efficiency of a circular-motion CM-2 scalping shaker with the high throughput of a linear-motion LCM-3D primary shaker. Mounted above the LCM-3D primary shaker, the CM-2 shaker utilizes two (2) hookstrip screens, each with a flat, 0° deck angle. The circular vibration motion of the CM-2 is effective in maximizing scalping ability when large, sticky hydrated clays are encountered.

    The LCM-3D shaker, like the COBRA™ series, utilizes four (4) pretension screens, the 0°, +5°, +5°, +5° deck angle design and linear motion to remove solids from liquid. The linear motion of the LCM-3D is highly effective in rapidly separating and discharging solids, thus providing high throughput.

    To further increase separation efficiency, an optional VFD G-Force Controller is also available on the linear-motion LCM-3D shaker. This controller allows the operator to adjust the G-forces exerted on the shaker bed to one of three settings: 6.1 (NORM), 6.5 (HIGH) and 7.1 (MAX).

    VFD G-Force Controller

    OPTIMIZED SEPARATION EFFICIENCY THROUGH FLEXIBILITY, HIGH PERFORMANCE AND EASY OPERATION
    The Variable Frequency Drive (VFD) G-Force Controller affords customers the opportunity to manage shale shaker performance and screen life based on cuttings loading. By selecting one of the three settings (NORM, HIGH or MAX), operators are able to manage light to heavy cuttings loading on the shaker bed while reducing screen usage. The VFD utilized is simple, rugged and capable of being outfitted to new, or retrofitted to existing, KING COBRA™, KING COBRA Plus and LCM-3D shale shakers.

    Each of the three settings change the G-forces generated on the shaker bed. When drilling the top hole section with fast penetration rates (maximum screen loading), the MAX setting should be selected to efficiently remove solids from the drilling fluid (mud). In the intermediate hole section, the HIGH setting should be employed, while in the slow-drilling, bottom hole section, the NORM setting should be utilized.

    Settings may be adjusted while the shaker is in operation, thus giving the user the flexibility to adapt to changing drilling conditions without interrupting operations. This provides the operator more control over shaker performance and screen life. Varying the G-forces exerted on the shaker bed allows screen life to be extended by reducing the G’s as hole size and solids loading lessen.
