    Description

    FUSING THE EFFECTIVENESS OF AN ELLIPTICAL MOTION SCALPING SHAKER WITH THE HIGH THROUGHPUT OF A LINEAR MOTION PRIMARY SHAKER

    The BRANDT LCM-3D/KING COBRA Cascade Shale Shaker combines two proven models in one package for the most effective liquid/solids separation machine on the market.

    The scalping shaker, which is mounted above the primary shaker, consists of a 4-panel KING COBRA that has been tuned to elliptical motion. Elliptical motion is effective in maximizing scalping ability when large, sticky, hydrated clays and other troublesome solids are encountered.

    The primary shaker consists of a 4-panel LCM-3D that has been tuned to linear motion. Linear motion, which allows for high throughput, is highly effective in rapidly separating and discharging solids.

    To further increase separation efficiency, an optional VFD G-Force Controller is available on the linear motion LCM-3D primary shaker, which 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). The LCM-3D/KING COBRA Cascade shaker also utilizes four repairable, pretension screens (primary and scalping) for cost savings.

    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.
