GN Diamond Drilling Solids Removal Unit

The GN Compact Diamond Drilling Solids Removal Unit (SRU) is specifically engineered for small mining rigs engaged in diamond drilling or core drilling operations.
  • The GN Compact Diamond Drilling Solids Removal Unit (SRU) is specifically engineered for small mining rigs engaged in diamond drilling or core drilling operations. This unit serves as an alternative to traditional drilling sumps and has gained recognition as a forward-thinking solution within the drilling industry. By employing a closed-loop drilling fluid system, the GN Solids Removal Unit offers a cost-effective approach to minimize environmental impact while significantly enhancing drilling efficiency.

    The GN Solids Removal Unit operates on the principle of direct circulation. The drilling fluid is directly pumped from the drill collar to the 2 panels GN Mini Shale Shaker GNZS752 for initial phase solids removal. Subsequently, a positive displacement feeding pump transports the drilling fluid from the shaker tank to the GN 9-inch bowl Mini Decanter Centrifuge for fine solids removal. The clarified drilling fluid is then returned to the drill hole for reuse. Additionally, this highly mobile unit incorporates a mixing chamber, mixing hopper, and pumps to facilitate precise and efficient addition of drilling fluid chemicals. The GNLW224 baby centrifuge, renowned as the world's smallest decanter centrifuge for drilling fluid treatment, enjoys popularity within the diamond core drilling industry.

    The GN Compact Diamond Drilling Solids Removal Unit (SRU) is meticulously engineered to cater to small capacity requirements while maintaining a minimal footprint. It excels in the separation of fine solids, offering superior performance for diamond drilling applications.

    The bowl of the GN Mini Centrifuge is constructed using SS304, employing centrifugal casting techniques to ensure exceptional durability. To safeguard the screw, Tungsten Carbide Tiles are employed for reliable protection. Additionally, the bowl solids discharge port is fortified with a tungsten casing, and a solids blocking ring is integrated to prevent the accumulation of solids.

    The liquid discharge weir height can be easily adjusted to accommodate various application needs, ensuring flexibility and adaptability. During transportation, the bowl assembly is supported by a secure bolts system, providing optimal protection for the bearings. These bearings are sourced from reputable brands such as NSK and FAG, guaranteeing their authenticity and reliability.

    In terms of electrical components, the SRU utilizes high-quality components from esteemed brands such as SIEMENS and Schneider. This selection ensures the unit's electrical systems perform at an optimal level, contributing to the overall efficiency and reliability of the SRU.
