CiDRA’s CYCLONEtrac Particle Size Tracking (PST) System is the only grind management system of its kind in the minerals processing industry. The CYCLONEtrac PST system was specifically developed to track the size of the particles present in hydrocyclone overflow streams. The system uses a sensor to report particle size in real-time to the control room. Operators can use this data to improve closed-circuit grind control strategies to achieve consistent target grind size. As a result of this novel technology, the CYCLONEtrac PST system allows mine sites to enhance hydrocyclone operation and grind efficiency as well as improve mineral recovery.
