This document discusses optimization of centrifuge dewatering processes. It begins by explaining why optimization is important to reduce costs from hauling and polymer usage. It then discusses various factors to consider like cake dryness, centrate quality, throughput, and polymer dose. The document presents case studies showing how optimization can save money. It proposes a systematic approach to optimization that involves testing parameters like polymer type and dose, centrifuge torque, and other variables. The outcomes of regular optimization are outlined as well as the importance of tracking performance over time to further optimize the system in response to changes.
