Deep Dive into Efficiency CASE STUDY Copper Installation
· The SAG discharge screen experienced surges of material (25 -40 solids) from the SAG mill which overloaded their existing screen. During these frequent overload surges the stroke/throw reduced significantly. This caused a substantial reduction in screen efficiency.

· The existing SAG Mill Discharge screen had a single deck design of 3.6m x 8.5m and handled less than 1 900 TPH when screening at 13mm. This quickly became the process limitation. In an attempt to assist the movement of material off the deck and reduce the frequency of overloads the customer decided to incline the screen and upgrade the drive.
