Vibratory Screening – Practical Challenges and Production Losses

Other conference contribution, 2024

Vibratory screening is a crucial process in crushing plants, primarily aimed at separating different sizes of crushed materials. The production performance of the crushing circuit is often highly dependent on the vibratory screen performance. Despite understanding vibratory screening performance, multiple practical application at the industrial scale suffers production losses due to low-efficiency vibratory screen operation. The following paper provides an account of various practical issues encountered by vibratory screens at crushing plants for both aggregates and minerals processing plants. The practical issues originate from different sources such as physical plant construction, operational decisions by the plant, control strategies in process operation, and maintenance choices. Multiple data from different site surveys are used to demonstrate the lack of control of the screening process. The practical challenges list provides scope for future improvements in the screening process and careful consideration required by the companies providing screening solutions.
