The screen effectiveness of an industrial vibrating screen separates feed into overflow and underflow. Overall screen effectiveness ($E$) is defined as:
Options:
(A) The product of recovery of desired oversize material in overflow and recovery of undersize in underflow ($E_x \times E_y$)
(B) The ratio of total feed rate to screen area
(C) The difference between feed moisture and product moisture
(D) The ratio of deck angle to vibration frequency
Answer Key:
A
Step-by-Step Solution & Explanation
Overall screen effectiveness $E = E_x E_y$, where $E_x$ is the recovery of desired oversize in the overflow and $E_y$ is the recovery of undersize material in the underflow.
