Explain how an increase in feed rate would affect the efficiency of a screen and the reason for the said change
Answers
Answer:
The effectiveness is improved by reducing the capacity as then there will be more contacts per particle and better chances for passing through the screen aperture on each contact. ... Additional conditions would be no interference by other particles, as well as not sticking to, or wedging into, the screen surface
Explanation:
FACTORS THAT AFFECT SCREENING EFFICIENCY IN MINING
AGGREGATE SIZE AND COMPOSITION. The rough edge of a quartz shard tears at the screening material, but the tough engineering plastic resists its abrasive edges. ...
VOLUMETRIC FEED RATE. ...
SCREEN ORIENTATION. ...
VIBRATORY EFFICIENCY.
Explanation:
The amount of surface moisture present in the feed has a marked effect on screening efficiency, as does the presence of clays and other sticky materials.
