THE INFLUENCE OF SCREEN PARAMETERS ON PERFORMANCE CHARACTERISTICS

A series of laboratory screening tests have been performed with the objective of evaluating the effect of feed rate, screen length and screen motion on the quality of separation. The separation performance has been evaluated by the use of proposed ISO Standard measures which are based on the partition curve. The laboratory rig, the test programme and results derived from it are discussed. The effect of screen length, feed rate and screen motion on the levels of screen performance as indicated by these measures and a normalised separation size parameter are discussed in relation to the assumed screening conditions for the tests reported and conclusions are summarised.
