fine grinding minimising fines reduction

Process engineering: Particle size reduction techniques and ...

Feb 15, 2005 · The equation indicates that softer materials produce more fines [1]. Nearly all size-reduction techniques result in some degree of fines. So unless producing very fine particles is the objective, it usually is more efficient to perform size reduction in stages, with removal of the desired product after each operation. Hardware options

MODELLING FINES IN BLAST FRAGMENTATION AND ITS IMPACT ON ...

The Split system accounts for fines in two ways (Kemeny, 1994). Firstly it determines the minimum size of fragments (referred to as the fine-size) that can be delineated depending on resolution and scale of the image. Secondly it assumes that a percentage of the non-delineated area contains fines.
