crushing operations: (1) lower reduction ratios reduce fines generation and (2) choke-feeding the crushers produces better shaped aggregate but more fines. Fines that do not meet minimum particle size requirements for use in concrete find little use and remain stockpiled (in Georgia, these fines account for
MINIMIZE YOUR FINES. The limitation of fines is a requirement in different industries. In the cement industry and in general, in the handling process, it is crucial for the efficiency of stacking and reclaiming units that come after the crushing system (less clogging, power absorption, wear and dust emissions).
A method for reducing fines generation during a crushing operation comprises matching the peripheral roll speed to the drop velocity into the crusher of the material to be crushed . The method is particularly suited to high volume crushing coal where existing techniques result in the generation of a significant level of coal fines (-4mm).
