Crusher Operation Relation between Feed size and Shape The greater reduction ratio the worse particle shape. Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. Breaking round particles gives flaky material. F l a k i n e s s i n d e x [%]
There are several considerations in designing an efficient crushing and screening plant. The first is the raw materials to be crushed. The quarry shot material should be analysed for maximum feed size, gradation, chemical composition, amount of clay, hardness and variations within the deposit or ledges.
