Single dose versus hopper grinding: hypothesis about the ...

Dec 26, 2009· There is no way the contrast between single layer/single dose, multiple layers in hopper grinding is . But the hypothesis implies there will be more multi-layer ground particles in the hopper grind. This means that the distribution of coarse grinds will be more dispersed for the hopper grind than in the single dose grind.
