The friction between the stones heats the flour up gradually preventing the loss of the enzymes and the vitamins in the flour without compromising the baking quality. The grain is ground once and then sifted to remove large parts of leftover grain. These pieces can be milled once again to even out the size of the flour.

The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to 1.3 cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.

However, hammermills can be noisy, dusty, and generate heat during the grinding process [11]. Roller mills can produce 15-40% more pounds of ground grain for the same energy input compared to hammermills [7, 8,11]. This difference between mill types becomes less pronounced as the particle size gets finer and falls below 700 microns [7,8].
