High-solids enzymatic hydrolysis of ball-milled corn
High-solids enzymatic hydrolysis has attracted increasing attentions for the production of bioethanol from lignocellulosic biomass with its advantages of high product concentration water saving and low energy and capital costs. However the increase of solids content would worsen the rheological properties resulting in heat/mass transfer limitation and higher mixing energy.

Conical Ball Mill. Wet or dry (air swept) i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill specific power is multiplied by the feed rate to get the net mill power. This must then be increased by the anticipated mechanical inefficiencies
