  • Wet Milling Process Custom Milling Consulting

    Wet milling also called wet media milling is a process in which particles are dispersed in a liquid by shearing by impact or crushing or by attrition. A mill is charged with media (small beads or spheres) and activated by a high-speed agitator shaft to separate the individual particles. When the agitator rotates it transmits kinetic energy

  • 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.

However the viscosity of the pulp (density) increases with the fines of the particles therefore fine milling requires a lower pulp density. As a result of this a pulp density of 30 solids by volume should be chosen for the tests.
