Lab, pilot and industrial refining increased the biomass digestibility for lignocellulosic biomass relative to the unrefined material. The sugar conversion was increased from 36% to 65% at 5 FPU/g of biomass with industrial refining at kWh/t, which was more energy efficient than lab and pilot scale refining. There is a maximum in the sugar ...

The Operating Principal. P ulverization takes place in the central chamber of the MicronMaster® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the highvelocity collisions between particles of the process material itself.

Selection functions and breakage patterns of the various size fractions in the feed may be needed. Scaling down the size of balls used in laboratory and pilot plant ball mills to simulate the ball action in large diameter ball mills would seem to be a step in the right direction. However, the mill feed would have to be scaled down ac cordingly.

However, as by definition no existing plant is available for calibration in greenfield scenarios, the use of simulation in ball mill circuit design has been limited. Running a pilot ball mill circuit can overcome this problem but this requires a reasonably large sample and therefore can be costly. In addition a valid scaleup procedure is required.
