OSTI.GOV Technical Report: Optimization of Comminution ...

Abstract. The goal of this project was to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process were used to study methods for optimizing the product size distribution, so that the amount of excessively fine material produced could be minimized.

Effect of homogenization method on DNA yield and fragment size

The mortar and pestle, including the CryoGrinder, disrupt more by crushing and grinding, and as such generated relatively large fragments. This was very apparent with the CryoGrinder. Grinding and crushing apparently have less of a deleterious effect on DNA than shearing.

Crushing Vs Grinding - Minerallurgy

Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero electrical charges of the ...
