During the last decade numerous protocols have been published using the method ofballmilling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis (e.g. microwave, ultrasound, ionic liquids) chemistry inball millsis rather underrepresented in the knowledge of organic chemists.

Sep 20, 2018· A Discrete Elements Method (DEM) study of load movement within a SAGmill12,192 × 7620 (40′ × 25′) in normal operating conditions is performed. The purpose is to determine how the geometry of the lifters affects the kinetics of the load inside themill. Specifically, the changes produced by the incorporation of inclined lifters and spiral or helicoidal pulp lifters to the kinetics are ...
