The influence of several process parameters like milling time ball‐to‐beaker volume ratio diameter of milling balls and rotation frequency on the Knoevenagel condensation of vanillin and barbituric acid in planetary ball mills was investigated. These parameters determine the

Properties of arsenic sulphide (β-As4S4) modified by ...

Arsenic sulphide β-As4S4 has been modified by mechanical activation in a planetary ball mill. As a consequence the solid-state properties and dissolution yield have been influenced. The following changes were observed: the increase of specific surface area changes in the morphology (the formation of submicron particles) the occurrence of nanoparticles (21–31 nm) changes in crystal ...

Energy-Efficient Technologies in Cement Grinding IntechOpen

2015-10-23  The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill. Four circuit configurations of HPGR can be used in grinding of materials clinker and slag such as : Pre-grinding unit upstream of a ball mill. Hybrid grinding. Semifinish grinding
