3.1 Introduction. The reduction of bigger particles into smaller ones by the application of external (mechanical) force (s) is called comminution [ 1 ]. Pharmaceutical raw material may contain lumps that cannot be processed as such. For these materials, size reduction is an inevitable step.
Comminution (break-down) techniques. Comminution is the reduction of solid material particle size by fracture via grinding, milling, or similar processes. Comminution techniques are usually employed to produce particulate nanomaterials (e.g., powder) from larger-sized or bulk materials.
a particular comminution circuit, to find improvements in circuit design and operating conditions. This process has been carried out at a number of industrial sites that utilize a SABC circuit [1,14,15]. 1.3. Paper Objectives The primary aim of this work was to perform a diagnostic evaluation of the SABC comminution
