A method for grindability testing using the Scirocco disperser.
In the early stages of development of a new Active Pharmaceutical Ingredient (API), insufficient material quantity is available for addressing processing issues, and it is highly desirable to be able to assess processability issues using the smallest possible powder sample quantity. A good example is milling of new active pharmaceutical ingredients. For particle breakage that is sensitive to st...
متن کاملParametric dependence of particle breakage mechanisms
It has been observed that the pattern of particle impact breakage in two-dimensional systems is a result of two mechanisms. AMechanism IB accounts for the breakage induced by the stresses that appear in unbroken particles. AMechanism IIB breakage is due to the buckling of the Mechanism I fragments. The purpose of this paper is to try and understand the parameters that govern the magnitude of th...
متن کاملComputer simulation of impact-induced particle breakage
The breakage induced in single circular particles that impact on solid plates has been studied using a two-dimensional simulation of solid fracture. The simulation allows the computer 'experimenter' to vary independently material properties such as Young's modulus, Poisson's ratio and work of fracture, flexibility that is unavailable in direct experimentation. Where comparison is possible, the ...
متن کاملMicromechanical Considerations of Particle Breakage Using Discrete Element Method
Using DEM (Discrete Element Method), a model is presented to simulate the breakage of two-dimensional polygonshaped particles. In this model, shapes of the particles generated after breakage are predefined and each uniform (uncracked) particle is replaced with smaller inter-connected sub-particles. If the bond between these sub-particles breaks, breakage will happen. With the help of this model...
