Discrete Particle Simulation of Particle Flow in the ...

IsaMill is a high-speed stirred mill that has been newly developed in the mineral industry for fine and ultrafine grinding. In this paper, a numerical model that is based on the discrete element method (DEM) was developed to study particle flow in a simplified IsaMill. The DEM model was validated by comparing the simulated results of the flow pattern, mixing pattern, and power …

Three different agitator geometries for a dry stirred media mill with a horizontal drum were studied experimentally and by DEM (discrete element method) simulation. Two optimized models, model A with stirring arms oriented in the same direction and model B with inclined stirring arms, achieved more rapid grinding with the lower adhesion of particles to the mill than …
