Concept Metaphysics. The nature of cause and effect is a concern of the subject known as metaphysics.. Ontology. A general metaphysical question about cause and effect is what kind of entity can be a cause, and what kind of entity can be an effect.. One viewpoint on this question is that cause and effect are of one and the same kind of entity, with causality an asymmetric relation between them.

A method for simulating the motion of balls in tumbling ball mill under wet condition is investigated. The simulation method is based on the three-dimensional discrete element method (DEM) and takes into account the effects of the presence of suspension, i.e., drag force and buoyancy.

The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the results.

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.

The correlation between slurry holdup volume with ball loading, slurry solids concentration and feed flow rate yielded plausible results. ANOVA statistical tests (F-test and t-test) were utilized to assess the adequacy of the correlation equation
