Particle breakage during compaction affects behavior and the quality of formed compact. This work conducted a numerical study based on discrete element method (DEM) to investigate effect particle dynamics compact properties, including size density distributions, pore properties. A force-based criterion Apollonian sphere packing algorithm were employed characterize behavior. The structures compa...

Early researchers hoped to describe ball milling as a series of particle breakage and re-breakage events. This review reveals that needed input population balance modeling (PBM), the “breakage function,” was never intended be taken literally but assumed solve matrix calculations. Along with liquid-tracer–based residence time, rates each size class (the “selection function”) could then back-calc...

propranolol (pl), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. the present study was concerned with assessing the cytogenetic effects of this drug on chinese hamster ovary (cho) cell line. mtt assay was then carried out to determine the cytotoxicity index (ic50) of the drug. the ic50 value of pl was 0.43±0.02 mm. to investigate the clastogenic effect...

Particle breakage is of fundamental importance for understanding the mechanical behaviour of sands and is relevant to many geotechnical engineering problems. In order to gain new insights into the mechanism of breakage of individual sand particles under single-particle compression, this study combines mechanical tests with three-dimensional X-ray micro-computed tomography (μCT) performed ‘in si...

This paper compares Discrete Element Model predictions for power and variations in impact and abrasion (low angle impact) breakage with power and grinding rate predictions from the more "traditional" JKMRC models. The DEM predictions are based on measured mill load sizings from a large industrial SAG mill at two operating conditions. The load sizings can also be predicted with reasonable accura...

• Modeling particle population from 3D texture image acquired using µCT. Incorporate random, preferential, and phase-boundary breakage in the model. Investigate non-random random events experimental comminution. The model explains around 84% of liberation data. Linking ore to process behavior though population. Prediction mineral is one key steps establishing a link between its processing behav...

The paper utilizes Petri_like_net structure in developing an intelligent expert control system to achieve optimum grinding by regulating the parameters of the grinding mill. The work establishes an appropriate theoretical background that helps to predict dynamic breakage characteristics of particle size distribution of materials, adequately supported by experimental data.
