Abstract We have carried out numerical simulation of the flow in jet mill ejector. The features ejector are an annular unit for supplying additional gas form a confuser section at inlet to accelerating tube, as well outlet tube. In course study, we varied length and angle supply. established optimal parameters ejector, which it has been most uniform distribution velocity use scheme under study ...

The grinding process has become widely used to improve the fineness and performance of fly ash. However, most studies focus on particle size distribution ground ash, while morphology is also an important factor affect cement paste. This article aims at three different kinds ash from ball mill vertical mill, observed by scanning electron microscopy (SEM) calculate spherical destruction (the rati...

clarithromycin (cla), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. the aim of this investigation was to prepare cla nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (sls) and polyvinyl pyrrolidone (pvp) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. different weight rati...
