Theoretical study of the model of air flow movement near the shaped shelter of the rough grinding machine

Introduction. The article deals with the problems of choosing equipment for effective dust removal and subsequent dust collection. The dependences describing the fields of flow velocities in the closed area of the abrasive wheel, influencing the formation of streamlines of flow motion near the shaped shelter of the rough grinding machine, are considered. Problem Statement. The objective of this research is to develop a mathematical and computer model of the aspiration of a rough grinding machine. Theoretical Part. To accomplish the set task, the modern software Аnsys was used as well as the previously obtained results of the dispersion analysis of abrasive-cast iron dust during grinding, which had been carried out using a High-class device — an Analysette22 NanoTec laser granulometer. Conclusion. The results of the analysis, the obtained fields and the values of the air flow velocities in the workplace of the machine operator will be compared with the hovering rates of various dust particles, which will allow us to determine the efficiency of the rough grinding machine shelter, including at the design stage.
