Gas-dynamical Characteristics of Pneumatic Jet Comminutors with Central Material Feed

Results are given of the experimental study of gas-dynamical characteristics of pressure ejector devices for jet comminutors, in which the ejecting gas is supplied into the mixing chamber through a unit of nozzles located along the perimeter of the central channel destined for feeding the material to be comminuted. This data analysis has allowed to reveal advantages of this type pressure ejector devices in comparison with other constructive options and to state practical recommendations on their application in industrial facilities.
