APPARATUS FOR MINE WORKINGS ROCK DUSTING

摘要

The apparatus for mine workings rock dusting has tank for inert dust with outlet branch pipe connecting it to the ejector, this is connected to pneumatic feeder of compressed air and to pump-in transport sleeve with sprinkler, and includes filtration partition, this is installed near the bottom of the tank under the supercharge nipple and the outlet branch pipe, the supercharge nipple placed in front of the outlet branch pipe coaxially to it in the upper cavity of the tank over the filtration partition, pressure controllers for compressed air supply to the tank. The lower cavity of the tank placed under the filtration partition is connected to reduced pneumatic feeder. The supercharge nipple is installed with possibility of axial shift for control of its working position from 5.0 to 0.01 inner diameters of the supercharge nipple and fixation in initial and end positions.
