| Beien machine | Mining | A pneumatic stowing machine that consists of a paddle wheel with six compartments working inside an adjustable airtight casing. This wheel is driven at a speed of 15 to 30 rpm by means of an air turbine through gearing. Two sizes of Beien machines are used having capacities of 30 yd 3 and 60 yd3 (22.9 m3 and 45.9 m3) of stowing material per hour, respectively. The dirt falls from the paddle wheel into the airstream in the pipe underneath the paddle box and passes along 6-in (15.2-cm) diameter pipes to the outlet, where a detachable deflector guides the stream of dirt into the required place in the packhole.
