View source for Beien machine

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  <sup>3</sup> and 60 yd<sup>3</sup> (22.9 m<sup>3</sup> and 45.9 m<sup>3</sup> ) 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 pack hole.  <i>Mason </i>
