<p>Mixer 5 receives plaster material from storage container 7 by way of hopper 8 and serves to mix it with water and makes it available via pump 9 at outlet 15. A motor 10, which is axially disposed relative to the mixer 5, drives the latter and the pump 9 by way of gearing 11. A compressor mounted under cowling 26 on top of the motor is also driven by the motor and supplies compressed air to outlet 40 and the latter and outlet 15 are, in use, connected to a spray nozzle (not shown). <IMAGE></p> |
