ABSTRACT:
A dental amalgam producing machine having a rotatable arm adapted to receive an amalgam mulling container at one end and having a counter weight at the other end, the arm being inclined with respect to the horizontal. A belt disposed about a non-rotating pulley is also looped about the container to hold the container on the arm against centrifugal force and to spin it on its own axis as the container is carried about the arm axis of rotation. Centrifugal force alone holds the cup on to the arm and no other mechanical locks or restraints are needed.
