Twin Rotor, Contrarotating, Non Intermeshing Continuous Mixers

3 Twin Rotor, Contrarotating, Non Intermeshing Continuous Mixers [Pg.31]

Operating to give dimensionally accmate extrudate, the MVX had limitations. At relatively low throughput rates the dimensions could be held accurately, but as soon as output was increased dimensional accuracy became inadequate for section extrusion. This was probably caused by the system of feed control which uses an oscillating ram in the feed hopper. [Pg.31]

When used only as a compoimding unit to provide strip for later cold feed extrusion or injection moulding, the throughput of the MVX became more acceptable. [Pg.31]

Probably the major limitation on this machine was that it was only arranged with a single feed port. It was not suitable for adding curatives later in the mixing process. It was also difficult to control, until software programmes were developed to assist in mixer operation, but a fully automatic plant including materials preparation and compound stacking was operational fifteen years ago. The only manual intervention required between intake of raw materials and take-away of pallets of finished compound was to transfer extruded strip onto a takeoff conveyor. [Pg.32]

It appears that further development of the MVX concept may be under consideration. (46). [Pg.32]
