Cast iron cyclones – cone spigots (monocone)
The MPE Cyclone Division has combined the cone and spigot of its cast iron cyclones to make a single unit, aptly known as a “monocone”. The primary aim of the monocone unit is to reduce the number of components of the cyclone and ultimately eliminate the joint between the cone and the spigot.
Plans remain in place to include this design change to other cast iron cyclones when the need arises.
Please note that MPE Cyclones still supplies cast iron spigots and cones separately. In some cases the monocone design is not always practical for clients due to the design of the underflow tanks which may not accommodate a single component. This situation needs to be considered before purchasing monocones.
Recent testwork in the diamond operations have shown that flow disturbances in the cyclone is reduced and cyclone performance is constantly maintained as a result of the monocone installation.
To distinguish the difference in part numbers, the monocone has a “CS” naming convention, as compared to the traditional cone that has a “C” naming convention. All cones remain at 20 degrees and the overall length of the cyclone remains unchanged.
As this is a new development, the MPE Cyclone Division has begun rolling out the monocone design to the other cast iron cyclones.
The following monocones are already available: 
- C61-CS-20/120
- C61-CS-20/127
- C51-CS-20/150
- CL42-CS-20/100
- CL47-CS-20/130
- CL47-CS-20/150
To further improve the handling properties of the monocones, the MPE Cyclone Division has developed an assembly location point which is only visible on the outside of the cone. The intended purpose of this location point is to allow assemblers to lift the cones during the assembly process, thus making assembly easier and safer.
The production moulds have since been upgraded to assist assemblers with the lifting of these cones.
Based on feedback on the modifications above, the assembly location point now includes two cut-outs. This improves the overall grip of the sling once it is fastened to the monocone. This new design will first be tested and rolled out once proven to be successful.
