A conical mixer has – as the name suggests – a cone-shaped mixing vessel in which two or more components are mixed.
In contrast, the design can also be drum, cylinder, cube or tetrahedron due to the geometry of the mixing vessel.
Cone mixers are usually batch mixers or discontinuous mixers, in which batches of mix are processed and removed one after the other (in contrast to continuous mixers).
According to the type of force input, a cone mixer may have a movable mixing hopper or movable mixing tools – usually these are augers or paddles / paddles. Accordingly, there are different types of cone mixers:
Cone screw mixer
The classic cone mixer has revolving spirals or an auger through which the material to be mixed is conveyed upwards along the container wall. The material sinks down over the center and is returned to the mixing process. This is known as the convective mixing effect.
Cone Paddle Mixer
The cone paddle mixer has a central paddle rotor. The rotation of the rotor causes a combination of vertical and axial movement in the cone mixer. The paddles carry the product to the surface where it disperses and sinks back down the center by gravity.
Cone twin screw mixer
In the twin-screw mixer, two symmetrically mounted screws convey the mix from the bottom to the top. Due to gravity, the mix flows downwards in the middle, where it is picked up again by the augers.
In contrast to the moving mixing tools, however, a conical mixer can also transfer force to the mixture inside by moving the mixing container. This type of mixer is often referred to as a drum mixer. A classic drum mixer is the cement mixer on the construction site.
MIXACO cone mixers have both moving tools and a moving mixing container that is turned upside down for the mixing process. Although it is not a classic drum mixer, the combination of moving mixing tools and overhead mixing produces better mixing results and is much easier to clean than in a conventional cone mixer with a fixed mixing chamber.
In addition, MIXACO conical mixers can be equipped not only with screws and paddles, but also with numerous other mixing tools, some of which are patented. Thus, a MIXACO conical mixer can be used more flexibly and individually than conventional conical mixers.
Especially in food production, smaller mixers with particularly short mixing cycles are in demand. Feeding, mixing process and discharge should be as fast as possible.
No other conventional conical mixer can be emptied as quickly as a MIXACO conical mixer, because the principle of exchangeable mixing vessels or containers means that the next batch can be mixed directly while the previous mix in the container is fed to the next production step. Process interruptions for emptying are virtually non-existent.
