flat-bottom mixing system

The two precision mixers shown on the left, namely the vertical mixer and the Gyraton® mixing silo, are examples of flat-bottom mixers. A flat-bottom mixing system is a mixer whose container bottom is largely flat in the product area. The bottom is flat or nearly flat. At most, it has a slight slope or curvature towards the discharge. As a rule, the mixing and discharge tools are mounted and driven from above, so that the mixing chamber remains free of a bottom bearing.

Such systems are also advantageous for pasty, plastic or poorly flowing products. With a flat bottom, the product can be moved and mixed close to the bottom surface without dead space. 

Flat-bottom mixing systems can also serve as buffers or paste bunkers. In this case, they have a modified mixing tool and a correspondingly small drive. Downstream processes can be fed via one or more outlets close to the bottom. The almost flat bottom geometry also facilitates residual emptying and cleaning.
