If you get an overview of the technology of solids mixing, you quickly get the impression that actually all industrially usable mixing principles have long been invented. Differences are at most visible in nuances of different manufacturers.
In principle, this statement is true, but there are exceptions! Continuous further developments of amixon® are approaching the goal of being able to empty a powder mixer completely!
There are continuous further developments on the part of amixon® for powder mixers with vertical mixing tools. They pursue the goal of user benefits of the operators:
amixon® powder mixers and dryers are tailor-made solutions manufactured according to the customer’s requirements.
The performance of vertical helical mixers is certainly undisputed. A helical mixing unit rotates around a vertically mounted axis. The mixing goods are conveyed upwards in the periphery of the mixing chamber. From the top, the goods flow downward, obeying the force of gravity. The downward flow takes place in the center of the mixing chamber.
The mixing tools of the amixon® mixers generally rotate slowly. Their peripheral speed is usually only 0.8 m/s to 2.5 m/s. This is the reason why amixon® precision mixers homogenize particularly gentle. They normally do not change the granulometry and texture of the bulk solids. Another major advantage is that the mixing tools are only supported and driven from above. In this respect, they meet the highest hygiene requirements and are virtually maintenance-free.
In some cases, however, users of standard vertical mixers have had to accept a disadvantage: If the mixing goods flow poorly (include particularly fine particles or are moist or greasy), then residues can stick to the spiral tool after discharging. In this case, complete discharge is not possible. Not even by particularly accelerating the rotation of the mixing tool.
This is exactly, where an innovative solution from amixon GmbH comes in. In the new generation of amixon® mixing units, the spiral tool is tilted either inwards or outwards. Tests have shown, that mixing efficiency is actually improved in this way.
In addition, this design detail increases the discharge efficiency quite considerably. Take, for example, a 2 m³ cylindrical amixon® mixer that has been mixing a milk-based baby formula. After discharging, the residual quantity is only 240 grams. This corresponds to a residual discharge rate of 99.983%.
The product residue on the floor can be effectively discharged by ComDisc® tools. The remaining mixing good is only a few grams of powder. Operators of this new generation of amixon® mixers enjoy three advantages:
