Netherlands-based Dinnissen is now introducing a new line of Sustainable Pegasus® Mixers which make energy savings of up to 60% possible for mixing processes.
Â
In doing so, Dinnissen is responding to client demand for process technology which is sustainable and economical.
Â
This principle is the first step towards realising overall energy savings of 60%. In addition, a situation in which the raw material particles are floating gently through the mixer is ideally suited to spraying powders and liquids onto the particles. As a result, the raw materials which need to be added and mixed in are distributed over the floating particles as soon as they are fed into the mixer.
Â
The new series of Sustainable Pegasus® Mixers makes it possible to reduce mixing times to one third of the mixing times that can be realised using traditional ribbon mixers or single-shaft mixers. Reducing the mixing time further reduces energy consumption by 30%-40%. In addition, the short mixing time makes it possible to increase capacity by 15%-20%. Dinnissen recommends the standard application of a frequency control unit to allow for the stepless control of and input to the mixer. By controlling the speed of the mixer in this fashion, it becomes possible to further significantly increase the energy savings realised with the Pegasus® Mixer.
Â
The new series of Sustainable Pegasus Mixers® is also equipped with Dinnissen's special Energy Control Programme which controls the mixers as energy-efficiently as possible.
Â
This programme is one of the basic elements of the system and also results in significant energy savings in comparison to traditional ribbon or single-shaft mixers. The Energy Control Programme optimises the rotation speed of the mixers and ensures that the mixing process is carried out as quickly as possible while at the same time ensuring that the desired end result is achieved.
Â
The programme also has built-in functionality for determining the optimum filling capacity as well as the speed with which raw materials can be added to the mixer and with which mixtures can be discharged via extra large release valves on the bottom. The goal is simply to ensure that the entire process is carried out in as sustainable and energy-efficient a fashion as possible.
