Operation principle of the paddle mixer
Paddle blade mixers have some differences in design, which directly affect the features, parameters of the operation and the scope of use.
Briefly, all blade mixers can be divided into the following types:
By the way of operation:
- Continuous operation;
- Non-continuous operation (cycle type).
By the material of the housing/ body:
- Made of carbon steel;
- Made of high resistance steel HB400;
- Made of stainless steel AISI 304L or AISI 316L.
- Standard structure;
- With additional full loading/ charging device;
- With additional deagglomerators / milling devide with special cutting knifes.
In spite of the wide range of classification of the mixing machines a common and uniform principle of their operation is distinguished. Paddle mixers (or blade mixers or plough mixers) consist of a mixing chamber and a working shaft with paddles (or blades, or ploughs). There are also may have several shafts in the construction, depending on the volume of the mixed product and the scale of production.
Due to the rotation of these shafts, a centrifugal vortex motion is created, which is also called a «fluidized bed». This ensures mixing any product as intensively and as fast as possible in three planes. Due to these features the paddle blade mixers are demand in modern production facilities of many enterprises.
