Size; Apparatus size
In mixing and powder processing technology, size refers to the process volume of a processing machine. The useful volume is derived from the apparatus volume. This is the maximum permissible batch volume that the apparatus of this size can process/mix/vacuum dry/synthesise.
The size of the device is often indicated by a type designation. amixon®, for example, designates its mixers with a letter code and a number. The letter code indicates the device type, the number indicates the maximum permissible useful volume in the unit [litre]. The type designation is:
- AM for conical mixers
- AMK for conical mixers for continuous mixing processes
- AMT for conical mixers/dryers/ synthesis reactors
- COM for container mixers
- EM for single-shaft mixers with standard drums
- HM for twin-shaft mixers
- KS for KoneSlid® mixers
- GS for Gyraton® mixers
- VM for vertical single-shaft mixers
- VMT for vertical single-shaft mixing dryers/reactors
However, it is very important to refer to the maximum permissible useful volume when comparing the prices and performance of different manufacturers. This is the maximum batch volume that the machine can process/mix in a single batch.
This information is extremely important because many mixer manufacturers base the type designation of their machines on the gross volume. Depending on the mode of operation, the effective volume is 25% to 30% smaller than the gross volume.
