Dosingunit ZFP-Micro or TMA
The transitube® micro-dosers are designed for the dosing of small amounts of material with a high accuracy (e.g. master-batch). They can be mounted directly on top of the machinery hopper or with a special equipment which replaces the machine hopper completely. Besides the rotary valve model there is also a spiral version for fine powders available.
Field of application
To dose master-batch or other small amounts of materials, different dosing units are available. Especially in case of small outputs or high accuracy, microdoseres are necessary. By the need of an multicomponent-dosingunit it is also possible to combine different units to one complete system.
The microdoser type ZFP-Micro allows to dose even badflowing or bridging materials with a high accuracy. By using the antibridging technology of the bigger dosingunits ZFP, we are able to reach an accuracy up ti +/. 2 %. If a higher accuracy is requested the unit can also be combined with a gravimetric system.
The colouring unit type TMA is operated by an exchangeable rotary-valve where different sizes of indentations are available. By selecting the right metering roller a rough pre-selection of the output is specified. The fine tuning is done by adjusting the rotary speed. This way it is also possible to adjust the dosing volume according to the machine output. If the rotary valve is not useable (e.g. for powders) a spiral version is applicable.
