Volumetric dosing; crushing is the volumetric dosing of materials such as liquid, powder and paint. Bulk density of raw materials varies depending on many reasons. For this reason, volumetric dosing devices must be calibrated continuously. Inaccurate dosing volumetric or gravimetric? It can also be seen as an answer to your question. If a very precise operation is not required, volumetric inflation is also used.
Gravimetric dosing; It means dosing that continues weighing continuously. The reason why it is not affected by the change in bulk density in the raw material is; In order to eliminate color errors, the material weight is weighed and dosed continuously. Very precise dosing volumetric or gravimetric? It is an important clarification for the question. In production techniques that do not require extreme precision extruder lines It is preferred to mix materials into it.
Why Gravimetric Dosing is Preferred?
It has a functional structure. It can be easily adjusted thanks to the load-cell system. Weight and extruder lines It is sufficient to process the additive ratio within its capacity. In a short time inflation with color change.
Thanks to its modular structure, in line with different shapes and capacities plastic side equipment additive dosing for injection is done.
A gravimetric dosing machine working with a stepper motor has a fixed additive ratio. injection rate does not change.
Wastes are reduced, during production plastic side equipment into inflation Savings are achieved in the additive and paint sent with
Savings are possible with gravimetric dosers. of recycling materials plastic side equipment also used in the construction extruder lines Its homogeneous additive provides economical use.
Gravimetric devices used in dosing processes have the capacity to pay for themselves in a short time.
Why Doser Should Be Used?
Any additives or dyes plastic to the processing process injection Dosers designed for plastic It is the device that is connected to the material hopper of the machine by flange. This point is the independent dosing point. on this point volumetric or gravimetric? The question may come to mind. Selection can be made according to the additive material to be used and the sensitivity content of the raw material. Dosing units are not concerned with the content of the main material. It does not guarantee the mixture of single volumetric and gravimetric dosing devices.
Gravimetric multiple dosing, that is, the mixing device, which is called a blender for short, provides gravimetric dosing of many materials, including the main material. Different materials are mixed homogeneously at the desired sensitivity. At this point plastic processing machines are not affected by speed changes.
Advantage of Using Blender
If crushed raw materials are used, blender should definitely be preferred. Density cannot be prevented in the crushing raw material. For this reason, it must be constantly changed, especially during the paint application. Dosing devices cannot do this precisely, but gravimetric multiple dosing gives accurate results.
