Dosing & mixing
FAQ for Experts. Answers by Experts.
mo explains: “Dosing accuracy” can be defined in many ways, depending on the application.
Generally, the term “dosing accuracy” is used to describe how accurately a dosing unit achieves the target mass or volume. …
mo explains: Separately dosed materials need to be correctly mixed to ensure that plasticisation results in a homogenous output material.
The purpose of dosing and mixing is to combine multiple materials in the right ratio. …
mo explains: In the context of continuous gravimetric dosing, “loss-in-weight” systems work by weighing the entire dosing module – the dosing hopper and its contents, the dosing device and drive unit – and measuring the decrease in mass as the material is metered. …
mo explains: Gravimetric asynchronous dosing stations meter the components of a mixture into a weighing chamber one after another. As each ingredient is added, the system measures the aggregate mass of all ingredients – a method described as “gain-in-weight”. …
mo explains: The choice of dosing devices depends on which materials and method you are using, and what throughput you require.
To choose the right dosing device for your application, you need to consider three key points: …
mo explains: A volumetric system doses material according to the space it occupies i.e. its volume; a gravimetric system determines the amount of material to be dosed by weight. …
