GRAVIMIX FLECS

GRAVIMIX FLECS — 350 kg/h, 6 Components

A series designed for multi-component recipes: dosing of up to 6 components, regrind support and a capacity of 350 kg/h.

What six components means

A complex recipe looks like this: the main material, regrind, two different masterbatches, a filler and an additive. A six-component system controls all of these in a single unit, by weight and separately.

Trying to do this with two separate units of fewer components creates both a layout and a synchronization problem: when the dosing timing between the two units does not match, the mixing ratio shifts.

What changes as the number of components grows

Every additional component means its own chamber, dosing valve and calibration. As the system becomes more complex, two things become critical:

• Load cell resolution — if a low-ratio additive is measured on the same scale as a high-ratio component, accuracy becomes important
• Control software — the dosing order and timing directly affect the homogeneity of the mixture

Regrind management

FLECS manages regrind as a separate component and holds its ratio steady. In multi-component recipes, having regrind enter the equation as well is a situation volumetric systems cannot cope with in practice.

Do not buy more components than you need

If your recipe consists of two or three components, the capacity of the FLECS goes unused and raises the investment unnecessarily. The number of components should be selected according to your requirement and not inflated on the grounds that "it may be needed later" — unused chambers also bring a cleaning and maintenance load.

GRAVIMIX technology

The shared features of the series — ±0.01% weighing accuracy, the EasyClean tool-free dismantling design, touch control and consumption reporting — and why gravimetric dosing saves money compared with volumetric systems are explained in detail on the color and masterbatch dosing page. For the opportunity to test GRAVIMIX free of charge on your own line before buying, you can contact us.

For simpler recipes you can look at the MECS series, and for a higher capacity at the FGB5 series.

Installation and commissioning

On multi-component systems, calibration requires more steps than on single-component units: every chamber is weighed separately and the dosing time-quantity relationship is determined component by component. When the material changes — especially if the granulate size or the bulk density is different — the calibration of that component has to be renewed.

During commissioning, entering the recipes into the system and operator training also have to be planned; the benefit expected from a multi-component unit depends on the recipes being set up correctly. Defining recipes with the standard and the percentage method is set out with worked examples in the recipe definition section of the guide; it can be used directly in operator training.
