Graviblend generation with integrated material conveying

The latest generation of Graviblend, the innovative feeding and blending system from Colortronic Systems now comes equipped with a fully integrated material conveying system (mechanically and in terms of the system control). This means that there are fewer interfaces, it is easier to use, material changes require less time, resulting in increased savings.

Thanks to its reduced height, the new system also takes up less room than its predecessor. Graviblend is particularly suitable for highly demanding continuous production processes, typical examples being the manufacture of textile and chemical fibres, the extrusion of foam sheet and multilayer special-purpose films and the compounding of masterbatches. The system can be used for the continuous conveying, gravimetric dosing and intensive feeding of all freely flowing granular plastics, e.g. Polypropylene (PP), Nylon (PA), Polyethylene (PE), Polystyrene (PS), Polyethylene terephthalate (PET) and Polylactic Acid (PLA). Its performance is particularly suited to applications requiring the highest degree of formulation accuracy and homogeneity of blend.

The new Graviblend generation features a fully modular design and with its integrated material loaders can convey raw materials from silos, octabins and other storage containers. For easy operation, all functions are combined on the uniform user interface of the C2 control system.

Newly incorporated sight glasses in the material hoppers permit visual control of the material flow at all times. The system is rated for continuous 24-hour operation. Like its predecessor, it operates according to the tried-and-tested principle of differential metering, that is to say, each individual component is metered by weight. The synchronous metering of all materials ensures absolute adherence to the formulation and an optimum blend of the components.

Prior to delivery, every Graviblend feeding and mixing system, including the material loaders and the C2 control, is completely assembled and tested. Thus the customer receives a tested, ready-to-use system that can be assembled and put into operation quickly and easily. Thanks to the modular design of the system, all attachment units can be readily fitted and removed. To sum up, the Graviblend now offers the user more functionality and flexibility in less space.
