The dosing-mixing system GRAVIMIX FGB 25, is the largest system and developed for the efficient dispensing of free-flowing thermoplastic materials. The FGB 25 is applicable for large extruders, blow molding machines and a central mixer for multi-processing machines, where a consistently high quality of your end product is sought.
The registration of all used components makes an exact calculation in production. Because of the constant dosing accuracy, the additive percentage can be reduced to lower tolerance limits without rejects or a loss in quality.
The FGB 25 is suited for dosing of virgins (granulate), free flowing regrind, masterbatch and/or additives.This large Gravimix blending system can be installed directly on the processing machine, on a platform or next to the processing machine. Due to simple removable parts a quick cleaning and material change is guaranteed.
Components are dosed after each other into the weigh-bin, which is supported by an accurate weigh system. After weigh out, the complete batch is discharged into the mixing chamber and the horizontal mixer provides a consistent blend. A level sensor in the mixing chamber controls the total dosing cycle. The FGB 25 is an economic, reliable and user friendly blending system.
The system weighs with an accuracy of 0.01 grams. Weight of each component, depending on the type of operation, in 0.1 or 1 gram on the screen. (For user-interfaces see separate documentation).
Due to the modular construction of the FGB 25 series, there are 21 different designs available, from 2 to 10 components. The central hopper has a large opening with two slide valves and may be divided into two compartments. The remaining hoppers have slide valves and if necessary, there are two additional dosing cylinders optionally mounted.
Parts in contact with the material are made of stainless steel. Depending on the production, the FGB 25 comes with an economical, microprocessor based plug-in control or an advanced Industrial PC with touch screen operation. As an additional alert extra low-level sensors are provided (option). The controller also features a connection for a machine hopper sensor.
