GRAVICOLOR 310/610

The high and consistent dosing accuracy of the GRAVICOLOR 310 and 610 mean that you can reduce the percentage of additives being dosed without a loss in quality and so save on materials and costs.

Independent of recipes, materials, or the operational environment, IntelliBlend analyses all process data achieving the best possible operating point at any time through continuous self-optimisation.

Recipe integrity gives you an excellent and consistent product quality. Any fluctuations in the amount dosed are automatically corrected by immediately adjusting the batch weight.

The proportion of masterbatch dosed is automatically adjusted depending on the amount of regrind available. The weighing accuracy is not affected from vibrations caused by the processing machine, as these are filtered out by a special algorithm.

With proven motan quality, you not only ensure the highest dosing accuracy, but also save costs in your plant thanks to the long service life of the unit, the integrated conveying control and continuous self-optimisation through the IntelliBlend function. A price-performance ratio that is guaranteed to pay off!

The basic unit of the GRAVICOLOR 310 and 610 is designed to offer a high degree of flexibility in terms of the configuration and number of components. Up to eight material hoppers with five different dosing sizes can be used variably on the unit.

The stainless-steel material hoppers have continuously welded joints. This guarantees you contamination-free operation and easy clean down due to the high-quality surface finish.

The viewing window in the front door and the large viewing panes in the material hoppers ensure an excellent visual control of the ongoing process.

Quick material changeovers and cleaning are improved by the optimised modular design. The large front door, removable weigh bin and mixing chamber make it easy to change materials. The material hoppers can be removed with minimum effort but can also easily be emptied using the quick discharge pipe that is attached to each material hopper. The large viewing window is removable so enabling the material hopper and the hopper loader mounted above to be thoroughly cleaned.

The material hoppers have been designed to optimise material flow. In addition, all hoppers on the GRAVICOLOR 310 and 610 can be removed with little effort and are easy to clean.

All components are dosed using the unique motan cone dosing system. These batch dosing and mixing units therefore guarantee maximum dosing accuracy.

Cone dosing opens centrally and allows for symmetrical material flow. Any potential material bridges are destroyed through the vertical movement of the cone.

So, a clean material flow is always guaranteed, even for difficult flowing regrind materials such as flakes. The material hoppers can be equipped with five different cone sizes. Thanks to the variable selection of dosing modules, we can offer a customised solution for your process.

The weigh bin can quickly and easily be removed without the need for tools and can be cleaned away from the unit.

The mixing chamber with an offset material discharge prevents dead zones and provides a completely homogeneous mix.

It can be quickly, simply and easily removed for cleaning without the need for tools and cleaned away from the unit.

By integrating conveying into the GRAVInet control you save money as no separate conveying control is needed.

It can control up to nine material loaders with a blower station and stand-by blower; i.e. material handling for an eight component mixing station and a processing machine.

For the installation of complex systems, you can network multiple GRAVICOLOR units with each other or with other motan controls of the CONTROLnet family. This guarantees a high degree of flexibility. A central WEBpanel provides an overview of the entire production.

The ionisation option blows ionised air into the weigh bin and mixing chamber. This reduces electrostatic adhesion of the materials to the surfaces of the GRAVICOLOR. This helps maintain a homogeneous mixture. The amount of ionised air can be individually adjusted via a throttle valve.

The sensor cleaning option uses a blast of compressed air to clean the lens of the infrared sensor during each batch cycle. This prevents dust accumulation on the sensor.

With the built-in sensor on the regrind component, the “regrind management” can be activated on the control unit. The intelligent control ensures maximum use of regrind and therefore a constant recipe mix with a step-by-step approach to recipe proportions.

The level monitoring of the individual material hoppers can be installed individually. This option allows for an alarm message to be given when the material level in the hopper is low.

You can easily install a GRAVICOLOR 310 and 610 on to the throat of a processing machine. The GRAVInet GC-E control has a feature that compensates for vibration or oscillation.

Material segregation is prevented because of the short distance material travels from the GRAVICOLOR 310 and 610 mixing chamber to the machine throat.

Of course, the dosing and mixing station can also be placed next to the machine or operate as a central station feeding multiple processing machines.

The GRAVInet GC-E control system features an open network architecture based on Ethernet. The full colour touch-screen display is intuitive and easy to use, making it fast and safe to operate. It has comprehensive tools for sequence and process control. A regrind management function prevents overdosing of other components.

CONTROLreport offers you reporting and documentation functionality for quality assurance and it delivers advanced service functions and graphical display of process data.

Event reporting is used for downstream analysis of parameter changes via the control.
