            Smart, Efficient dosing and mixing technology

            Ensuring the highest quality for your plastics

            Accurate dosing and mixing of components are vital to the production of high-quality material mixtures. The latest smart systems are essential for reproducibly producing a uniform material mixture which complies with its formulation.

            ProTec delivers this technology with the SOMOS® Gramix, SOMOS® Volmix, SOMOS® Batchmix and SOMOS® MiniMix dosing and mixing units. Depending on the task in hand, the machines operate continuously or batchwise, gravimetrically or volumetrically and can handle throughputs of 150 g/h to 2,500 kg/h. They are of modular design and expanding the dosing systems to handle up to nine components or changing over to another dosing process is straightforward.

            The dosing and mixing systems can reliably produce the most varied formulations with many different raw materials and auxiliaries. The high-performance machine controller records all essential formulation and process parameters for logging and traceability, facilitates data evaluation and so lays the foundation for successful plastics production.

            Gravimetric dosing

            Gravimetric dosing is based on weighing the bulk material to be metered, so weight is the only measured variable. A number of load cells integrated in the dosing system constantly detect the weight of the individual components...

            Volumetric dosing

            In volumetric dosing, material is discharged solely on a volume basis by adjusting the speed of the dosing element, the bulk material present in a material storage bin being supplied to the process. The volume of material to be metered, after...
