As an experienced project partner, OAS AG was able to contribute its entire expertise in the targeted expansion of existing production facilities to this project. A total of twelve stainless steel storage silos were integrated into the production plant for the additive dosing station. Three of these silos are specially designed for the storage of hygroscopic raw materials. The silos were suspended in a steel structure. Vibratory discharge trays and dosing screws with quick-release flaps are used to dose the raw materials into two small component scales below the silos with maximum accuracy. The small component silos are filled with big bags and sacks via a raw material platform located above the silos.
The expansion of the existing mixer with a pigment dosing station included the delivery of a bag feed hopper, a dosing screw and a platform scale. The extension allows additional pigments to be stored and precisely dosed into the mixer. This eliminates the need for the operator to manually add pigments to the mixer in batches. Waiting times in the production flow are avoided and quality is increased thanks to consistently high dosing accuracy. Both smaller and larger dosing quantities can be flexibly dosed into the batch mixer in a short time.
Planning and execution were carried out in accordance with ATEX regulations. All electrical work, mechanical work and the steel construction were also part of the OAS scope of services, as was the final supervision of the commissioning of the system by the customer and the training of the employees.
