In the previous procedure, drums were filled with resin and heated up in ovens; then the liquified resin was mixed with another liquid in a stirred vessel. This time-consuming and comparatively cumbersome to master process led to production bottlenecks.
The customer turned to us with its request for a safe, yet, at the same time, flexible work environment. In close consultation between the provider and the user, they agreed to design a flowing and space-saving process.
After the process conversion, the resin granulates will no longer be prepared in drums but rather in bulk bags. The material to be transported is now placed centrally and in the easily reachable material storage above two bulk bag unloading stations. Whereby the bulk bags are alternatingly unloaded and standstill times for container changes are avoided.
Two Volkmann Conweigh vacuum conveyors suck the material from here and transport it over 60 or 85 m distance and 12 m high to the stirred vessel with a conveyor capacity of 2 tons per hour.
The Conweigh systems ultimately supply 100 precisely measured grams of the transported material to the stirred vessel where it is heated and mixed with other liquids.
Now various flammable materials from the client can be safely transported with the selected system. Studies have shown that the suction lines can be almost completely emptied so that additional cleaning measures are not necessary in the case of pending material changes which contributes to the desired high flexibility in the system. The entire system is designed and made in conformity with ATEX.
The client chose the VOLKMANN solution for the new design of the process not least because of the close cooperation and competence specifically found in explosion risk prevention. The proposed solution also appeared attractive on account of the hygienic aspects and the operation and maintenance friendliness.Volkmann considers the user’s needs with knowledge and experience and therefore develops optimal results and processes.
