PVC combined system: more efficient mixing

A specialist in the construction of plastic and powder coating mixing solutions, Promixon counts TMX turbomixers among its lead products. The turbomixers are single or combined with the CMX high performance horizontal coolers, and the TRX high speed mixer containers, for fast mixing of power coating, additive, colour, masterbatch, plastics and engineering polymers.
The combination of TMX turbomixer and CMX horizontal cooler makes the Problend-TC system for the production of PVC-based rigid and plasticized dry blend and PVC/PP/PE WPCs (Wood Plastic Composites). The system was designed to solve problems encountered in these types of production, where excellent mixing quality, where possible with low cost operation, high hourly output rates and reduced wear and maintenance are vital. "We have acquired more than twenty years of experience in this field, and we do not want to settle for standards in use. Instead we constantly aim to propose new technical improvements to our customers' advantage. Everything we do is for their benefit and service", Marco Marinello, general manager for Promixon said.
The Problend-TC system introduces numerous technological innovations. For the TMX turbomixers, the new tank and outlet geometry, fully redesigned and now bigger, speeds up the material unloading step, guaranteeing higher output and preventing deposits of material or residue at the end of the process and consequent contamination. The innovative design of the mixer equipment permits greater friction and mixing intensity, while new anti-wear coating guarantees longer life.
In the CMX cooler, the new tank and mixer geometries intensify the material's contact with the exchange surface, notably improving cooling efficiency. The water distribution circuit inside the tank jacket, designed with an innovative wave configuration, has reduced cooling time by approximately 50%. The special mirror finish of the parts in contact with the material and adoption of some specific solutions simplifies and speeds cleaning and maintenance.
The control software and latest generation HIM Siemens operator panel manages and displays the mixing cycle information in real time, offering features such as data saving and special graphics for process analysis and optimisation. Remote assistance directly accesses the control system to resolve any problems that may arise and to modify process parameters in real time.
