(Naturally capacity and performance of all PC’s and plcs have improved exponentially since this line was originally conceived – the world has progressed from computers with MS-DOS through to the world today with PC’s with ever increasing speed and huge memory capacity plus of course, the Internet)
The first Schulman complete extrusion line project which we finished last year, was to replace an old instrument based panel on a Farrel compounding system producing (4) tonnes per hour of masterbatch. As soon as that control system was in place the feedback from ALL of the line operators was extremely positive.
They really appreciated the ease of operation and the logical interface, which was provided by a single Siemens operator panel (HMI) controlling every single aspect of the complete line from extruder heating zones, through to screen changer and underwater pelletizer. Schulman were keen to replicate the success of the BSG ONE operator interface and decided to install a complete extruder control system for one of their twin screw extruders. This control system was retrofitted onto the twin screw extruder on schedule within the two week summer shutdown. BSG Engineers provided installation and commissioning support, with all functions being tested and I/O check (Inputs and Outputs) completed before the complete new operator control was handed over to the production team.
