Andritz to provide dewatering technology for Austrian mill
Andritz is to supply a vertical screw thickener (VST) dewatering system, including an MC pump, for the RMP (refiner mechanical pulp) process at Mayr-Melnhof Karton’s mill in Frohnleiten, Austria.
The Andritz VST is a screw press with a vertical design. The pulp is fed in from the top and then compressed and dewatered as it moves downwards. The self-filling and gravity-assisted dewatering principle allows higher throughput and pulp dryness because the available screen area is fully used.
The Andritz system also has a dilution conveyor, MC pump including standpipe and a TurboMix agitator. Automation, instrumentation, engineering, mechanical installation, commissioning and start-up supervision are also part of the scope of supply.
Start-up is scheduled for the fourth quarter of 2020.
