Reliable refiner consistency control with Valmet MCA
May 30, 2022
Papelera Guipuzcoana de Zicuñaga in Spain installed a Valmet Microwave Consistency Measurement (Valmet MCA) in their refiner's feeding line. They use a mix of hardwood pulp, softwood pulp, and calcium, and needed a measurement that could measure the consistency accurately and without a risk of being damaged by particles or wires in the pulp.
It is the first microwave consistency transmitter installed in the mill and the results are very promising. It is a very trustworthy and consistent measure despite changes in the mix. The setup and calibration were easy and well explained. This is a good upgrade from a blade transmitter, and we expect a very long lifetime due to the absence of wear parts compared to rotative transmitters.
