Reliable refiner consistency control with Valmet MCA
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.
|Challenge||To measure reliably the consistency of mixed pulp flow that might contain wires from the softwood pulp bales and has different degrees of ash content and hardwood/softwood mix.|
Valmet Microwave Consistency Measurement (Valmet MCA) to replace a blade consistency measurement.
A Flow Through model was selected as there is a risk for metal wires of pulp bales.
Delivery contained also Valmet Nove Sampler to assure reliable sample taking.
