Accurate consistency control at Papeleras del Arlanzón’s OCC line


Previously, Papeleras del Arlanzón in Burgos, Spain, did not have consistency measurements in their OCC pulper and refiner line. This caused consistency variation, and consistency control was not possible. Immediately after the latest generation Valmet Blade Consistency Measurement (Valmet SP) was launched, they installed measurements in their pulp circuit. Since then, operators have been able to achieve the right pulp consistency values and process quality and stability have improved in the PM2.
