Current Trend in Mechanical Pulping

Abstract

Even there is no movement of new mechanical pulp project in Japan, capacity of mechanical pulp manufacture is still increasing in the world. As main driving force of this movement, cost reduction has been done by various methods ; fewer and larger production units with bigger equipment, process to get lower cost and higher quality, low energy segment and etc.
Even in the existing plants, Metso is working to improve them. One key equipment is mechanical steam separator to improve fiber loss and retention time between two refiners. Adjustable gap sensor instead of conventional TDC sensor is also available now.
