SCREENING OF PULP |
摘要 |
A method of controlling the screening process at the screening of cellulose-containing pulp suspensions in a screening device (1) where ingoing pulp suspension (2) is divided by means of a screening member into an accept fraction (3) and a reject fraction (4). The material concentration in the reject fraction (4) is measured continuously by a meter (5) and transferred to a signal (6, 7), which is utilized for controlling the ingoing pulp concentration and/or the energy supply to the screening process. |
