Pulp and Paper Manufacturing Process in the paper industry

The dilute slurry is then cleaned in cyclone cleaners and screened in centrifugal screens before being fed into the 'wet end' of the paper-forming machine. The dilute stock passes through a head-box that distributes the fiber slurry uniformly over the width of the paper sheet to be formed.

Optimizing your SAG mill operation

Mar 21, 2021Similar to slurry flow-back, the pebbles flowing back into the mill increase with larger pebble port or grate slot size. As the pebbles flow down and slide across the grate slots, they get an equal chance to go back into the mill. Similar to slurry pool formation, pebbles flow-back would increase the quantity of critical size material in the mill.
