Papermaking Papermaking Processes for preparing pulp: Mechanical or groundwood pulp is made by subjecting wood to an abrading action, either by pressing the wood against a revolving grinding stone or by passing chips through a mill. The wood fibres are separated and, to a considerable degree, fragmented. Chemical wood pulp is made by cooking wood chips with chemical solutions in digesters ...

The black liquor is concentrated and burned to regenerate the pulping chemicals. Because unrecovered sodium and sulfur are replenished by adding sodium sulfate, the process is often called 'sulfate pulping.' Sulfate is not the active pulping chemical, however, because organic carbon reduces it to sodium sulfide when the black liquor is burned.

Oct 01, 1994 · Also, grinding rolls can break up salt to make a fine particle generally termed flour salt. This was originally developed to mirror the size of wheat flour, about 70 mesh, and it usually contains an anticaking agent. If the flour salt is formed with grinding rolls, it no longer has a regular cubic form.
2. Use a 400 ml beaker to obtain about 300 mL of Sodium Sulfate. (DO NOT DISCARD THIS SOLUTION AT THE END OF THE EXPERIMENT. IT WILL BE RECYCLED.) Obtain two of the small rubber bands. 3. Clean two of your smallest test tubes. Slip one rubber band onto each tube. Pour some of the Sodium Sulfate solution into cach of the cleaned test tubes.
