Commercial Hammer MIll Grinding Machine

The screen is located in the bottom half of the hammer mill chamber, covering an arc of about 180°. Milled material exits the mill below the screen. For finer particle grinding and to aid the movement of finer particles thru the mill screen and away from the mill, a separate air transport system can be configured from the discharge of the mill.

The role of sulfidity during kraft pulping - Pulp and ...

The sodium sulfate is not the active chemical during the kraft pulping process but only the source to generate sodium sulfide (Na 2 S). Most of the sodium sulfate in the recovery boiler is reduced to Na 2 S. The efficiency of this reduction is called reduction efficiency and normal values are in the range of 90–94 per cent.
