Pulping section: High viscosity, low concentration
Thread Content
In the pulping section, the viscosity is high while the concentration is low. Could everyone please tell me what’s going on here? I would appreciate your advice.
Possible reasons: 1. The selected additive is not suitable; replace it through experiments； 2. Changes in coal type affect the factors influencing slurry formation ； 3. There is an issue with the ratio of coal grinding rods; the proportion of fine rods is too high ； 4. High pulping capacity but low output ；
Try adding a few more additives and see
With no changes in coal quality or additives, there are just too many fine rods.
Is the viscometer giving inaccurate readings?
1. Amount and concentration of additives 2. Check whether the grinder steel rods are ground fine
There’s no data, so we can only guess. Let’s take a look at the analysis data
The analysis on the 2nd floor is quite comprehensive; one can go to a specialized institution to test the slurry-forming properties of the coal
