I’ll try the technique you’ve mentioned, hope my guess is correct, we’ll see

Most clays are alkaline, so it maybe a reason for volcano

Thank you Bob!
You are one of the most knowledgeable contributors here and always helping out, just want to thank you a lot!
I’ve checked the Powder & Bulk Solids magazine - pretty good source, although kind of hard to navigate.

Hope you don’t mind another question re equipment.
I spoke to several equipment engineers (Hosokawa is extremely helpful!) and started to worry about pulverizing in hummer mill after binder incorporation. Most of them said that the mesh can get clogged if powder is sticky.
Have you ever experienced this problem with hummer mills? We are planning to buy another mill soon, so I am thinking if there is an advantage of pin mill over hummer mill? (Cannot go with jet type due to it’s power/pressure requirements)
