Re: Guidelines For Handling Sticky Materials
You might try Lyn Bates of this forum and his company Ajax, Dr. John Carson, at Jenike and Johanson, Dietmar Schultz, or Dr. Peschel, as well as many others who have repeatedly published and contributed to this forum.
Your question has many parts:
1. classification of the mineral physical properites in a laboratory
2. need for an appropriated confined and unconfined stress flow measurements with moisture and granular size which is given in rheology terms.
3. comprehensive rheology based mathematical modeling tool, that incorporates points 1 and 2 to guide your understanding of the flow mechanics given you have determined the necessary properties and can resolve the stresses
4. there are chemical, and molecular based interactions between very fine particles for which you might study the claims of manufactures of instruments that are used to define the physical properties such as made by Malvern and Coulter. There is much more to fine particle physics than a simpilfied J&J formulation.. ■

A: Have a look at issue raised by Notso25 called Sticky Material Handling ; you might find people there who have contributed who can help you. ■
Design Guide For Sticky Material
Dear Mr. Ash,
For proper flow you must use aeroslide in the bins/bunkers. I suggest to visit site of CLAUDIUS PETERS.

Re: Guidelines For Handling Sticky Materials
This is the first time I've heard of air slides being used on "sticky materials"
Unless we have different interpretations of "sticky materials" ■
Re: Guidelines For Handling Sticky Materials
Dear Sir,
Airslide is a perforated plate attached to the conical portion of bin. Air at 6 bar is passed through it so that material would not come into the wall resulting smooth flow. I am using in the lime bin/silos.

Guidelines for Handling Sticky Materials
I am preparing a document 'Design guidelines-for hoppers, chutes, storage etc. for sticky material handling' like gypsum,clay etc.
pl let me know the information data base for this e.g some papers, technical writeup etc. ■
