We are working on testing bulk material for nickel ore raw material, which has a form similar to wet clay and is very sticky. We are experiencing an issue with the drop box calibration testing because it's jammed and stuck at the drain gate. So we couldn't measure the dynamic angle of repose. Is there a simple physical testing material that behaves like mud or wet clay, and is also very sticky.
Thanks in advance for any help or insight on these questions.
Best regards,
