Coefficient of Friction - Avalanche Angle

We have a instrument that gives a quick check of your powders’ flow behavior.   Watch our u-tube

video for a simple view of how it works and what you get to see during a test.  We can vary the speed of rotation.

Remember the important variables

Many vendors are offering various flow tests and compression tests to evaluate processability of powders.  There probably isn’t a single test that tells the whole story.

A good starting point is the Avalanche Angle Cruiser - to let you visually observe and identify the key attributes affecting flowability.

You can vary the speed of testing and get the angle of avalanche at each set of conditions.
