PFT Powder Flow Tester
The PFT Powder Flow Tester provides quick and easy analysis of powder flow behavior in industrial processing equipment. It is ideal for manufacturers who work with powders daily. By altering the composition of the powder sample, flow properties can change, and these changes are quickly and clearly detectable using the shear cell method. The flow characteristics of the tested material can be compared with those of known materials.
