Measuring Degree of Mixing Homogeneity of powder mix

Measuring Degree of Mixing - Homogeneity of powder mix ...

Almost all powder mixtures will have a degree of inhomogeneity. The 1st thing to do is to determine the tolerances which are exclusively dependent on the application for which the mixture is intended. Tolerances can be defined internally, or externally by a regulation or a customer. Example 1 : The mixture is used internally for an other unit ...
