Grain size rougher than 120#, use sandblasting hardness tester;
Grain size finer than 150# use chromium hardness machine to test;
We can also use hand cone method, steel scraping method,
according to the hand cone or scratch to recognize roughly.
use a balance instrument for static or dynamic balancing test,
