MT 178.2 - Attrition resistance of dispersible granules

Content Handbook K


Outline of method

Prior to the test the granules are sieved on a 125 µm sieve in order to remove fine particles. A known amount of this dust free granules is transferred to a glass bottle and is then subjected to a rolling movement. After rolling for a specified period of time the attrition resistance is determined by sieving again on a 125 µm sieve and weighing the material remaining on the sieve.
