Ans - A laboratory tool called a granule friability tester is used to evaluate the granular material's physical integrity. It gauges the granules' resistance to damage from mechanical forces such abrasion, deformation, and friction.
Ans - Granule friability testing can offer useful insight into a material's physical characteristics, such as its resistance to breaking or fragmenting. This information aids in determining the ideal conditions for handling, processing, and storing the material as well as if it is appropriate for a given application.
Ans - The test material is put into the tester and put under a regulated force, like vibration or rotation. An indicative of the sample's integrity is measured as it moves through the tester.
Ans - The rotating drum tester, which mimics the mechanical impact on the sample with a spinning drum, is the most popular kind of granule friability tester. Vibrating testers and impact testers are other tester kinds.
Ans - The tester should be calibrated once a year or immediately following any significant changes to the material or test conditions. This might help to guarantee the validity and accuracy of the test results.
