Hosokawa Micron Powder Tester Characteristics PT-R
The Powder Characteristics Tester, Model PT-R, is a single instrument which provides seven mechanical measurements and three supporting measurements of dry bulk powders. It complies with Standard Test Method ASTM D6393-99 Bulk Solids Characterization by CARR Indices. It has been developed to improve handling, efficiency, and accuracy in testing the bulk properties of dry powders.
The primary functions of the PT-R device are to provide: measurements in a single convenient unit; an additional basis of data for quality control of powdered products; and numerical evaluations of flowability and floodability of powders. The Powder Characteristics Tester features a microcomputer, electronic balance, a data printer, and a built-in dust collection system.
Bulk materials have inherent properties including particle size distribution, bulk density, particle shape, surface area, moisture content, cohesiveness, hygroscopicity, etc. Especially important is the flow behavior (flowability) and the flood behavior (floodability), of powders during production and in their respective application uses.
