The ERWEKA Granulate & Powder Flow Tester, Type GTB, combines the functions of determination of the knowledge of the important flow properties with the measurement of the angle of repose:
- Determination of the flow time of a
For determination of the angle of repose the sample is passing through a funnel located at a predefined height above a circular plate thus forming a gravimetric cone. The angle of this gravimetric formed cone is determined optically (laser) and documented.
Where samples exhibit poor flowability, the hopper is available with a stirring device with variable speed control.
The GTB is handled by alpha-numeric membrane keypad, results are shown at the illuminated 320 Digit 16-line full-graphic LC display.
As standard the unit is delivered with a stainless steel hopper (480 ml) and three stainless steel outlet nozzles (10; 15; 25 mm) which can be exchanged by a quick coupling. Additional stainless steel hoppers (100; 200 ml) and outlet nozzles (6; 8; 11.3 mm) are available as option.
The GTB comes with serial RS 232 and parallel printer
interface for transfer and print-out of results.
The OQ Tool-Kit comprises of all needed instruments including a PVC cone to check the accuracy of the laser measurement device for the angle of repose.
