Product Details
ST-F13 Dust Angle of Repose Tester Designed for Determining Angle
of Repose of Dust Using Injection Limited Bottom Method
Resting angle (also known as rest angle): refers to the acute angle
between the inclined surface of dust accumulation and the bottom
horizontal plane.
The ST-F13 powder (dust) angle of repose tester is designed and
produced in accordance with the national standard GB/T 16913-2008
Test Methods for Dust Physical Properties Part 5: Determination of
Angle of repose by Injecting Limited Bottom Method (this standard
refers to the use of ISO 4324:1997 powder and granular surfactants
- Determination of angle of repose).
The measurement object applicable to this device is dust. The
injection limited bottom method is used to determine the angle of
repose of dust. The main technical difference from ISO 4324:1997 is
that the height of dust accumulated on the limited bottom is not
measured, and the angle of repose of dust is directly measured
using a protractor.
The working principle is that enough dust from the overflow tray is injected into the
horizontal tray from the funnel mouth; Measure the acute angle
between the dust accumulation slope and the bottom horizontal
plane, which is the dust settling angle.
Instrument structure
The entire set of equipment is made of 304 stainless steel
