Introduction: Dust angle (or angle of repose) refers to the acute angle between the dust accumulation slope and the bottom horizontal plane. HYL-105-type injection method to limit the bottom surface Saber is Dandong City Hao Yu Technology Co., Ltd. based on national standards GB / T 16913.5-1997 (This standard reference with ISO 4324: 1997 Powdered and granular surfactant - powder and Particle - determination of angle of repose) of the provisions of the design, production. This device is suitable for the determination of dust objects, the use of injection limited floor method for determination of dust angle, and ISO 4324: 1997 The main technical difference is not measured on the accumulation of dust on the limited bottom surface and the use of protractor direct determination of dust angle. 1, the principle Sufficient overflow pan of dust from the funnel port into the horizontal tray; measuring dust accumulation slope and the bottom of the horizontal angle between the folder, that is, dust angle of rest. 2, the instrument structure (a full set of equipment made of 304 stainless steel) (1) funnel (outlet diameter 5mm) One funnel taper 60o ± 0.5o; (2) protractor Protractor 10cm; (3) chassis Outflow bottom and the distance from the disk 80mm ± 2mm, tray diameter Φ80mm. (4) Repeatability error ≤1%.
