Abstract

The invention discloses a novel building powder angle-of-repose testing device and a using method. The novel building powder angle-of-repose testing device comprises a control mechanism, a measuring mechanism, a supporting mechanism and a material conveying mechanism. The supporting mechanism is used for supporting the control mechanism, the measuring mechanism and the material conveying mechanism which are arranged on the upper portion. The control mechanism is in communication connection with the supporting mechanism and the material conveying mechanism. According to the novel building powder angle-of-repose testing device, the angle of repose of powder can be automatically worked out according to height and diameter data, and the defects that in the prior art, manual operation repeatability is poor, and testing precision is not high are avoided. To further guarantee the testing process precision, a dust cover is arranged on the upper portion of a material storage barrel, and pollution caused by mixing impurities is avoided. The material storage barrel is made of high-intensity FRP, and the state of the powder inside the material storage barrel can be observed in real time while the supporting intensity is guaranteed. The whole device is compact in structure, less space is occupied, the device is convenient to move when not needed, and angles of repose of all kinds of powder can be tested conveniently.

Description

technical field [0001] The invention relates to a measuring device for construction, in particular to a novel construction powder material angle of repose testing device and a using method. Background technique [0002] The angle of repose refers to the angle between the generatrix and the bottom plane of the cone formed when the granular material falls naturally and continuously from a certain height onto the plane. The angle of repose is an important part of determining the shear strength of powder materials, and the angle of repose reflects the internal friction characteristics and scattering properties of granular materials. When the material on the inclined surface of the cone has its gravity component force along the inclined surface equal to or less than the internal friction between the materials, the material particles will stand still on the inclined surface. The larger the angle of repose, the larger the internal friction and the smaller the scattering. [0003]...
