Novel building powder angle-of-repose testing device and using method

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 impu
