Abstract

The invention discloses a tester and a method for automatically and quantitatively testing the flowability of particle material, which consists of a mechanical part, a microcomputer test system hardware and a soft ware, wherein, the mechanical part comprises a material storehouse, a machine frame, an automatic flow conveying part, a vibrating conveying part and weighing stand. The invention aims at determining the flow speed and the flowing flux changing rate as the dynamic evaluation index of the flowability when the particle material is under the natural flow in gravity effect and the conveying flow in the external force, and then realizing the analysis of the automatic constant flowability of particle material according to the flow speed and the flowing flux changing rate under the twoconditions. The invention can measure the stability and speed of flow of different particle material in the different environment and plant constructional material, further analyze the effect of the material characteristics, the environmental factor and the constant device on the flowability of particle material, therefore, the invention provides theoretical basis and experimental data for studying the automatic quantitative and increasing the automatic quantitative performance.

Description

technical field [0001] The invention relates to an automatic quantitative fluidity testing device and method for powdery material, which belongs to the technical field of material characteristic detection and is used for measuring the stability and rapidity of the flow of powdery material during the automatic quantitative process. Background technique [0002] In the process of automatic quantification of powder materials, operations such as conveying, feeding, weighing, filling and feeding of materials are required. Due to the variety of powder materials and the different physical and chemical properties of the materials, they show different fluidity, and the fluidity of the material will change with the different production environment, conditions and equipment structure materials. The fluidity of materials is different or changes, and the speed and stability of material delivery or feeding are different during the quantitative process, which will affect the quantitative s...
