System for testing performance of solid particles under rolling state

Abstract

The invention discloses a system for testing the performance of solid particles under a rolling state. The system comprises an extruding and wearing device, a sieving device, a recovering and fillingdevice and a feeding device, wherein the extruding and wearing device is used for simulating the character of the solid particles under the rolling state; the sieving device is used for filtering gravels and conveying the unfiltered solid particles to the recovering and filling device; the recovering and filling device fills the feeding device with the solid particles; the feeding device feeds thesolid particles into the extruding and wearing device to form circulation. The system disclosed by the invention has the advantages that (1) the experimental cost is low, the simulation degree is higher, and the tested experimental data is real and reliable; (2) the experimental system can work for long time, the speed is adjustable, the experimental mode is more flexible, and the experimental purpose can be changed by a mode of replacing different counter weights and materials; (3) the solid particles can be recovered for secondary experiments, so that the material utilization ratio is increased; (4) a collecting box is arranged for collecting the solid particles in an unified manner so as to keep a clean environment for test work.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a system for measuring the properties of solid particles in a rolling state. Background technique [0002] The wear resistance and rolling resistance of solid particles often determine their performance. Accurate and true measurement of the wear of solid particles under complex stress conditions in the working state is of great significance to earthmoving machinery and equipment. The testing machine designed in the prior art can only solve the test of a single metal, and there is no performance test for solid particles. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a system and method for measuring the performance of solid particles in a rolling state, which can effectively solve the above-mentioned problems in the prior art. [0004] In order to realize above object of the invention, the technical sche...
