Particle material grading measurement instrument and measurement method thereof

Abstract

The invention discloses a particle material grading measurement instrument and a measurement method thereof. The particle material grading measurement instrument includes a base, a vibration table, sieve boxes, a sieve box cover, weight measurement units, a touch screen and a switch; the vibration table is arranged on the top of the base; the number of the sieve boxes is greater than 2, and the sieve boxes are stacked on the top of the vibration table from top to bottom; the sieve box cover is arranged on the top of the sieve box at the top; the weight measurement units are arranged in the sieve boxes; each weight measurement unit includes a sieve plate, a sensing ring, weight measurement springs, and strain gages, wherein the sensing ring includes an upper annular sheet and a lower annular sheet which are identical, the sieve plate is arranged on an inner ring of the upper annular sheet of the sensing ring; the diameters of sieve holes of the sieve plates of all the sieve boxes are decreasing gradually from top to bottom; the weight measurement springs are connected to the strain gages, the numbers of the weight measurement springs and the strain gages are 3-8, and the weight measurement springs and the strain gages are arranged between the upper annular sheets and the lower annular sheets; and the touch screen and the switch are arranged on a side wall of the base. After the particle material is sieved, the particle material grading measurement instrument can directly measure the mass of the particle material, can avoid errors, and can directly perform sieving analysis and export a grading graph and important data required by a test.

Description

technical field [0001] The invention belongs to the technical field of sieving analysis of granular materials such as geology, metallurgy, chemical industry, construction rock and soil, and in particular relates to a granular material gradation measuring instrument and a measuring method thereof. Background technique [0002] At present, the sieving analysis of granular materials involved in our country mostly uses manual or unilateral machine sieving. After sieving, the granular materials in each sieve box must be manually transferred to the balance for quality measurement. During the measurement process , due to the process of transferring the container is prone to mass loss which leads to errors. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the present invention aims to provide a particle material gradation tester and its test method. [0004] Technical solution: In order to solve the above-mention...
