Abstract

The invention discloses an on-line particle image particle size analysis device, which comprises a sampling container, a sampling compressed air pipe, a sampling pipe, a material dispersion connector, an air compressor, a high-speed image pick-up device, a powder return pipe and an upper computer, wherein granular materials fall into the sampling container, are sucked into the sampling pipe, and are conveyed into the material dispersion connector through the sampling pipe; compressed air generated by the air compressor is introduced into the material dispersion connector; the materials in the material dispersion connector are blown away by the compressed air; the materials with uniform thickness fall into a high-speed image pickup region; a high-speed camera performs high-speed photo taking on the dispersion materials fell in the high-speed image pickup region; the particle graduation of the dispersed materials is recorded; the upper computer collects images shot by the high-speed camera; the shot images are analyzed through particle analysis software; the specimen particle size distribution condition is obtained. The on-line particle image particle size analysis device has the advantages that the concentration influence of taken materials is avoided; the measurement data precision is high; data such as morphological parameters can be obtained.

Description

technical field [0001] The invention relates to the technical field of analytical instruments in cement production quality control, in particular to an online particle image particle size analysis device for analyzing the particle size distribution of dry particles. Background technique [0002] Particle size distribution refers to the percentage of particles with different particle sizes in all the particles that make up cement. The determination of particle size distribution is not only an effective method to control the fineness of cement particles, but more importantly, it provides a basis for preparation for the optimization of grinding, grading and other links. The particle size distribution of cement will greatly affect the strength of concrete, the measurement of particle size distribution can control the quality of the final concrete, and how to optimize the production process in the production process, improve product quality, reduce energy consumption, and reduce ...
