Abstract

The invention provides an on-line cement particle size detection method. The on-line cement particle size detection method is characterized in that a laser particle size analyzer is arranged in a material conveying chute of a cement grinding powder selector, a signal control box and a analyzer host are arranged to be in electrical connection with the laser particle size analyzer, cement samples in the shape of single particles are blown into a detection window of the laser particle size analyzer, when laser beams emitted by the laser particle size analyzer encounter cement particles in a propagation process, a part of light deviates from an original propagation direction and is scattered to form a scattering angle, a signal representing the size of the scattering angle and the intensity of scattered light which is output by the laser particle size analyzer is converted into an electrical signal by the signal control box and the electric signal is output to the analyzer host, and the particle size and size distribution of cement can be seen in the analyzer host. The on-line cement particle size detection method provided by the invention has the characteristics of rapid and accurate detection, and wide range; and a device provided by the invention can be used for improving the quality and particle size stability of cement after being used, and reducing the waste of energy consumption caused by quality fluctuation.

Description

technical field [0001] The invention relates to a method and a device for online detection of cement particle size. Background technique [0002] Professional research has found that the size of cement particles has a direct impact on the hydration process, and the hydration speed and degree of hydration of cement with different particle sizes vary greatly. Therefore, the detection of cement particle size is very important for cement quality. At present, most of the off-line detection methods are used. When the particle size of the finished cement product is normal, the inspector goes to the site to manually sample once every 4 hours. The test is carried out in the laboratory, and the particle size of the finished cement cannot be monitored in real time; when the particle size of the cement product appears When there is an abnormality, the inspector immediately goes to the site to take samples. It takes at least 30 minutes from manual sampling, inspection to adjustment of pr...
