Study on Ceramic Mud Particle Group Distribution Detection

Abstract

The method combining extinction and scattering attenuation is established based on Beer-Lambert law, Mie theory and multiple scattering theory, It states that high concentrated particle group receiving backscattering light is mainly influenced by particle size, wavelength and refractive index. When processed the sample, our laboratory used the wet ball mill whose working ability is 150kg, and then furnished the material according to the proportion: ceramic material: ballstone: water is 1:1.7:1.So they are 30kg ceramic ore raw material, 51kg ballstone and 30kg water. The ceramic mineral aggregate is made of 6kg coke, 7kg Laiyang soil, 2.5kg blue earth, 1.5kg talc soil and 13kg diopside. Then collected the ceramic mud 500g every hour. In the sample, 200g was used to measure ceramic mud particle group screen residue value by the sieve method. The other 300g was served as sample for backscattering detection. After collecting the sample, continued measuring the screen residue value until the sample screen residue value is lower than 8g. In the sample detection, put the double-D optical sensor's probe into the sample. a optical introduced the light with fixed wavelength 650nm into the probe end, the other optical received the backscattering light. The backscattering light was detected by the detection system, and then disposed with first-order filtering algorithm to get the characteristic curve. The test data stated that in the high concentrated particle group, backscattering light is stronger when the particle group fineness increases, the detected backscattering light is linear with particle group fineness.
