Foreword

YS/T 438 "sandy alumina determination of physical performance" is divided into five sections. --- Part 1. Determination of particle size distribution by sieving; --- Part 2. Determination of the abrasion index; --- Part 3. Determination of angle of repose; --- Part 4. Determination of specific surface area; --- Part 5. Determination of α- alumina content of X- ray diffraction. This is Part 2. The partial replacement of YS/T 438.2-2001 "Determination of sandy alumina determination of physical performance wear index" This part is YS/T 438.2-2001 "Determination of the physical properties of sandy alumina Determination of attrition index of" amendments and YS/T 438.2-2001 compared to the main changes are as follows. --- Increased precision; --- Increased quality assurance and control of the content; --- Instrument schematic improvements; --- Sample drying temperature is "300 ℃ ± 10 ℃" changed to "105 ℃ ± 5 ℃".

3 Method summary

The sandy alumina sample is divided into two parts, part of the sample directly measured -45μm screening size fraction mass fraction; another part of the test Like in the fluidized bed at a constant air circulation blowing the wear and sieved grain size was measured -45μm mass fraction. According to the two parts Level content changes -45μm grain sample is calculated wear index of the sample.
