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

Sandy alumina determination of physical performance
Part 2. Determination of attrition index
1 Scope
This section provides sandy alumina in a fluidized bed to determine the wear its attrition index method.
This section applies to the determination of sandy alumina abrasion index.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.
Determination of particle size distribution of sieving. YS/T 438.1 sandy alumina determination of physical performance - Part 1
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.
