GB/T 6609.27 alumina chemical analysis methods and determination of physical performance - Part 27. Particle size analysis by sieving
(GB/T 6609.27-2009, ISO 2926.2005, IDT)
AS2879.6-1995 alumina mass distribution --- electronic screening method for the determination of grain size
3 PRINCIPLE OF THE METHOD
Use wear indexer, under controlled conditions, with a high velocity gas jet alumina samples to wear out, wear measurement sample
Particle size distribution before and after. Attrition Index is under specific test conditions, quality of sample + 45μm part percentage before the abrasion test
After the degree of reduction. Flow instruments available alumina standard samples for calibration.
4 Instrument
4.1 Attrition Index Instrument. As shown, a typical instrument 1, the constituent elements include.
4.1.1 Column. stainless steel, aluminum and glass column, height 1500mm ~ 1600mm, inner diameter of 25mm. To reduce dust adhesion, column
An upper portion of an inner diameter slightly larger than the interface. One kind of the total length of 700mm and 64mm diameter upper portion of the column is also suitable. In any case, the tube
Columns should be maintained above the minimum 200mm from the chassis opening at the inner diameter of 25mm. And these strings when assembled, the connection must be taken
Smooth tapered transition form to ensure that the alumina column is not in residence at the interface. You can also install a timer for automatic string percussion device
To facilitate the tapping column (see 6.2.5).
4.1.2 Orifice. The orifice plate is installed and sealed at the center of the bottom of the column, the central orifice having a diameter of 400μm ± 15μm hole of hard gold
Spp. A typical orifice plate 2 and the correct positioning of the orifice hole can cause small changes in the air flow changes through wear index alumina
Calibration standard sample.
4.1.3 cleaning device. the installation of cleaning and sealing the top of the string.
4.1.4 airflow measurement and control equipment. air flow measuring and control equipment should include components, operating flow measurement and control airflow 5L/min ~
8L/min, accurate to 0.1L/min.
4.2 Balance. a sense of the amount of 0.01g.
4.3 Particle Size Analyzer. electric forming screen and regulations in GB/T 6009.27 in the instrument. Alternative particle size analysis method, see 6.3.
4.4 Sample splitter. provide a representative sample, the rotary separator.
4.5 blowing gas. between 400kPa ~ 800kPa, can provide a stable pressure of dry air or nitrogen.
4.6 Container. can be sealed volume between 60mL ~ 125mL.
