1 Scope
This section GB/T 30202 specifies the size measurement principle desulfurization and denitration of coal for granular activated carbon (hereinafter referred to as active coke), measured
Given the steps and the results of calculation content.
This section applies to the determination of activated coke particle sizes.
2 Principle of Measurement
The sample was placed on a certain quality of a particle size analyzer (vibration sieve) on sieved to remain on each sieve layer and the chassis of the sample mass fraction
Number indicates the particle size distribution.
3 instruments and equipment
3.1
sieve shaker speed 280r/min ~ 320r/min, round trip 25mm, this test does not use slap function.
3.2
Balance, dividing the value of 0.1g.
3.3
Test sieve, phi200 × 50-1.4/0.71; phi200 × 50-3.15/1.25; phi200 × 50-5.6/1.6; phi200 × 50-6.3/1.8; phi200 ×
50-11.2/2.5.
3.4
electric oven, 0 ~ 300 °C.
3.5
brushes, ordinary bristle brush.
4 Sample preparation and
The sample was reduced to about 2000g, placed (150 ± 5) °C in electric oven, the dried 2h, out into the dryer to cool spare.
5 measuring step
5.1
Based on technical requirements, select a set of corresponding test sieve layer, according to the mesh size, top-down order, placed in the vibrating screen on board.
5.2
of dried sample 500g ± 2g, accurate to 0.1g, into the test sieve, sieve shaker will start in a state without rattling, screening
3min.
5.3
turn Gently remove each sieve layer and the layer of each sieve plates with samples were collected. It will be embedded in the sample gently vibrating sieve or under
Brush, it is also to do the screening screen layer.
5.4
each in turn weighed sieve layer and within the chassis screening quality, accurate to 0.1g.
6 calculated results
I-layer particle mass fraction wi count, the results expressed in%, according to equation (1).
