How to do sieve analysis testing?

This article is only explained through the conventional dry sieving sample analysis method, and the specific sample analysis and test methods should be strictly followed by industry standards!

Analytical Test Sieves usage: No. 1-8 sieves (full set of sieves)

Analytical Test Sieves Diameter: 200mm

Experimental sieve machine: standard laboratory sieve machine (0-99min timing)

Sample used: Soil

Clean the Analytical Test Sieves before sample analysis to ensure that the sieve surface is free from impurities, clogging and damage.

Weigh a representative sample, and take about 500g of sample to set as the total sample (or according to the industry standard).

Stack the sieves according to the aperture size of the Analytical Test Sieves. The sieve with a large opening (small aperture value) is placed above the small opening (large aperture value), and the bottom end prevents the tray from collecting samples passing through all apertures. #4 and #200 sieves should always be included in the analysis of samples.

Put the weighed 500g sample into the top sieve of Analytical Test Sieves, place it on the laboratory vibrating sieve (the sample together with all the Analytical Test Sieves stacked together), fix the sieve frame, set the analysis time, and start the machine.

After the machine stops running, the sieve frames are taken out one by one and the weight of the sample retained in each sieve frame is weighed.

Sample retention, data recording, and analysis are performed to derive particle size distribution curves.

If you need to perform comparative analysis of different samples, please keep weighing, use the same model of Analytical Test Sieves, and use the same analysis time (control variable) to conduct sample analysis and comparison.
