4.2 vibration sieve machine. Circle the number of swings (280 ± 10) times/min; up and down rapping frequency (156 ± 5) times/min; noise ≤70dB.
4.3 Balance. a sense of volume ≤0.2g.
5 test procedure
Weigh 100g sample weighing accuracy of 0.2g, sieved using a predetermined test sieve mesh size. 2min or manual sieving through the sieve shaker
Sieve Sieve 1min after mass on matter, to the nearest 0.2g.
