3 Terms and Definitions
3.1 sieve (sieving)
With one or more sieves having different particle sizes of discrete particles size by size material separation process.
3.2 sieve size analysis (sizeanalysisbysieving)
By sieving the sample was divided into different levels of granularity and report the results.
4 Overview
Test sieve is used for screening particulate material having a particle size sieve analysis. It is widely used in geological exploration, metallurgy,
Chemical, pharmaceutical, building materials, abrasive and other industries as well as research institutes particle size analysis and screening tests.
Complete test sieve and covered by a number of different mesh size sieve, splice tray, as shown in Fig. metal
