Pharmacopoeia Sieve Standard sieve (also called test screen, the standard test sieve, sieve particle size analysis, particle size calibration screen, check the screen size, sub-sample screening), test screening test for the metal wire braid and metal sieve GB6003.1-1997 perforated plate test sieves GB6003.2-1997, the same as with the international standards ISO3310. . Mounted on slap-type test sieve shaker (Tyler analysis of vibrating sieves and the United States (rotational separation sieve) Ro-Tap RX-29, RX-30 on the same principle) or standard screen machines used for a variety of powder materials, grain composition degree of classification. Widely used in abrasive, ground Kan, metallurgy, pharmacopoeia, chemical and building materials industry, materials, accurate particle size screening and detection. Product Model: Φ200 * 50, Φ200 * 25. The same time, our company also produces standard test sieve with φ200 supporting slap-style testing sieve machine, the standard sieve machine (Xiangjian product description). Rattling-type testing sieve machine, the standard screening machine in line with national standards and can be installed up to the standard 8-layer screen, equipment, equipped with a timer can be shut down from time to time to ensure that each production or testing consistency. My test sieve produced large-scale use in the diamond industry can meet the user to replace imported sieve.
