The Φ75 mm electroformed test sieve is mainly used for precise screening and testing of fine particles. It is widely applied in geological exploration, metallurgy, abrasives, building materials industries as well as particle size analysis in universities and research institutes. Manufactured in accordance with international standard ISO 3310-3:1990, its aperture sizes range from 500 μm to 5 μm. The sieve mesh is produced by electrochemical forming, while the sieve frame, lid and receiving pan are fabricated from high-quality stainless steel.

The Φ75 mm electroformed test sieve is specially designed for particle composition inspection of superhard materials, complying with international standard ISO 6106-79 and national standard GB/T 6406-1996 (Superabrasives — Grain size of synthetic diamond or cubic boron nitride).
