inpact of cyclone size on throughput

  • Cyclone Diameter an overview ScienceDirect Topics

    Cyclone capture efficiency is often defined as cut-off size. The cut-off size is defined as the size of particles that are likely to be collected with 50% efficiency by a given cyclone. Increasing the inlet velocity to the cyclone improves capture efficiency as well as the pressure drop.Cyclone Size an overview ScienceDirect Topics,The most important variable that controls both throughput and upper size limit is the cyclone diameter Dc. The feed inlet diameter Di is typically 0.15–0.25 times the cyclone diameter. The vortex finder (outlet) diameter Do is typically 0.43–0.5 times the cyclone diameter. The apex (spigot) underflow diameter Du is generally 0.3–0.4 Dc.
