A complete range of spirals for minerals concentration
Proper distribution is normally achieved using a spiral slurry feed distributor. Standard distributors divide the feed into 12, 24, 36 or 48 ways. When selecting a distributor one should be chosen which is closest to the number of spiral starts to be operated. The plumbing to each spiral concentrator should be
Spiral conditions for the recovery of ultra-fine …
Spiral separators for the recovery of ultra-fine particles have a unique profile, pitch and features to ensure it performs efficiently. The flow on the spiral trough must be controlled to minimise turbulence that will entrain fine particles in the outer section of the trough. Keywords: Ultra-fine particles, spiral, design, recovery 1. Introduction
