Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes).
Minerals processing: Be wise and optimise the thickening process
Thickener rake. Over time, a thickener's electronics can drift and decalibrate from simple general wear and tear. So whether a thickener is performing a revised duty or needs fine tuning due to excessive wear, torque loads and drive mechanisms should be audited to determine if the current mechanism configuration and design are adequate.
