Cyclones Don't Do Any Grinding

Oct 10, 2017The answer is the cyclones shouldn't be used to try and control grind. The major factors that influence the grind-size are the feed PSD, ore characteristics (both the coarse breakage (Axb/DWi/WS AG etc), and fine grinding (BWi) parameters), grinding power, grinding media, classification efficiency and throughput rate.

Engineering Controls Database

Grinding and pulverizing the ore is performed later in the mineral process to reduce the product down to the smaller size ranges, normally measured in mesh sizes. Grinding mills are used to perform this process and are cylindrical, horizontal drums that rotate and have rods, balls, or pebbles inside to grind the ore down to the desired size ranges.
