The well-known formulae of screening efficiency and circulating load calculations in closed crushing circuits were exploited to achieve graphical estimation of these parameters. Three basic charts were proposed and constructed. The first one is for the regular closed circuits where the new feed goes to the crusher. The second is for the reverse closed circuits in which the new …

As such, the pressure drop used for determining the d 50(c) is applied to determine the feed flow rate per cyclone. To determine the number of cyclones needed, the total flow rate of the stream is divided by the allowable flow rate per cyclone (see attached graph). The data shown in the graph was obtained using water.

Buoyancy. The drilling fluid types provide a beneficial effect relative to drill string weight or hook load. The mud system supports or buys some of the pipe weight when the drill pipe is lowered into the well. This effect is termed buoyancy or buoyant forces. The buoyed weight of the drill string will be less than the in-air weight of the pipe.
