Many new centrifuge users are wondering: why our solids control centrifuge can treat mud 20m3/h, while the drilling waste management decanter centrifuge http://www.kosun.us/solids-control-equipment/decanter-centrifuge.html can only treat 10m3/h? And the drilling waste management centrifuge is high standard than solids control centrifuge? To understanding this question, we should know the definition of max. solids discharge rate first.

If the solids content is 15%, the max. mud input should be less than 20cbm per hour. And for VFD centrifuge, in order to get better separation result, the bowl speed and conveyor speed should be adjust accordingly. For the same mud input with the same decanting centrifuge, the better of the separation, the smaller of mud capacity. Besides max.hydraulic capacity, there is another figure beeb used together to definite centrifuge performance, it is called the max. solids discharge rate.Definition of max. solids discharge rate.It means the max. solids a centrifuge can discharged per hour. It is from mud test. Let’s say, if a centrifuge can treat max. 30m3/h mud with 10% solids content. It means the max. solids discharge rate is 3m3/h. It means in any cases, the centrifuge can discharge solids no more than 3m3 mud per hour. So the higher of the solids content, the smaller of the mud input (mud capacity).

Decanter centrifuge separates by the work principle of centrifugal sedimentation. The drilling fields usually apply spiral settling centrifuge which works on the basis of different component densities. It mainly removes 2~10μm solid phase from the mud as the last stage in solids control system. It has shared applications in both weighted and unweighted drilling fluids.

Effective separation in unweighted low-solids drilling fluids involves centrifugation and the required centrifuge which is usually large-capacity centrifuge dealing with 23~45m3/h of fluids and 3~4t solids. Drilling fluids will go into two flows in centrifuge, one of which is underflow discharging useless solids to waste pool and another overflow returning valuable fluids to mud tank. Now, centrifuge is riding a wave of popularity in purifying unweighted drilling fluids which carries enormous benefits.
