摘要： A vertical cuttings dryer (“VCD”) can be used to separate solid particulate from entrained liquid. In some examples, the VCD includes a screen mounted coaxially with an internal wiper housing that carriers a wiper sweeping out an annular space between the screen and wiper housing. The VCD may have a first motor connected through drive shaft to the screen and a second motor connect through a separate drive shaft to the wiper housing. A controller can independently control the speed of the first motor and the second motor to independently a magnitude of centrifugal force applied to material being processed as well as a residence time of the material being processed in the annular space.
