Abstract
A vacuum assisted drill cuttings dryer and handling apparatus has a vacuum tank and an associated vacuum pump and motor configured for use with a high speed centrifugal dryer. Cuttings are drawn from the shaker of a drilling rig into the centrifugal dryer by means of a vacuum created in the centrifugal dryer by the vacuum tank and an associated vacuum pump and motor. The dryer is provided with sealable exit doors that may be opened and closed in sequence to allow removal of the cuttings even as cuttings are drawn in to the centrifugal dryer. A fluids collection chamber in communication with vacuum lines between the vacuum tank and centrifugal dryer collects fluids drawn from the centrifugal dryer.
