SUPERIMPOSED MOTION DRIVE

摘要

A vibratory separator including a frame, a screen configured to connect to the frame, a first actuator coupled to the frame, and a second actuator coupled to the frame, wherein the first actuator imparts a high frequency motion to the frame, and wherein the second actuator imparts a low frequency acceleratory motion to the frame is disclosed. Also, a method for processing drilling waste including imparting a low frequency acceleratory motion to a frame of a vibratory separator and imparting a high frequency motion over the low frequency acceleratory motion is also disclosed.
