Automatic vibratory separator
First Claim
1. A vibratory separator comprising a base, a basket movably mounted on the base and for supporting screen apparatus for treating material introduced into the vibratory separator, the basket on the base and pivotable with respect thereto, screen apparatus supported by the basket, the material flowing onto the screen apparatus for treatment, vibratory motor apparatus connected to the basket for vibrating the basket and the screen apparatus, variable frequency drive apparatus for selectively driving the vibratory motor apparatus at a selected speed, angle adjustment apparatus connected to the basket for adjusting angle of the basket, sensor apparatus connected to the vibratory separator for sensing a parameter indicative of operation of the vibratory separator for providing a signal corresponding to said parameter, and control apparatus for receiving signals from the sensor apparatus, for controlling the vibratory separator based on said signals, and for automatically signalling the variable frequency drive apparatus to change the speed of the vibratory motor apparatus so that force applied to the basket is changed.

Abstract
A vibratory separator and methods for using it, the separator in certain aspects having a base, a basket on the base, motor apparatus for vibrating the basket and screen apparatus thereon, variable frequency drive apparatus for selectively driving the vibratory motor apparatus, and, in certain aspects, angle adjustment apparatus for adjusting angle of the basket; and, in certain aspects, for sensing a parameter indicative of operation of the vibratory separator, and control apparatus for receiving signals from the sensor apparatus, for controlling the separator based on said signals; and, in certain aspects, for automatically signalling a drive apparatus to change the speed of the motor apparatus; and, in certain aspects, the vibratory motor apparatus connectible to the basket at a plurality of locations so that a motion profile of the basket is selectively variable between linear, elliptical, and circular motion.
