Abstract

See full text

An apparatus includes a screen basket and a drive system coupled to the screen basket. The drive system includes a motor and a drive having a drive shaft. The drive system imparts a gyratory motion to the screen basket. First and second eccentric masses are coupled to the drive shaft. A method includes coupling the drive system to the screen basket of a sifter; the first eccentric mass positioned a distance above the second eccentric mass. The first and second eccentric masses are rotated together. The masses of the first and second eccentric masses are provided and/or adjusted so that a summation of forces generated by rotating the first and second eccentric masses generates a force line in plane with a center of gravity of the sifter. Rotation of the eccentric weights may move a distal end of a first and/or second weight arm a vertical distance upward.
