Abstract
A new and improved nonadjustable self-cleaning dewatering screen panel assembly suited to vibratory dewatering of fluid slurries containing fine particulate solid material is comprised of a rigid frame member and a substantially planar screen panel mounted within the frame and secured thereto under tension in both planar directions. The screen panel is a unitary one piece elastomeric sheet consisting of a plurality of pulsator portions and integral bordering stabilizer portions. The pulsator portions of the elastomeric panel are comprised of a multitude of substantially identical diaphram elements arranged in intimate, aligned and confronting relationship so as to present a smooth top screening surface. The diaphram elements are of uniform cross section throughout their depth and define a column of spaced parallel slits between individual abutting elements to permit limited, random, harmonic and pulsating motion of the flexible elements within the plane of the assembly in addition to the vibratory motion of the assembly. The screen panels may also be used for classification by size of particles in the range of 10-50 mesh.
