Abstract
A vibrating screen assembly of dissimilar materials. A frame is composed of a first material having a coefficient of thermal expansion. At least one screen cloth is composed of a second material. A ratio of the coefficient of thermal expansion first material to the coefficient of thermal expansion of the second material is greater than one.
Claims19
A vibrating screen assembly, which comprises:
- at least one screen cloth;
- a metal frame of different material from said screen cloth, said screen cloth bonded to said metal frame and wherein said metal frame has a coefficient of thermal expansion greater than a coefficient of thermal expansion of said screen cloth;
- wherein said frame includes a pair of tubular sides, a pair of tubular ends, a plurality of tubular cross members extending between said sides, wherein said cross members are connected together by a plurality of rods;
- and
- wherein the distance between said cross members and the distance between said rods forms a ratio from 0.1 to 1.0.
A vibrating screen assembly of dissimilar materials, which comprises:
- a frame of a first material having a coefficient of thermal expansion;
- at least one screen cloth of a second material having a coefficient of thermal expansion, said screen cloth secured to said frame;
- wherein the ratio of said coefficient of thermal expansion of said first material to said coefficient of thermal expansion of said second material greater than one;
- wherein said frame includes a pair of tubular sides, a pair of tubular ends, a plurality of tubular cross members extending between said sides, wherein side said cross members are connected by a plurality of rods;
- and
- wherein the distance between said cross members and the distance between said rods forms a ratio from 0.1 to 1.0.
A method of manufacturing a vibrating screen assembly, which comprises:
- assembling a frame of a first material having a coefficient of thermal expansion, said frame including a pair of sides and a pair of ends wherein said frame includes a pair of tubular sides, a pair of tubular ends, a plurality of tubular cross members extending between said sides, wherein side said cross members are connected by a plurality of rods;
- wherein the distance between said cross members and the distance between said rods forms a ratio from 0.1 to 1.0;
- placing a high temperature adhesive on said frame;
- tensioning at least one screen cloth composed of a second material having a coefficient of thermal expansion less than said frame;
- and
- adhesively securing said screen cloth to said frame.
