Abstract
A segmented screen body or bottom for classification, screening and washing of fragmented hard stocks employs a multiplicity of segmented elements constructed of elastomer or rubber material which, when abutted and supported in predetermined relations, define sieve apertures of a predetermined size and extending, if desired, in staggered longitudinal rows. The structure further requires a multiplicity of parallel transverse metal wires or equivalent elements which are embedded and extend through appropriate apertured portions of the elastic components. In the preferred form the essential elements include T-shaped and L-shaped elements, all of which may be obtained from identical integral moldings of T-shape and many of which are cut along transverse lines at the T-top to provide from the same moldings complementary L-shaped elements.
Claims6
A segmented, elastic screen body having in combination:
- a muliplicity of discrete, complemental, elastomer units, having stem-bar portions extending in the direction of flow of the fragmented material to be sifted and having also terminal, integral transverse-bar portions extending perpendicularly to one end of each stem-bar portion,
- said transverse-bar portions having wire-embedding bores extending longitudinally therethrough, said stem-bar portions having transverse wire-embedding bores through the second end thereof,
- said units being arranged and disposed in alternately, longitudinally staggered relation with bores of said transverse-bar portions being aligned transversely of said body with the transverse bores of said adjacent stem-bar portions,
- and a plurality of reinforcing and interconnecting wires extending transversely in spaced relation across said body and each passing through an aligned series of bores of said units.
A segmented screen body for classifying and screening fragmented hard-stock materials having in combination,
- a multiplicity of individual, T-shaped, complemental, aperture-defining units constructed, at least mainly, of elastomer material,
- said units each having a stem-bar portion extending in the direction of flow of the material to be screened and having a transverse T-head portion connected with one end of said stem-bar portion and having a longitudinal support-wire-receiving bore therethrough,
- said stem portion having a transverse wire-receiving bore through its other end,
- said units being arranged and positioned in alternately staggered rows, with the bores of said T-head portions being aligned transversely of the screen body with the transverse bores of the adjacent stem-bar portions, and
- a plurality of supporting, reinforcing and interconnecting wires fixed and extending in spaced relation transversely across said body and each passing through an aligned series of bores of said units.
