Screening systems and methods for screening particulate material

摘要

A screening system, preferably a finger screening system, for screening particulate material is provided. The subject screen system includes (a) a screening assembly including horizontally-extending support members located within the confines of the assembly; (b) a plurality of screening modules mounted to the support members and located within the confines of the screening assembly, each screening module having a support block having a plurality of rods joined at a first end to the support block, the second end of the rods being free of attachment, to form a row of the rods arranged substantially parallel to each other and extending outwardly from the support block, the row of rods defining an array of sieve openings of a predetermined size for allowing particulate material up to a predetermined size to pass through the screening module; (c) a plurality of attachment assemblies for removably joining the plurality of screening modules to the support frame; and (d) a plurality of fasteners for connecting the support blocks to the support frame.
