Aggregate processing systems, methods and apparatus

An aggregate processing plant having first and second configurations, the plant comprising:

• a vibratory screen having at least first and second decks;
• a frame comprising a plurality of crossmembers and a plurality of longitudinal members, said frame operably supporting said vibratory screen, said frame having a first set of mounting openings configured to support a wet flume in said first configuration, said frame having a second set of mounting openings different from said first set of mounting openings and configured to support a dry hopper in said second configuration, wherein said wet flume comprises a plurality of sections including a central section a first distal section, and a second distal section, each section comprising a wall, said sections being detachable from said frame in sequence, wherein both first and second sets of mounting openings include openings in at least one of said longitudinal members, wherein at least one of said first and second set of mounting openings includes openings in at least one of said longitudinal members and at least one of said crossmembers, wherein said frame comprises a plurality of structural supports extending below said longitudinal members and said crossmembers, wherein said structural supports are configured to allow removal of each of said central section, said first distal section, and said second distal section from within said structural supports upon detachment from said longitudinal members and said crossmembers.
