Screening system for screening or diverting particulate material

A method of producing a system for screening or diverting particulate material, comprising:

• providing a plurality of posts which removably and interlockingly support a reinforcing support frame and a module for screening or diverting particulate material;
• providing a reinforcing support frame;
• providing a module comprising either a screening member having an array of sieve apertures of a predetermined size defined therein for allowing particulate material up to the predetermined size to pass through the module or a diverting member for redirecting the flow path of the said particulate material;
• and
• interlockingly and detachably mounting said reinforcing support frame onto said posts and said screening module onto the structural support frame, said non-reinforced screening module being disposed over at least a portion of at least one of the posts, and the screening module being positioned on the frame, so that particulate material passing through the screening module passes through the frame.
