SSI - Segmented Cleaning Fingers
Cleaning fingers prevent material from accumulating between cutters or wrapping around the a shredder’s shaft. They also provide extra shaft support in applications which experience shaft flexing. These flat steel plates attach to the side walls of a shredder’s cutting chamber. The semicircular fingers extend between the shredder’s cutters with finger notches fitting closely around the spacer.
SSI offers segmented, or ‘floating,’ cleaning fingers held in place by retaining brackets on each side of the cutting chamber. The segmented design allows easy removal (via the shredder’s endplate area), as well as repositioning should the cutter stack arrangement be modified, or if cutter thicknesses change through rebuilding. Shredders lacking the segmented design often use cleaning fingers connected in a solid comb-like weldment. These units generally require cleaning finger removal via the bottom of the shredder. This is an extremely cumbersome process given the size and weight of the assemblies, especially if discharge chutes or conveyors are in place. These arrangements require the entire assembly to be replaced with even slight cutter thickness changes.
SSI’s individual, segmented design of the fingers allow for much easier maintenance than the traditional, unibody, “comb” arrangement used by other manufacturers. SSI cleaning fingers can be accessed directly and more safely from the top.
