Two interacting stacks (26,28) of peripheral overlapping shredding members of disk form are mounted on substantially parallel shafts (30,32) and positioned transversely to the direction of waste material passing through a comminutor casing (10'). The casing opens upstream and downstream side for introducing liquid borne waste to the chamber and for discharging the comminuted waste therefrom after shredding, respectively. The casing is closed off by a pair of imperforate side rails (20'), each side rail (20') is slotted to form a series of inwardly projecting planar fingers (74) having front edges of circular arc form facing the periphery of the rotating cutting element disks (52,54) and having a radius larger than the radius of the disks (52, 54) and being spaced slightly therefrom. The array of fingers (74) extend over the complete height of the stack (26,28) shredding members. This facilitates greater flow of the liquid through the comminution chamber via slots between the fingers (74) carrying fine solids to enhance comminution. |
