Abstract
A rotary disc screen apparatus consisting of a material screening frame having a series of corotating parallel shafts in spaced relation, screen discs mounted on supports on the shafts so the screen discs interleave between adjacent shafts, the screen discs being detachable from the supports for interchangeability with other screen discs of a selected different dimension, and drive assemblies connected to alternate one of the shafts for being able to apply the drive assemblies on adjacent jammed shafts when needed.
Claims1
A rotary disc screen apparatus consisting of a material screening frame having a series of co-rotating and spaced parallel and axially elongated shafts, each of which shaft has thereon an axially spaced apart series of discs which interleave between spaced parallel shafts, and comprising:
- each of said shafts having a series of axially spaced supports thereon encircling the shafts and extending radially outwardly from the shafts;
- a series of discs carried one on each said shaft encircling support, each one of said discs being divided into complementary parts, each complementary part being formed with a recessed surface to abut a shaft support and form a complete disc that encircle the shafts;
- and
- means for securing said complementary parts of each disc in position on a common shaft support with the discs relying upon said supports for establishing the axial spacing of said discs, and wherein said securing means detachably connects said complementary parts of said discs to said supports independently of adjacent discs.
