Ring Roll Crushers
Ring Roll Crushers are Crushers that are excellent machine for medium and fine crushing of metal chips & turnings.
Multiple hammer rings held by rotating arms fixed to high speed rotor shaft crush (by impact) incoming metal turnings & metal chips against a manganese breaker plate and grate bars located in the bottom of the crushing chamber.
Product size is controlled by the selection of the grate bar opening The crusher has anti-jamming features rejecting solid objects.
Typical Design
The crusher is the heart of any chip salvage system, and the Ring Roll Crusher is designed to quickly and economically reduce carbon and alloy steel, aluminum, brass and bronze turnings to shoveling chips.
The rotor is assembled on a heavy heat-treated alloy shaft which revolves in heavy-duty anti-friction bearing enclosed in dust-tight steel pillow blocks.
