VIBRATING GRIZZLY FEEDERS
Grizzly feeders are used to
separate raw materials into two
fractions to send to the primary
crusher only the largest
elements and to eliminate the
undersize. In quarries, this
operation is to avoid sending to
the crusher material which does
not need to be crushed.
Machine Roll’s Grizzly feeders
are heavy-duty pan feeders with
Grizzly sections added to the
pan surface. They perform both
scalping and feeding in a single
unit and are designed for impact
loading and heavy burdens. When
installed ahead of the primary
crusher it performs coarse
sizing and provides a
controlled, high-capacity flow
of material. It eliminates
crusher overload due to material
surges. It also reduces crusher
wear and maximises crusher
capacity by bypassing material
already at or below desired
size.
The vibratory shafts are
machined eccentrically to
produce a liner motion. The
resulting turning motion of the
material provides high capacity
and scalping action as the
material is turned to expose all
sides to the grizzly openings.
Machine Roll offers our heavy
duty feeders in single or duel
shaft designs.
