The
AMERICAN WSR-22 Reversible Hammermill is used in high abrasion
applications since it reduces primarily by impact.
These machines are designed for secondary and third stage
crushing. Reversibility provides up to double the life
for hammers and impact blocks. High feed drop designed
for more wear savings on hammer faces. These machines are
available in designs for open circuit or completely closed
circuit systems.
Standard
Features:
Hammers
and impact plates are manganese steel castings. Impact
plates are reversible and interchangeable. Machine
is split horizontally at the centerline and upper housing is split
vertically on both sides of the centerline so as to open either
upper quadrant for quick and easy access to the liner plates or
hammers. Each
of these housings are hinged at the horizontal centerline. Bearings
have a B-10 life far in excess of 40,000 hours, and they are
spherical roller bearings. Rotor
shaft is a forged alloy steel, heat-treated for this high impact
and abrasion application. Breaker
plates are sectionalized and reversible, as mentioned above, and
the high strength bolts are hard faced and recessed below the wear
surface to ensure maximum liner life. Bearing
pedestals are machined for proper mounting of the pillow blocks. Impact
plates are externally adjustable to compensate for wear.
