Introduction to the Vertical Shaft Impactor
Vertical Shaft Impactor 15
Lid Assembly
The lid assembly consists of the
feed box, feed tubes, lid liners
and inspection doors. The lid
contains the crushing action
and provides a feed entry point.
For access to the complete
crushing chamber, the entire
lid may be lifted after removing
the hold-down wedges. On
models equipped with a Hydra-
Arm, the lid can be raised and
rotated hydraulically. The lid
is equipped with bolt-in alloy
liners.
Feed Box
The feed box collects feed
material and directs it down
the feed tube. The feed box
is designed with a rock shelf
to provide rock on rock wear
protection.
Feed Tube
The feed tube plays a vital role
in the overall performance of
the crusher. The feed tube
directs the feed material
directly into the crushing
chamber. It is important that
proper height adjustment
between the feed tube and
accelerator is maintained for
efcient production.
The feed tubes are reversible
and replaceable for abrasion
resistance and ease of
maintenance.
