4.3.8 Discharge arrangement
Design the discharge arrangement so that material cannot build up beneath
the cone crusher and damage the dust seal ring.
Protect the lubrication and Hydroset lines from falling material.
Concrete foundations or discharge arrangements below the cone crusher
must have an inner diameter that is larger than the cone crusher’s discharge
opening. See
section 3. Technical data .
The volume of the discharge area below the cone crusher must be larger than
the total volume of the process material in the cone crusher and the feed
hopper. See
section 3. Technical data .
If a discharge conveyor stops, the feed arrangement must also stop to allow
the process material to pass out from the crusher.
The discharge arrangement must have an inspection door for cleaning and
inspection. The Hydroset cylinder must be easily accessible.
A ledge or shelf inside the discharge compartment will absorb the impact of
the material falling onto the discharge conveyor.
Chutes should have a slope angle of at least 45° to avoid material build up. In
some cases, the inclination needs to be steeper. Contact Sandvik for further
information.
Crusher mounted on a concrete
foundation or steel supporting structure
with discharge hole in floor. Openings are
blanked off. Crusher mounted on concrete foundation
where the foundation forms two sides of
