MP SERIES CONE CRUSHER TECHNICAL REFERENCE MANUAL
all hydraulic components have been
thoroughly coated with rust preventive.
When the Crusher is put back into service,
drain the oil from the hydraulic tank and
refill with the oil specified for the operation
of your crusher.
9. Brush or spray a light-bodied petroleum
solvent containing a substantial amount of a
polar rust preventive additive having strong
attraction for metal surfaces, on the bowl,
adjustment ring and clamping ring threads.
The additive should have excellent ability to
wet metal surfaces in the presence of water;
as a result it strongly resists displacement
from the surface by water. The solvent
should evaporate quickly and leave a thin,
transparent, greasy film. The material
should be suitable for light and moderate
service, for example, protected outdoor
storage. It should be applied at plant
operating temperature by any convenient
means (brushing, rolling or spraying) and
the film need not be removed when the
Crusher is placed in operation.
Then cover the threads with a liberal amount
of lithium based grease NLGI No. 1
containing a minimum of 3% molybdenum
disulfide.
10. Then reinstall the bowl assembly into the
Crusher and cover the entire adjustment cap
and hopper with a sheet of 8 mil. black
polyethylene to prevent water from seeping
into the Crusher and corroding the bowl and
adjustment ring threads. This sheeting is
available in 6.1M (20') by 30.5M (100')
rolls. Black is recommended, as transparent
sheeting will deteriorate four times faster
than black. Use bracing under the sheeting
to ensure that the sheeting does not sag and
that any water falling on top of the sheeting
will be shed. The end of the countershaft
box and countershaft should also be
covered. Steel strapping or banding is an
ideal method of holding the polyethylene
sheeting in place.
11. Reconnect the oil inlet and drain lines. The
oil adhering to the metal surfaces is all that
is needed for proper rust protection.
2.21 Storage of a Crusher
Where it is necessary that the Crusher be shipped or
stored dismantled, the various subassemblies must
be protected more thoroughly, as the procedures
described in Protecting the Crusher Against Rust
Corrosion
earlier in this section are for metal
surfaces that are not directly exposed to the
elements; sun, wind, rain, snow, etc.
The following additional protective measures are
recommended in those instances where a Crusher
must be shipped or stored dismantled and the
various subassemblies exposed to the elements.
The following is Metso Minerals recommendations
for preparation for storage (up to one year) of a
crusher.
The crusher must be disassembled as described
below and all unpainted surfaces and small holes
must be coated with at least 4 mils (0.10 mm
[0.004 inches]) (2 coats) of CRC Industries SP 400
(corrosion inhibitor) or equivalent. For applications
in wet or very humid conditions, CRC 3-36 should
be applied first for complete moisture
displacement. Allow CRC 3-36 to dry 2 to 4 hours
before applying SP 400. Allow SP 400 coating to
dry completely prior to crating or covering
components. All crated components must be stored
indoors or in a container of some sort where there
will be no condensation or collection of water on
surfaces or floor.
If the Crusher is fully assembled it must first be
disassembled into its major assemblies. All
components are to be stored indoors except for the
main frame, adjustment and clamp ring assembly,
head assembly and bowl and hopper assembly.
If the Crusher is to be stored upon receipt of
shipment, it may already be partially disassembled
and many components may already be in crates.
NOTICE
For those parts stored outdoors
unprotected, exposed to the elements, the
following recommendations should provide
up to 12 months of protection against rust
corrosion for machined surfaces. For those
parts stored indoors, the following
recommendations should provide up to 24
months of protection against rust corrosion
for machined surfaces.
