MP SERIES CONE CRUSHER TECHNICAL REFERENCE MANUAL
• Clean thoroughly and oil all machined parts
before installing them in the Crusher. Do not
replace a bearing surface without coating it
with oil.
• When assembling two mating parts that require
either a press or sliding fit, coat the contacting
surfaces with a light coating of oil. This will
act as a lubricant and prevent rusting in place.
• Head and eccentric bushings are to be stored
vertically, stored in any other position could
cause the bushings to become out of round or
elliptical. Great difficulty could consequently
be encountered when installing them in the
Crusher. In some instances installation would
be impossible.
• All bowl, adjustment ring, clamping ring, head
and locking nut thread surfaces are to be coated
with a special grease with molybdenum
disulfide additive. The specification for this
grease is shown in Section 11 .
• Parts can be damaged by the use of poor
techniques where thermal procedures are
required. The following cautions should be
followed during thermal procedures.
– Whenever possible, heating should be
performed with an immersion oil bath or a
temperature controlled oven.
– Targeted temperatures must not be
exceeded. Damage to parts may occur.
– Cutting torches are unacceptable as
heating elements. The concentrated heat
from a cutting torch results in hot spotting
that may distort parts and adversely affect
induction hardened parts. Localized
heating can also create microscopic stress
cracks.
– Propane or acetylene equipment that is
specifically designed for heating purposes
must be used.
– If flame heating must be used to assemble
gearing, avoid direct flame contact with
the induction hardened areas. Warm the
bore and faces slowly. Let the heat soak to
the outside.
– When heating parts for removal, apply
heat rapidly and evenly. Remove the item
without delay to minimize thermal transfer
to the parent object.
– Do not “quench cool” heated items with
liquids. If rapid cooling is indicated, it
should be limited to motion of ambient air
(fan or compressed air stream).
2.18 Minimum Recommended Spare Parts
List
The following is a list of the minimum spare parts
which should be on hand at all times to ensure a
minimum of down time.
•
bowl liner
• bowl liner bolts
• mantle
• torch ring
• thrust bearing shims (1 set)
• thread lubricant (12 10 oz. cans)
It is to be understood that this list contains only the
minimum complement of spare parts and if the
crusher installation is either in a remote location or
consists of several Crushers, this list should be
expanded. Therefore, consult Metso Minerals for a
suggested list of spare parts for your particular
operation.
Before storing any spare parts, check that the
protective coating applied before shipment is still
intact.
Finally, when replacing any bushings, bearings or
major parts and when the Crusher is being started
for the first time, it is advisable to run the parts in.
Refer to the information described in the paragraph
entitled Initial Start-Up and Break-In Procedure in
Section 11
