SECTION 2 - GENERAL INSTALLATION INFORMATION
MP SERIES CONE CRUSHER TECHNICAL REFERENCE MANUAL
2-29
2.15 Piping Information
Section 10
, describes in detail the proper type of
oil, its temperature and regulation, as well as the
equipment that is used or could be used in the
crusher lubrication system. It should be noted that
the lubricating system for the Crusher is designed
for 8.6 BAR (200 PSI)
maximum
operating
pressure.
Consult piping drawings furnished to show the pipe
and pipe fittings supplied with the Crusher and any
other lubricating equipment. Pipeline layout will
vary to suit local conditions. Two influencing
factors should be considered in the layout of both
feed and drain lines; the pipeline should be as short
and as direct as possible, without dead pockets or
other flow obstructions and the drain line should
have a minimum pitch of 25 mm (1") for every
305 mm (12") of pipe used.
It is necessary that all piping be checked for
internal cleanliness, that all chips and cuttings be
removed to safeguard the oil pump. Take proper
precautions to clean out weld slag and other
contaminants.
2.16 General Assembly and Disassembly
Information
Nordberg MP Cone Crushers are shipped in
subassemblies.
In succeeding sections, detailed instructions will be
given covering the assembly and disassembly of the
various crusher components. Starting with the main
frame, the remaining components are discussed in
their normal assembly sequence.
Before installing any of these crusher parts, check
that the protective coating applied to all machined
surfaces for shipment has been removed and that all
parts are clean and free from grit and dirt,
especially oil passages and pipes.
All machined surfaces and threads that may have
possibly been damaged in shipment must be
restored to the proper condition before assembly.
After cleaning, lightly oil all bearing surfaces and
machined surfaces of mating parts with the
exception of the Bowl, Adjustment Ring, and
Clamping Ring threads which should be treated
with a special thread lubricant (supplied by Metso
Minerals) before applying the special grease with
molybdenum disulfide additive shown in
Section 11
.
Due to the size of the MP800 and MP1000
Crushers, special precautions must be followed
during the removal and installation of certain
components. Be sure to follow all applicable safety
practices regarding lifting equipment including
proper hand signals. Also, make sure that all lifting
equipment and associated devices such as slings,
hooks and hardware are of sufficient capacity to
support the weights involved.
The repair instructions in various sections of this
manual make reference to the lifting instructions
contained in that section. Handle components only
as shown in the illustrations in that section. Do not
use an alternative component handling method
without first consulting Metso Minerals, Inc. (See
Special Tools
for items required for component
handling.)
2.17 General Maintenance Information
When performing any maintenance work on the
Crusher, the following general precautions should
be observed:
•
When removing parts with machined or
bearing surfaces which may rust, they should
be well oiled or covered with a rust preventive,
if they are kept out of the Crusher for any
length or time.
•
Use additional caution when handling any
parts which have bearing surfaces or a
machined surface that has close tolerances.
•
When disassembling any parts with bearing or
machined surfaces, protect these surfaces from
coming in contact with the ground by using
wooden blocking.
•
Bronze liners or bushings should be handled
with extreme care. Excessive ramming or
pounding on this soft material may cause
warping or springing of such parts.
NOTICE
Avoid vertical drop sections in drain line.
