    OPERATING AND DESIGN CONDITIONS
 4.1
    
    General
 The equipment will be installed outdoors and shall be designed to operate 24 hours
per day, 7 days per week, 365 days per year. The Supplier shall identify in his
proposal all special requirements for outdoor operation in a tropical climate.The grinding system will consist of one SAG mill followed by one Ball mill. The SAG
mill will operate in closed circuit with an integral trommel system. Trommel
oversize will discharge to the pebble crusher feed conveyor. Trommel undersize will
report by gravity to a Ball mill cyclone feed

sump.    The Ball mill will operate in closed circuit with a cluster of cyclone classifiers.
Provision will be made for a portion of cyclone underflow to be recycled to the SAG mill
feed if required.The ultimate capacity of the grinding system is 600 dry tph metric, which is the new feed
rate to the SAG mill. This design capacity includes a 92% mechanical availability
allowance.The detail design and construction requirements for the SAG mill components and gearing
are specified in Appendix B and Appendix C.
 4.2
    
    Performance
 The SAG mill receives primary crusher discharge as follows:
 Ore specific gravity
    
    
    2.78Ore dry bulk density, t/m3
    
    
    1.4Ore feed rate, dry t/h
    
    
    600Feed size, 80% passing, mm
    
    
    150Feed size, maximum, mm
    
    
    400Product size, 80% passing, microns
(trommel undersize)
    
    
    1,200Slurry density mill discharge, % solids
    
    
    65
 The mill is estimated to be capable of drawing the 5500 kW at the pinion at 75% of
critical speed with a 12 to 15% or greater ball charge and a total charge of 28%.The mill should be able to operate at the design conditions (10% ball charge, 28% total
charge) in the speed range of 50% to 75% of critical speed over the full wear life of the
liners. For the 75% to 85% speed range the mill should be able to operate at maximum power
but possibly with reduced ball charge.
 4.3
    
    Performance Warranty
 The SAG Mill is mechanically and structurally capable of drawing 5,500 kW.Process Performance:The Supplier warrants the following:That the 28 x 14.5 SAG mill will draw at least 5,200 kW as measured at the motor shaft
with:
 -
    
    Ball charge in the range of 12% to 15% at a total charge of 3 28%-
    
    Pulp density in the range 65 to 75% w/w-
    
    F80 less than or equal to 175 mm-
    
    Mill speed in the range 73 to 77%
 And provided that the following conditions are met:
 
    
    That the milling circuit is operated by experienced personnel
    
    That all auxiliary equipment is selected, installed and operated to suit the circuit requirements.


    
    
    That the milling circuit is fed an ore with a specific
gravity ≥ 2.7
 4.4
    
    General FeaturesThe equipment shall be the Suppliers standard design and of heavy-duty construction
suitable for the operating conditions specified.See Appendix B, Mill Components, and Appendix C, Mill Gearing, for a more detailed
description of design and construction requirements for the mill.The mill pinion shall be direct coupled with an air operated clutch to a variable speed,

    Ball Mill, wet overflow type, to be driven by a
fixed speed 32 pole 4800 kW GE synchronous
motor (motor supplied by LGL), inside diameter
of shell 5490mm, effective grinding chamber
length 9750mm, complete with shell, SG iron
heads with integral trunnions, trunnion bearings,
baseplates, sole plate with provision made for
inching drive attachment, ring gear, pinion and
pinion bearings, gear guards fitted with heating
devices and appropriate cleanout doors, all
integral pipework and trunnion liners. Feed and
discharge bearings to be 2450mm diameter by
800mm wide.2
    
    
    1
    
    
    
    
    Feed chute assembly, to incorporate trunnion
liner removal facilities and interlocks to prevent
mill rotation while chute is attached to the liner
while the liner is still attached to the mill;
mounted on four rail type wheels with four
auxiliary side shift rail wheels which may be
lowered hydraulically using the Purchasers
portable Enerpac pump unit. Sheet metal shrouds
to be fitted over the hydraulic cylinders to protect
against mud splash, etc. To be provided with a
locking device to ensure that carriage cannot
move while mill is turning.3

    Trommel assembly, 2400mm (nom) diameter by
3000mm (nom) parallel length, not inclusive of
the conical transition piece between the trommel
and the trunnion. Panels to be 6mm square
opening snap-in flat rigid polyurethane.
Trommel to include a scats discharge system
(mechanism to be determined). All steel surfaces
subject to abrasive wear to be substantially
rubber lined.4
    
    Lot
    
    
    
    Discharge Trunnion liners to be Skega type with
stud fixing. Transition piece liners between
trunnion and trommel to be Skega rubber
segments with T-Bolt fixing with the nuts
accessible from outside the mill. Rubber spirals
in trommel and trunnion to be knock-in type.5

    Pinion bearings lubrication system to be separate
from the trunnion lubrication system. Filters to
be 20μm paper element of oversize capacity.
Rexroth drawings to be approved by the
Purchaser prior to commencement of
manufacture.

    Trunnion bearings lubrication/lift system to be
identical (save for the gear type rotary flow
dividers capacity) to the SAG mill system. The
spherical seat lift pumps are to be located at the
trunnion housings during mill erection, but the
lubrication module and oil reservoir is to be
designed to facilitate relocation of these pumps
after the mill is commissioned. The lubrication
system is to incorporate cooling and low pressure
filtration to 20μm by paper element filters prior
to entry into the high pressure pump suction
compartment of the oil reservoir. Standby pumps
and filters are included. Drip trays to be
sufficiently sloped and arranged to permit gravity
drainage into collection containers. All Rexroth
drawings must be approved by the Purchaser
prior to commencement of manufacture.7
