Electrical Equipment wanted to purchase for 2 new ball mills and new concentrator plant construction Background:Our client is purchasing 2 x 18 foot in diameter by 30 feet long ball mills with an installed power of 5.5 MW for a new mineral project Our client is in the process of designing and building a concentrator plant to process ROM material that has a bond work index of 14) which will be commissioned at the end of 2009.They have a conventional MF1 circuit and plan to treat the Run of Mine material through crushers to produce a nominal minus 100mm material,which will then be fed into two primary ball mills with an installed power of 5.5MW each.These mills will reduce the ore to minus 75 microns.The headfeed to the crushers will be 500 tons per hour and then to each primary mill,250 tons per hour.WANTED to BUY Mill Motors - Medium Voltage 11kV 3 phase squirrel cage and wound rotor Performance Motor shall be m a nufactured for continuous running duty type S1 with a rating class for continuous duty.The rated output of the motor shall be given in the data sheet.The number of poles and synchronous speed shall be given in the data sheet.The motor shall be capable of carrying 150% of rated current for 2 minutes when running at the rated voltage and frequency.The motor breakdown or maximum torque developed between standstill and rated speed shall not be less than 1,6 times the rated torque with rated voltage and rated frequency applied.The motor shall be capable of withstanding an excess torque of 1,6 times the rated torque for a period of 15 seconds without stalling or an abrupt change in speed.Full load slip shall not exceed 2% of the rated synchronous speed.The motor is to be suitable for use on either a solidly earthed or resistive earthed system.A resistive earthed system will be limited to 350 Amp for 30 seconds through a neutral earthing compensator resistor.The mo to r insulation systems shall have a thermal classification of Class F in accordance with the requirements of SABS IEC 60085 and be suitable for operating at any altitude up to 1650 metres above sea level with an ambient air temperature of 40C.The temperature rise shall not exceed Class B minus 10C (stator temperature 70K rise by resistance) when tested at nominal voltage,frequency and rating in accordance with SABS IEC 60034-2 and SABS IEC 60034-2A at an ambient temperature of 40C and corrected for 1650 masl.Switchgear 11000v Single bus-bar 11000v 25kA 95kV BIL metalclad withdrawable modular switchgear.Bus-bar rating 2000A Incomers 2000A Bus-section panel with joggle chamber to be equipped with Fire-wall bus-trunking 1400mm long either side of panel.2000A.25kA 95kA BIL Feeder panels 800A 25kA 95kA BIL PFC feeder panel 25kA 95kA BIL All protection relays to be of the electronic pattern.
