the so-called power at pinion, which is slightly lower than the gross power and relates to the power as measured at the shaft which drives the pinion gear in a gear-and-pinion drive. Apart from in pilot-scale mills, the power at pinion is never directly measured in full scale operating mills but is Ball Mill Pinion Vibration Analysis Machinery. I have an issue with a gear drive on a ball mill 2XGM is rising and i have sidebands at 107cpm and I dont know why they are at 107 not relevant to any turning speeds ect I checked the root clearance a week ago and the inboard is about a 066 smaller than the outboard The pinion is 24 long and has 24 teeth It is obvious i have there is obvious ... Jul 19, 1999 This invention relates to a drive pinion for a rim gear/pinion drive of rotary drums, such as used in tube mills, wherein the drive pinion meshes with a rim gear on the drum. BACKGROUND OF THE INVENTION. In European Patent EP 0 175 109 B1, one or two drive pinions mesh with a T-section ring gear rigidly secured to the outside diameter of a drum.

Europe Set Default Edition Clear Default Edition 6,5 MW appears to be the upper limit on a single pinion drive and 13 MW on a dual pinion drive is a 22MW unit on a Mill load sharing Maintains equal torques on dual pinion mills throughout the whole speed range. Controlled rollback Prevents backlash and reduces downtime. Mill power ride through Keeps the mill operating even under voltage dips. Over-duty cycle Avoids unexpected downtime if the mill Firstly, there was a serious flaw in the power configuration of the SAG mill and ball mill (both rated at 6000 kW with a single pinion drive). The capacity of the SAG mill was not fully utilized, as the actual operating power draw was only 3358 kW. This meant it was only operating at 56% of its maximum power, providing large room for improvement.

Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive. SAG Mill shells, Ball/Rod for Mill shells, Ball Mill head in halves, SAG Mill heads Girth gears, Pinions, Trunnions, Bearings, Lubrication Units Millrex dual-pinion self-aligning (2,3 4 stages) and Ermill single-pinion self-aligning compact lateral drives Ermaster single, multi-stage and inching drive brake system parallel-shaft reducers drive application is a dual-pinion SAG mill driven by two 5,000 kW wound rotor induction motors (WRIM). Two TMdrive-10SPRs control motor speed by recovering rotor current and returning the power to the utility supply. Configured in a twin motor arrangement, the motors share load in the tandem mill.

Apr 18, 2018 If the mill requires approximately 6000 horsepower or less, it is possible to drive it with a single pinion. To date, however, economics has dictated that most mills over 3500 horsepower be driven with two pinions, using wound rotor motors driving thru speed reducers. These mills are typically powered using electricity and depending on the required power have different configurations such as central drive, single pinion, dual pinion and gearless mechanical set-up. AG and SAG mills are extensively used in the mining industry for extracting minerals such as metals, oil shale, limestone, rock salt, coal ... how to set backlash ball mills.
