Mill Pinion Gears. Our high torque, high precision integral and nonintegral mill pinions are used in SAG, horizontal ball mill and rotary kiln applications across the globe. Supplied as an individual component
the mill gear in inching mode N o_mill is the actual output speed of the mill gear in normal running mode P mill_motor is the actual power of the main drive motor or 2 x main drive motor for dual pinion drives. The power computed above is considered P inch = N o_inch #183; P mill_motor N o_mill
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.
in single and dualpinion configurations. These drives are wellsuited for all type of mills and ball mill applications, and are able to cover the power range up to the mechanical limit of the gearbox or the ring
We provide SAG and AG Mills up to in diameter. Our mills use conventional geared drives for transmitting up to 18,000 kW of power by use of a twin pinion system. Depend on years of proven reliability and productivity. Weve been producing the highest quality SAG and AG Mills
Conventional mining process circuits use both SemiAutogenous Grinding (SAG) and Ball mills. It is very common that the SAG mills are operated with adjusta An electrical impact study between variable speed dual pinion mills and gearless mill drives

drive application is a dualpinion SAG mill driven by two 5,000 kW wound rotor induction motors (WRIM). Two TMdrive10SPRs control motor speed by recovering rotor current and returning the power to the
DUAL PINION MILL DRIVES The SAG and the two ball mills are gear driven and Copper Mountain selected the sophisticated low speed dual pinion mill drives from ABB to drive these mills. Brief History Sophisticated Dual Pinion Mill Drive Technologies About five years ago, ABB was already the market leader for Gearless Mill Drives
ring motor sag mill transport kasprzyk pl. Ring motor sag mill systems eliminate all mechanical components of a conventional mill drive system such as ringgear pinion gearbox coupling as well as motor shaft and bearings thus offering better energy efficiency superior reliability increased process availability and longer lifespan the abb gearless mill drive is the most powerful mill drive
GMDs are used on the larger ball and semiautogenous grinding (SAG) mills, where power transfer through the con ventional gearbox, pinion and girth gear drivetrain becomes the limiting factor.
