The gearless drive design was not applied to the mills in the mineral industry until 1981 when the thenworlds largest ball mill, m diameter and m long driven by a MW motor, was installed at Sydvaranger in Norway (Meintrup and Kleiner, 1982).
A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor, gearbox and both pinion bearings. The recommendations for repairs was close to
MW). It has been the industry standard for SAG mills above 13 MW capacity. However, pinion systems to 8 MW per pinion and dual motor systems with quadruple pinions extend the range of gear driven mills to a theoretical limit of 32 MW. The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia.
Large girth gears are installed around the cylinder to rotate the horizontal ball mill cylinders. A pinion connects these directly to the industrial gear unit. SEWEURODRIVE does not just provide industrial gear units, we provide the complete drive package with specially segmented girth gears.
Ball mills and rotary kilns are most challenging applications that demand a big deal from the drive system. High performance and reliability are very important. When it comes to milling of iron ore, limestone and clinker large axial and radial forces occur. Singlepinion drives must be able to withstand the acting forces permanently.
SAG mill, ball mill, ring gear, dual pinion, drive systems, variable speed INTRODUCTION The project is located 15 km southwest of Princeton, British Columbia (BC), an established mining town. The initial exploration at Copper Mountain dates back to 1884. In 1923, Granby
Such ball mills are used for grinding and crushing mining ore within a large rotating _2: WEG successfully tested a dualpinion ball mill drive in its inhouse laboratory. Part of this project was also the installation of a bypass on panels.
We provide optimized mill drive solutions for all types of ringgeared mills: low and high speed, single and dual pinion, with and without a gearbox all designed
large gear drives Systematic lubrication with Fig. 1: Tube mill with girth gear drive Fig. 3: Possible arrangement of drive elements in single and doublepinion drives. 5 General The gear drives used in tube mills and rotary kilns are usually very sturdy in design and operate at low speeds.

Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages. Motors considered are
of the inching reducer drive can be added to reflect efficiency losses. P inch = P inch #183;(1 + (stage #183; )) where stage is the number of reductions between the inching drive motor and the main drive input shaft (or mill pinion if direct driven) Round up P inch to the next standard motor power. This standard motor power becomes the incher
Autogenous mills are the largest in diameter since the feed grinds itself. A semiautogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller. Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Largediameter mills allow for use of gear ratios
