Ball Mill GEAR GUARD. A plate steel gear guard is furnished with the mill for safety in operation and to protect the gear and pinion from dirt or grit. As soon as the gear and pinion have been cleaned and coated with the proper lubricant, the gear guard should be assembled and set on its foundation. DISCHARGE HOUSING "Doghouse"
The gearless mill drive is covering the upper power range of the mills. The torque is transmitted to the mill directly through the magnetic field in the air gap of the motor, eliminating the gear reducer, the ring-gear and the mechanical related issues …
SAG Mill vs Ball Mill. Ball Motion inside a SAG Mill. ... MILL RING GEAR. Ring gears are often supplied with spur gears. They are always split in 2 or 4 pieces in order to facilitate the assembly. Furthermore, they are symmetrical and can be turned round in order to make use of both tooth flanks. The material is cast steel or nodular iron.
SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. ... The open trunnion bearings are sealed with a ...
Ball mill and sag mill girth gear, trunnion head. Both the ball mill and the sag mill can process non-metals, ferrous metals, non-ferrous metals, rare metals, etc., and are divided into dry and wet types to meet the needs of various materials. The structure of the ball mill and sag mill is similar.
The complete SAG Mill package manufacturered and supplied by Outotec includes: Mill shell fabricated in 8x90° segments; Mill heads cast in 4x90° segments with demountable trunnions; Ductile ring gear and carbonized pinion shaft; Pinion shaft assembly equipment; Erection cradles; Bracket, coupling and guard
For smaller gears a flexible probe like a piece of thick vinyl can conform to any gear shape required. In most cases removal of lubricant isn't required. Any cracking is immediately detected and sized. We can complete the inspection on your ball mill, rod mill or SAG mill in one shift and get it back into production fast.

Repairing Gears. Deadlines and budgets do not always allow for "first class" gearbox rebuilds. The challenge for rebuild shops is to find the fastest and most economical way to return equipment to full functionality. Last time we reviewed housing repairs; in this installment we will cover gears. Some gears just cannot be properly repaired.
By eliminating bolt-on mechanical components such as ring-gears, pinions, couplings and gearboxes, GMDs offer ore producers unrivalled availability, efficiency and durability, while reducing operating expenditure. Both ring-geared mill drives and GMDs can be employed to drive autogenous, semi-autogenous (SAG) and/or ball mills.
