ABB is delivering minewide electrical and process control solutions and the most powerful gearless mill drive systems ever made at the world's highest altitude mining project: the 4,700 m Toromocho copper mine in Peru. Toromocho Mountain is one of the world's largest untapped sources of highquality copper. It is also one of the highest.
() motor for a ball mill, to Lafarge Cement in France in 1969. Since then, GMD systems have become larger, more powerful, and are now operating at higher altitudes even above 4,000m where the extreme environmental and boundary conditions challenge the lifetime of a GMD. Under these demanding conditions, only the
The use of VSDs makes it very easy to set the mill speed by just modifying this value on a touchscreen. But this is not only an option for new installations. In installations where SAG and Ball mills have been working for several years at fixed speed, but the speed regulation has been observed to be necessary VSDs can also be integrated very ...
The new tachometer generators are Cface flange or foot mounted designs that require tach adapters. They have a rugged cast iron housing is suited for mill applications and has better electrical shielding. The output signal has very low ripple current.
Applications. ABB tractions motors for electric multiple units. Few or several driven axels ABB provides traction motors for both design concepts. ABB traction motors for light rail vehicles. Every LRV is unique and so should its motors be every motor has its own design. ABB traction motors for locomotives.
The grinding process with one 34' x 20' SAG mill and two 24' x ' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. Copper Mountain has installed on all three mills, the new stateofthe art dual pinion mill drives.
answered. Depending on the mill size and type, the mill can be driven by several configurations of drive systems. The main options are single low speed motors connected to a pinion driving a ring gear, two low speed motors connected to two pinions and driving a ring gear, or a gearless motor mounted directly onto the mill. In addition, a gearbox
