Get MoreThe overland conveyor for Xstrata Copper's new Antapaccay mine in Peru was reported in this article last year (October 2011, p60). It has just been delivered, with a Siemens gearless drive system. Once commissioned it will convey up to 5,260 t/h of ore over a distance of some 6.5 km from the mine to the processing plant.
Get Moreslope belt conveyor in the Americas. Flywheels are typically used to prevent belt failure in the event of a power or prime mover failure. By mounting the flywheel on the high-speed shaft behind the first-stage pinion, our gear services team was able to reduce the flywheel mass compared to those mounted to the intermediate or low-speed shaft.

Get MoreDownhill Overland Conveyors Generally, belt conveyors only require braking when it takes too long for the system to come to rest (i.e., during a power failure or to prevent "roll-back" of the load when the conveyor is inclined/ declined). In the case of an inclined conveyor, it's normal to use a backstop.
Get MoreOur world-leading belt conveyor system transports crushed copper from underground storage bins to the surface along a 7 km underground tunnel that overcomes a non-insignificant 1 km of vertical elevation change. Once on the surface, ore is then fed onto an overland conveyor that transports it the final 6 km to the distribution silo.
Get Moreoverland reclaim conveyor with a belt speed of approx. 2.6 m/s and an 8 m (26 ft.) lift. The brake is mounted on the high-speed side of the head pulley to dynamically stop the conveyor during an emergency or power failure and function as a parking brake when the conveyor is not in use. A special two-stage HPU and disc were also included.
Get MoreOverland conveyor systems are a cost-effective alternative to trucks for hauling aggregates like sand and gravel over long distances. A single 42" wide conveyor can move as much per hour as a small fleet of trucks. Invest in overland conveyors and see those energy, labor, and maintenance savings go straight to the bottom line.

The system comprises a 300-metre-long sacial conveyor, a 3.4-kilometre-long overland conveyor and a 500-metre-long conveyor feeding the process plant at a design capacity of 5140 tonnes per hour.
Get MoreAs a result, incidents around conveyors are not common. However, due to the energy associated with conveyors, when an incident occurs the consequences are likely to be serious or even catastrophic. There are many hazards that exist around conveyors (for example: dust, noise, falling objects, heavy equipment and rotating / moving parts).
Get MoreConveyor maintenance is a significant daily problem for the mining industry. Conventional methods of detecting bearing failure in conveyor rollers are unreliable, time-consuming and labour intensive.
