Two trains of six apron feeders feeders and conveyors will draw ore from below the coarse ore stockpile and feed two parallel wet-grinding lines, each consisting of a 28 MW semi-autogenous grinding (SAG) mill and two 16.5 MW ball mills, all equipped with gearless drives.
• Plenty of surge capacity is provided between the ball mill and the HPGR to sustain constant feed to the ball mills while maintaining the secondary crushing and HPGR circuits. In the case of Boddington, four fine ore bins with a total live capacity of 20,000 tonnes are used, while at Cerro Verde and Sierra
Stones are blasted down from the mountain，and large stones are fed into vibrating feeder by dump trucks. Coarse Crushing. The vibration feeder will feed the stone into the coarse broken evenly by jaw crusher. It is the GradeⅠ crushing; Fine Crushing. the broken stone will be transported to the fine broken stone through the belt conveyor.
For coarse ore, the next alternative is a coarse ore stockpile. Stockpiles of this type are generally 15–25% live and require a tunnel (concrete or Armco) and a number of reclaim feeders to feed the milling circuit. • Multi-stage crushing circuits usually require surge capacity as the availability of each unit process is cumulative.
The vibrating grizzly feeder drops the open pit ore onto the pit ore feeder conveyor which feeds the coarse ore bin feed conveyor. This coarse ore bind feed conveyor receives the crushed product from both the underground mine and the open pit and is designed for a rate of 550 t/h. A fixed magnet is located at the transfer chute between the two
The ore is hoisted from the Reid Shaft to a 1,300 t coarse ore bin. From there, it is transferred to a 250 t coarse ore bin located in the Campbell Mine head frame. The crushing plant consists of two Ross feeders, jaw crusher, standard cone crusher, short head cone crusher, Tyler double deck screen, variable speed short feeder belt, and six
Limestone Processing. The limestone production line designed by Luoyang Dahua perfectly matches the machine character, fully shows its efficacy. This production line has the features of large production capacity, stable operation, uniform granularity, less dust, and the produced particles with good shape. ♦ 1.
As a result, there are two separate coarse ore feed systems. One from the underground workings, which dumps ore into the coarse ore bin from an underground conveyor and a second that incorporates a truck dump, which also feeds ore into the same coarse ore bin.
Oct 15, 2020· The coarse ore will be transported by a belt conveyor to a reversible conveyor, where it can be discharged into two coarse ore bins. Each bin provides a live residence time of 23 hours and a corresponding capacity of 2260t of ore on a wet basis. Ore will be reclaimed from the bins by belt feeders and discharged to the SAG mill feed conveyor.

ROM ore is transported to the primary jaw crusher dump hopper. From the dump hopper, the ore discharges onto a vibrating grizzly feeder that feeds the ore into the primary jaw crusher. The jaw crusher product discharges onto the crusher discharge belt feeder and then onto a transfer conveyor that transports the crushed ore to the coarse ore bin.
