how copper processing plant crush massive quantities of ore

Many copper concentrators all through the planet have knowledgeable troubles associated with capacity. The ability and power use of a SAG milling circuit is directly influenced by the scale of the feed towards the grinding mills along with the strength characteristics in the feed material which, during the lifetime of a mine, can display wide variations. These factors, in turn, affect the quafactory building sand handling washing screening sortingntity of circulating oversize which must be refed to the SAG mill.

Case Study

A Chilean copper mine operates one particular from the lowest grade copper porphyries to become mined in Chile. This, naturally, means how the processing plant ought to crush very massive quantities of ore in the absolute minimum expense.

The operator was experiencingproblems with concentrator capacity, due to the quantity of recirculating load to the SAG mill, using the plant currently operating 24 hours every day, an organized expansion necessary the SAGmill to use at a greater throughput than was feasible with their circuit.

Proposal

After substantial on-site testing, it was proposed a Barmac VSI crusher be installed to decrease the quantity of material being re-circulated for the SAG Mill.

Solution

The SAG mill pebbles are crushed inside a cone crusher in open circuit and also the Barmac is installed in closed circuit having a screen, following the secondary cone, to minimize the size in the feed to the ball mill. This has enabled the main SAG mill to operate in open circuit. The elimination in the recirculating load towards the major has meant a significant boost in capacity.

Other Positive aspects and Advantages

Not only did the business manage to solve their plant capacity troubles using the installation of the Barmac crusher, nevertheless they accomplished it with a relatively low capital expense. Along with this, the Barmac has proved to operate at low put on charges and with high availability, and it has the additional ability to readily absorb any surges in throughput.

The production of oversize from your SAG Mill tends to be very inconsistent and the Barmac copes with throughput variations from as little as 60 tph up to 180 tph.

Conclusion

The Barmac VSI's unique autogenous crushing and grinding action continues to be really effective in crushing the incredibly tough oversize pebbles from your mill, therefore rising the ability in the whole crushing circuit.

Major Benefits For the Copper Mining Industry

There are escalating environmental pressures inhibiting the improvement and exploitation of latest mineral deposits. This, together with all the rising fees of energy generation, has developed a world-wide trend which sees mine and processing plant lives being extended through the adoption of energy effective comminut ion processes in existing milling circuits to provide financial capacity increases and the optimisation of mineral recovery.

The Barmac VSI crusher uses a unique rockon-rock crushing process. This crushing action grinds and mills the feed material to create a fine product without any contamination from put on components. Because the material fed into the Barmac grinds and impacts against itself, the standard wear expense per tonne of material processed is really low.

Barmac Model Chosen:

- Material: Copper Ore

- Feed: -25mm

- Item: -12.5mm

- Rotor Tip Speed: 74 m/s

- Circulating Load: 50 tph

- B9600 Barmac VSI

- 300 kW (400 HP)

- Throughput: 140 tph (full capacity just isn't realised due to inconsisent feed from SAG mill)

Barmac VSI crushers will also be used inside the industrial minerals, mining, recycling and general quarrying industries. An array of materials are processed via Barmac crushers worldwide.
