Sanland Equipment Elevates Peru Copper Ore Process to 6,000 TPH+
One of the biggest of Shenyang Sanland Mining Equipment Manufacture Co., Ltd. (Sanland) projects worldwide is a copper ore plant in Peru, which processes around 6,000 tonnes per hour. The size of this plant is such that the use of Sanland's equipment places the mining company at a very high end globally for comminution duty which is typically linked with the top copper producers around the globe.
Sanland's Equipment at Sanland Crushing Capacity of 6,000+
At throughputs of more than 6,000 TPH, a primary crushing plant is not usually the bottleneck but the key deciding factor which makes the whole concentrate factory work at design capacity.
Copper ore presents comminution challenges unique to it, including:
Variable feed hardness - ore bodies often go beyond multiple lithologies that have very different work indices
High abrasion - the gangue mineralogy can make copper ores to have abrasion indices comparable to that of quartz sandstone
Large ROM feed sizes - the primary crusher must handle blast-fragmented feed from which very large blocks of about one metre across can be included
Critical product gradation control - SAG mill performance downstream highly relies on, to a great extent, the top size and gradation of the crushed product
Peru
Peru is consistently ranked among the top 3 in terms of global copper production levels with most of the operations centered at the different segments of Andes ranges and along the Southern Peru copper belt.
Operations with tonnages as large as Sanland Equipment handles at 6,000 TPH are typical of massive open-pit copper deposits that go into the mainline concentrators at mining sites.
Capacity Requirements for Engineering of 6,000+ TPH
When a plant throughput surpasses the 6,000 TPH level the primary crushing would mostly be carried out by a gyratory crusher or by an exceptionally large jaw crusher. Sanland provides SG Series gyratory crushers of the American Technology branch which were designed exactly to be used in primary crushing when very large feed is to be handled.
Secondary crushing and also tertiary crushing after primary crushing is carried out by the cone crushers whose Sanland portfolio alone for the American Technology has 4 series of cone crushers:
SS- Standard andShort-head variants for general secondary and tertiary duty crushing,
SG- Heavy duty, high productivity design with optimal wear parts,
SM - Maximum power class where none of the catalog claims of crushers other than SM series is able to match the SM series'power
SH - High energy, large-reduction-ratio crusher that is able to produce finer products with less crushing stages
Why High-Capacity Crushing Matters for Copper Recovery
In a typical copper concentrator, every unit of additional crushing efficiency translates directly into mill throughput and ultimately into copper-in-concentrate output. Two specific factors drive this:
Top-size control—Tighter top-size control in the crushed product reduces the SAG mill's grinding work and increases the mill's effective throughput by 5 to 15% in many cases.
Inter-particle crushing in cones—Modern cone crusher cavity designs (a focus area of Sanland's SH and SG series) increase inter-particle crushing within the cavity, producing more consistent gradation and reducing the load on downstream grinding.
For a 6,000+ TPH operation, even a few-percent gain in mill throughput corresponds to thousands of additional tonnes of ore processed per day, with proportional revenue impact at metal-market prices.
The Edge from Sanland Automation
It is mentioned in the company's catalog that two automation systems are very suitable for high capacity mines like this:
IC2000 - the automating of crushing by the Impact Crushers of Sanland
Sanland Automation - platform for managing the crushing operations by Cone Crushers that are equipped to automatically change the setting of the closeside so that the crushed material remains at a desired size when the liners get worn down
High-capacity plants have these automation components that really come into play when it comes to production losses from unplanned downtime and thus they are most effective. A feature that Sanland offers with the SH Series Crusher is that its tramp releasing cylinders act like springs and so it allows foreign metals that cause the machines to stop functioning to pass through without the risk of getting stuck or damaging the equipment which is the case of the designs of lesser robustness.
Copper Ore Crushing Operations in Peru As Models for Very Large Mining Projects
Peru Copper mining operation by Sanland which is one of the largest Sanland crushing units with a throughput capacity of more than 6000 tonnes per hour (TPH), would be a very useful reference point for Sanland to use in a bid to persuade other big mining operators to use Sanland equipment for their large scale projects.
The case studies of Sanland include a granite installation in Norway that could process 200 tonnes per hour which was just the lower limit to its 20,000 tonnes capacity installation at the very large Chile gold mining operation. It clearly demonstrates the breadth of Sanland's technical offering with the one manufacturer's equipment being able to address a huge range of operations from small installations to the largest in the industry.
