The Copper Mountain Mine has a workforce of 420 employees and is located 20 kilometres south of Princeton. The mine produced 66.2 million pounds of copper in 2013. The 2014 production target is 80 to 90 million pounds of copper, plus gold and silver byproducts. The mine is Copper Mountain Mining's flagship asset.

Typical size ranges would start with run-of-mine coal feeding to the primary sizer at 2000 mm, and reducing to 350 mm. The secondary sizer would receive this coal and discharge at a nominal 125 mm, followed by a tertiary sizer/screen combination to generate a 50 mm topsize preparation plant feed (FL, 2011).

The primary crusher reduces the size of the raw material and prepares it for the secondary crushing stage, while the secondary crusher further reduces the material size and shapes the final product. Both types of crushers are essential in various industries and contribute to the overall efficiency and productivity of the crushing operation.

The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm.

In most applications, the secondary crusher has a primary target of maximizing the reduction ratio and reducing the top size and F80 for the downstream equipment. However, in some …
