This curve shows approximately 29 percent of minus 3/4″ in the material as it comes from the crusher, or 29 tons of fines in each 100 tons of crusher output. But, for the circulating load, we are only interested in that fraction of the crusher output which will pass the 3/4″ screen, which is 85 tons.

Crusher fines are small particles of crushed rock, ranging in size from dust to 3/8", generally leftover from rock crushing operations. There are typically two types of rock deposits that crusher fines are produced from: a hard rock quarry or a sand and gravel quarry. Each has various characteristics that affect both appearance and function.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen.

As with jaw crushers, these machines are compression crushers that use a stationary and moving piece of steel to break up the material. Cone crushers use a rotating head to crush the rock within a steel bowl. After initially being broken down in this manner, the material will travel through a narrow opening at the bottom of the bowl to achieve a finer grain size.
