A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...

The development of cyanide milling at the end of the nineteenth century required grinding into smaller and more uniform sized particles using Chilean mills, ball mills, and tube mills.
