Cone Crushers | McLanahan

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 ...


In crushers, of either the jaw or the gyratory type, a fragment of rock passes forward intermittently into the space between the jaws. It is arrested when the jaws begin do close upon it; it is crushed while the jaws are closing; it passes in limited amount from the crushing area while the jaws are opening, and is replaced, at the same time, by ...


Some crushers are better adapted to handling certain materials. For example, a jaw crusher can make quick work of viscous materials that contain a lot of moisture. But, viscous materials will cause a cone crusher to jam. Further, how much material the machine can handle differs.


The breakage of rock in a compression crusher can result in a percentage of flat or elongated product. However, most construction specification rock products require a cubical product. The cubicity of the cone crusher product can be improved with the proper circuit design, screen selection and crusher operating parameters.


All rock crushers can be classified as falling into two main groups. Compressive crushers that press the material until it breaks, and impact crushers that use the principle of quick impacts to crush the material. Jaw crushers, gyratory crushers and cone crushers operate according to the compression principle.
