How Does a Cone Crusher Work? Cone crushers are straightforward pieces of equipment which makes it easy to understand It all starts with the material you need to crush which is known as the feed The feed drops into the crushing chamber which is a large circular opening at the top of a cone crusher Inside the crusher a moving part which

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
