Cone Crushers. 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.
Some plants use multiple crushers to reduce the size of their raw materials. Not all crushers can handle large pieces, so a heavy-duty crusher is the first part of the material handling circuit. Jaw crushers can handle really large pieces. They're used to break those large pieces into something more manageable for the smaller crushers.
