Cone Crushers are commonly used for secondary, tertiary or quaternary crushing. It genius lies in it's durability and simplicity - there are only nine moving parts to these heavy duty machines. This cone crusher is able to pass uncrushable materials that have somehow entered the crushing chamber by opening the crushing cavity hydraulically instead of using springs. The importance of the cone crusher has significantly increased, because of its effectiveness and lower operating costs. It is able to crush hard, medium-hard, and many different types of materials, while providing a reliable and efficient crushing operation.
