Cone crushers, on the other hand, are more often used in the secondary and tertiary crushing stages. After the jaw crusher has done the primary crushing, the material gets fed into a cone crusher to be made even smaller. Sometimes, several cone crushers might be used one after the other to get the product to the desired size and shape.
