Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

Cone Crusher MAINSHAFT. The mainshaft is of high grade forged steel, annealed for stress relief. It is tapered to gauge for head center fit. The bottom of the shaft is fitted with a polished bronze step bearing. The journal for the spider bearing is formed by a sleeve shrunk on the shaft on the 51, 60 and 84-in. crushers.

The degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced. Primary crushing is the first stage of material reduction and can sometimes be …

Secondary Crusher Functions and Features. As the name suggests, secondary crushers come into play after primary crushers in the crushing process. Their primary function is to reduce the size of processed materials further before the final product is obtained. The impact of secondary crushers on the final product cannot be overstated.

A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by:

The first step in choosing a primary crusher takes place at a high level. It's necessary to identify the purpose the crusher will be used for. This purpose is a given that precedes the entire decision-making process. Sometimes, a measure of guidance or experience is needed. The two main components to consider when identifying purpose are feed ...
