Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations of cone crusher are used, standard and short head. The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangements of the mantle and the cone at the discharge end of the cone crusher. The size distribution of the products tends to be determined in such a manner that no particle can fall through during a single open side passage through the crusher. The machine is adjusted by screwing the bowl of the crusher up or down. It is general practice to install ahead of the secondary crusher, a vibratory type of screen in order to screen out all the material that has already been crushed fine enough by the primary crusher, there by increasing the capacity of the secondary crusher.
Cone type flanged strainers are available in stainless steel or carbon steel. Cone has raised inner lip design which prevents it from blowing out and down pipeline. All carbon steel cone strainers and orifice plates are identified with blue flange.
