Cone Crusher Evolution

Edgar B. Symons designs the pillar shaft gyratory crusher in 1907 while working for Smith & Post, the predecessor to Smith Engineering


The Symons Horizontal Disc Crusher In 1911, Mr. Symons develops another crusher, the horizontal disc crusher. crusher. He and his brothers start a new company called, the Symons rot ers o. to eve op an se t s new nvent on. The horizontal disc crusher used centrifugal force and a gyrating acti action on to re eate eatedl dl crus crush h the the ore ore as it asse assed d outw outwar ard d thro throu u h the the chamber.


The Symons Vertical Disc Crusher A later design patented in 1915 became the Symons Vertical Disc Crusher

Gyradis Gyradisc c crushe crusherr developed developed in early 1950’s to operate with multi-layer crushing on a narrow zone o e c am er Mainly used for producing as halt chi s and manufactured sand


The Omnicone™ Crusher The Omnicone was developed in ’ modern crusher with the same crushing action as the Symons cone which would be better suited to the mo e crus ng mar et. The crusher was more compact, better better balanced balanced and had had modern modern hydraulics to provide setting adjustment, tramp release and cavity clearing


The Omnicone™ Crusher

, crusher became popular because it used one bowl and head for all crushing cavities and provided the crushing capacity in a more compact machine than the Symons cone

adjustment, tramp release and clearing meant that the crusher was able to have higher availability and to opera e a e op mum se ng
