When the Symons brothers Invented the cone crusher, they employed the principle wherein the length of the crushing stroke was related to the free fall of material by gravity. The cavity design eccentric head speed and throw of the hydrocodone are equivalent to the Nile Machinery Symons Cone Crushers.
For finer crushing or reduction a Symons cone crusher the norm, which is commonly used for secondary, tertiary, or quaternary crushing. They do this by a different chamber design which is flatter and by operating at about twice the rotational speed of a primary type gyratory crusher. The Symons cone crusher is adjusted by spinning the bowl up or down manually or through hydraulic rams. A series of powerful springs give the necessary tramp protection. Several other manufacturers produce similar types and sizes of crushers but all follow the basic types described.
Versatility in the form of Symons cone crusher having the ability to perform in a wide range of applications without the need for a change in major assemblies was another objective in the design. Ease of maintenance and remote setting capability also were part of the design parameters our market requires.
