Cone Crushers History
The cone crusher was first developed in United States in the 1920’s by Symons Brothers of Milwaukee. Symon Brothers are credited as the first designers and inventors of the spring cone crusher.
The Symons Brothers cone crusher’s biggest advantage was its durability and simplicity (the entire machine had only nine moving parts).
After further years of research and development (R&D), the spring cone crusher became one of the most efficient -and consequently one of the most widely used- crushing machines.
The spring cone crusher design is able to pass uncrushable materials e.g. tramp metal, through the crushing cavity by using springs.
The first hydraulic cone crusher was developed in 1948 and this allowed for the opening of the crushing cavity hydraulically, instead of using springs (mechanical actuation). Both the spring and hydraulic cone crusher designs are still in use today.
Cone crushers are capable of crushing all types of medium to hard mineral rocks and stones. It also offers many advantages over other crusher designs, such as low energy consumption, reliability, high efficiency (compared to other crushers), and a high reduction ratio (feed/input size compared to product/output size).
Despite being present in many industries, it is most commonly used in the construction and mining industries.
Cone crushers are generally found in use for secondary, tertiary, and downstream crushing services, with jaw crushers and gyratory crushers used for primary crushing operations.
In some cases, the Run of Mine (ROM) ore from the mine can be fed to a cone crusher via conveyors and screens, but more often, the feed material will come from upstream primary crusher(s) and cone crushers will be used for downstream crushing stages.
