Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).
Crushers are one of the essential quarrying machines used in foresaid industries which are generally used to reduce the size of large size rocks into small stones, sand dust and gravels.
