Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
The cone crusher is a modified gyratory crusher and accordingly many of the same terms including gape set and throw apply The essential difference is that the shorter spindle of the cone crusher is not suspended as in the gyratory but is supported in a curved universal bearing below the gyratory head or cone Figure Major suppliers of cone crushers include Metso
