Cone Crusher

Cone crushers, as core crushing equipment in the metallurgical and mining industries, primarily provide progressive crushing for various hard materials. Utilizing a unique laminated crushing principle, these crushers crush ores, rocks, and other raw materials in a multi-stage compression process within the annular crushing chamber formed by the rotating and fixed cones, ultimately producing cubic finished products that meet required particle size requirements.

In the metallurgical and mining production process, cone crushers perform key secondary and tertiary crushing. Their unique three-dimensional crushing path efficiently processes highly abrasive materials such as high-hardness iron ore, non-ferrous metal ores, and basalt. Hydraulically adjustable discharge openings and over-trapping protection devices ensure a stable crushing ratio while automatically addressing unexpected situations such as the intrusion of uncrushable materials. The oscillating motion of the rotating cone driven by an eccentric sleeve creates a quasi-elliptical crushing path that subjects the material to a combination of compression, shear, and bending stresses. This multi-directional force distribution is particularly well-suited for processing ores with layered structures, resulting in a higher fines content and a more uniform particle size distribution compared to jaw crushers.
