The jaw crusher is currently the most widely used type of crusher internationally. It offers advantages such as a high crushing ratio, uniform product granularity, simple structure, and ease of maintenance; it is available in versions for both primary (coarse) and secondary (fine) crushing. The crusher is driven by an electric motor via belts and pulleys; an eccentric shaft causes the swing jaw to move up and down. During the downward stroke, the angle between the fixed jaw and the swing jaw decreases, crushing the material. During the upward stroke, the angle increases, and the swing jaw moves away from the fixed jaw plate—assisted by tie rods and springs—allowing the crushed material to discharge from the bottom of the crushing chamber.
The crushing chamber is deep and free of dead zones, enhancing feed capacity and output;
It offers a high crushing ratio and produces material with uniform granularity;
The shim-based discharge opening adjustment system is reliable, convenient, and offers a wide adjustment range, increasing equipment flexibility;
The lubrication system is safe and reliable, components are easy to replace, and maintenance requirements are minimal;
Simple structure, reliable operation, and low operating costs;
Energy-efficient: a single unit saves 15%–30% in energy consumption;
Wide adjustment range for the discharge opening meets diverse user requirements;
Low noise and minimal dust generation.
