500 X 750mm Jaw Stone Crusher Machine 55kw Jaw Crusher For Mining

The XY European version jaw crusher is developed by Xinyida based on in-depth research into crushing mechanisms, integrating advanced European and American technologies. It adopts finite element analysis and dynamic analysis for motion simulation, and has been repeatedly upgraded and optimized, making it the preferred crusher for hard materials.

This product is designed to achieve maximum output with the lowest operating cost. Compared with similar domestic models, it features advanced design, robust structure, high operating rate, high output, large crushing ratio, easy operation and maintenance, and convenient installation. These technical and performance advantages make it more suitable for the domestic market.

The XY European version Jaw Crusher features an advanced design with pin-and-bolt connections and riveting, which eliminates stress concentration and greatly improves fatigue strength for greater sturdiness and durability. Meanwhile, the integrated modular design ensures a compact structure, allowing quick disassembly and assembly of all components, minimizing time and cost for transportation, installation and maintenance.

The swing jaw assembly consists of a heavy-duty forged eccentric shaft, large-size high-quality heavy-duty rolling bearings, and a swing jaw body optimized by finite element analysis. A heavy-duty guard plate is installed on the upper part of the swing jaw to prevent damage to the jaw body and internal bearings caused by material impact.

The eccentricity gradually increases from top to bottom, reaching the maximum at the bottom. Combined with a steeper toggle plate angle, this achieves a longer linear stroke per revolution of the eccentric shaft. The aggressive jaw motion and long eccentricity at the bottom of the crushing chamber deliver higher capacity, larger crushing ratio and better product gradation.

The deep symmetrical V-type crushing chamber ensures the actual feed opening width matches the nominal feed width. The repeatedly optimized feed opening depth allows material to enter unobstructedly for optimal feeding capacity. The nip angle between the swing jaw and fixed jaw liners is determined via force analysis; a properly designed nip angle guarantees strong biting force, smooth material downward flow, reduced jaw liner wear and lower costs.

The integral cast steel bearing housing ensures perfect fitting with the frame, avoiding unnecessary radial loads on bearings during fastening that occur with combined bearing housings, resulting in smoother bearing operation.

Fixed and swing jaw plates are interchangeable and reversible; left and right side cheek plates are also interchangeable, maximizing component utilization, reducing spare parts inventory and saving substantial long-term wear costs.

It adopts a mechanical discharge opening adjustment device featuring a dedicated gear force-multiplying structure combined with double-wedge adjustment. Compared with shim adjustment, operation is simpler, safer and faster, reducing downtime.
