XY1500*2000 Jaw Crusher With Non Welded Frame Long Stroke Stone Crusher 1200mm Max Feed

The XY European Version Jaw Crusher is developed by Xinyida Machinery following comprehensive research into crushing mechanisms and successful integration of advanced European and American engineering technologies. Through finite element analysis and dynamic motion simulation, this crusher has been refined through multiple iterations to become a preferred solution for processing hard and abrasive materials. The product is engineered with a clear focus: achieving maximum output while minimizing operating expenses.
When compared with conventional domestic crushers, the XY European Version Jaw Crusher offers distinct advantages in design, construction, reliability, reduction ratio, ease of operation, maintenance simplicity, and installation convenience. These characteristics make it a practical and dependable choice for the local market.

The crusher employs pin-and-bolt connections together with riveting instead of traditional welding. This approach eliminates stress concentration points and significantly improves fatigue strength. The frame maintains its rigidity and integrity over years of continuous operation. The integrated modular design keeps the structure compact while enabling rapid disassembly and assembly of all components. This translates directly into lower costs and less time spent on transportation, site installation, and routine maintenance.

The swing jaw assembly is built around a forged eccentric shaft of heavy-duty specification, paired with large high-quality rolling bearings. The swing jaw body itself is optimized through finite element analysis. A heavy-duty guard plate mounted on the upper portion of the swing jaw protects against impact damage from falling material, shielding both the jaw body and internal bearings. This robust design extends the operational life of the crusher under demanding conditions.

Unlike traditional designs where eccentricity remains uniform, the XY European crusher features eccentricity that increases progressively from top to bottom, reaching its maximum at the discharge opening. A steeper toggle plate angle complements this design, producing a longer linear stroke with each revolution of the eccentric shaft. The resulting aggressive jaw motion, combined with maximum eccentricity at the bottom of the crushing chamber, delivers higher throughput, a larger crushing ratio, and improved product particle shape.

The deep, symmetrical V-type crushing chamber ensures that the actual feed opening width matches the nominal width precisely. Feed opening depth has been repeatedly optimized to allow material to enter without obstruction, maximizing feeding capacity. The nip angle between the swing jaw and fixed jaw liners is determined through rigorous force analysis. A properly designed nip angle guarantees strong biting force, promotes smooth downward material flow, reduces liner wear, and lowers overall operating costs.

An integral cast steel bearing housing fits perfectly with the frame structure. This eliminates the unnecessary radial loads that commonly occur during fastening when using split or combined bearing housings. The result is smoother bearing operation, reduced vibration, and extended bearing service life.

Fixed jaw plates and swing jaw plates are fully interchangeable and reversible. Additionally, the left and right cheek plates are interchangeable with each other. This design maximizes the utilization of every wear component, significantly reduces spare parts inventory requirements, and delivers substantial long-term savings on wear-related replacement costs.

The crusher features a mechanical discharge opening adjustment device incorporating a dedicated gear force-multiplying mechanism combined with double-wedge technology. Compared with traditional shim adjustment methods, operation is simpler, safer, and faster. This design substantially reduces downtime during adjustment procedures, keeping the production line running efficiently.

Q: What materials is this crusher suitable for?
A: The XY European version jaw crusher is specifically designed for hard materials, such as high-hardness rocks and ores. Its deep crushing chamber and strong biting force ensure high efficiency in primary crushing applications.
 
Q: Are the capacity data in the table guaranteed?
A: The capacity data listed are reference values only. Actual throughput may vary significantly depending on material properties (hardness, gradation), feeding method, moisture content, and clay content. For specific applications, please consult Sichuan Xinyida Machinery Co., Ltd. for tailored recommendations.
 
Q: What is the relationship between "Closed Side Setting (CSS)" and product size?
A: CSS refers to the minimum gap at the bottom between the jaw plates. It directly determines the maximum product particle size. A smaller CSS yields finer output but lower capacity, and vice versa. Please refer to the product size table for detailed correlations.
