High-efficiency PEW250×1000 European-style jaw crusher delivers outstanding performance Advantages

Modular Frame

This equipment features an innovative non-welded, disassemblable frame design. In traditional equipment, frames typically employ welding processes. While this method ensures structural integrity, it poses significant challenges in complex underground environments: localized damage makes repairs and replacements extremely difficult, and transportation becomes highly inconvenient. In contrast, this equipment ingeniously connects its side panels and front wall panel via cylindrical pins. This connection method not only simplifies installation, significantly reducing underground setup time and improving efficiency, but also allows the frame to be disassembled into multiple sections for transportation. This facilitates handling and loading, effectively lowering transportation costs and risks. Additionally, the cylindrical pin connection enhances structural reliability. During operation, it better withstands external forces and vibrations, ensuring stable equipment performance.

V-Shaped Deep Cavity Structure

The equipment's unique V-shaped deep cavity structure is key to its enhanced crushing efficiency. The movable jaw plate rises 80–250 mm above the fixed jaw, forming a stepped interlocking structure. During crushing, materials entering the chamber are progressively compressed and broken along the V-shaped deep cavity. This stepped interlocking mechanism ensures materials receive more uniform and thorough crushing forces, substantially boosting crushing efficiency—a 30% improvement over traditional designs. Simultaneously, this design effectively minimizes material blockage, ensuring continuous and stable equipment operation.

High-Efficiency Crushing Capability

This equipment possesses formidable high-efficiency crushing capabilities, effortlessly processing hard rock with compressive strengths ≤280MPa, such as basalt and granite. These hard rocks are characterized by high hardness and toughness, often rendering traditional crushing equipment inefficient and prone to damage when processing them. Through its unique structural design and advanced crushing technology, this equipment achieves high production capacity—reaching 10–40 t/h—while maintaining crushing quality. This makes it highly applicable in mining operations, construction aggregate processing, and other fields.

Low Maintenance Costs

To reduce maintenance expenses, the equipment incorporates labyrinth seals and a centralized lubrication system. The labyrinth seals effectively prevent dust and impurities from entering bearings, minimizing wear and corrosion while extending bearing lifespan. The centralized lubrication system automatically and uniformly supplies lubricant to all critical points, eliminating equipment failures caused by insufficient or uneven lubrication. Simultaneously, the wear resistance of the liner plates has been significantly enhanced. Compared to traditional equipment, the wear resistance of the liner plates has doubled, reducing the frequency of liner plate replacements and further lowering equipment maintenance costs.

Reduced Energy Consumption

In today's era of increasingly tight energy resources, reducing equipment energy consumption is a key pathway to improving corporate economic efficiency. This equipment incorporates advanced energy-saving technology. Driven by a 37kW motor, its energy consumption is reduced by 20% compared to traditional models. This not only lowers electricity costs for enterprises but also aligns with national energy conservation and emission reduction policies, delivering significant social and environmental benefits.

Lower Overall Costs

Compared to cone crusher combination solutions, this equipment offers lower overall costs during long-term operation. Cone crusher combinations typically require multiple units working in tandem, entailing high equipment acquisition costs, large footprints, and elevated maintenance expenses. This integrated unit, however, combines multiple functions into one compact design. Its lower purchase price, smaller footprint, and combination of low maintenance costs with high production capacity result in long-term operational costs 40% lower than cone crusher combinations, delivering substantial savings for enterprises.

High-efficiency PEW250×1000 European-style jaw crusher delivers outstanding performance Works Principle

As the movable jaw rises driven by the eccentric shaft, the angle between the toggle and the movable jaw gradually increases. The toggle supports and transmits the force of the movable jaw's motion. With the increasing angle, the toggle pushes the movable jaw plate closer to the fixed jaw plate. At this point, material is fed into the crusher's V-shaped deep cavity, measuring 250×1000mm. Its unique V-shaped structure enables optimal material accumulation and flow within the cavity.
As the movable jaw plate approaches the fixed jaw plate, the material undergoes dual compression from both plates. Simultaneously, since both the moving and fixed jaw surfaces are equipped with toothed plates, the interaction between these plates produces a grinding effect on the material. This combined force of compression and grinding rapidly crushes the material within the crushing chamber, reducing large chunks into smaller particles.
When the movable jaw descends driven by the eccentric shaft, the angle between the toggle and the movable jaw gradually decreases. At this point, the spring tie rod comes into play, utilizing its elastic force to rapidly return the movable jaw to its original position, gradually increasing the distance between the movable jaw plate and the fixed jaw plate. During the downward and return motion of the movable jaw, the crushed material is discharged from the crusher through the discharge opening under the force of gravity.
The discharge opening size of this crusher can be adjusted within a range of 25-60mm. This adjustability enables the equipment to produce products of different particle sizes according to varying production requirements. Moreover, adjusting the discharge opening is extremely convenient. Through the hydraulic wedge system, particle size adjustments can be completed within 5 minutes, significantly enhancing production flexibility and efficiency.
