High-Quality Jaw Crushers Manufactured to International Standards
Jaw crushers serve as core primary crushing equipment in global mining, quarrying and infrastructure projects. Their overall quality and manufacturing standards directly affect the efficiency, safety and operating cost of the entire production line. With 15 years of professional experience in R&D and production of crushing and screening machinery, Shanghai Dongmeng produces PEW and DC series jaw crushers strictly in accordance with ISO9001, CE and other international standards. Combined with advanced European technology and customized design, our products feature high reliability, high crushing efficiency and low maintenance cost, widely used in ore crushing, aggregate processing and construction waste recycling projects across more than 120 countries worldwide.
Strict International Standard Control & Full-Range Quality Assurance
1. Design Standards: EU-Oriented for Safety and High Efficiency
Our jaw crushers comply with EU machinery safety standards including EN 1009-1 and EN 60204-1. Adopting optimized V-shaped deep crushing cavity with reasonable nip angle, they achieve large crushing ratio and high throughput while effectively avoiding material slipping and blocking.
Key structures are optimized through finite element analysis. Forged heavy-duty eccentric shafts and high-quality self-aligning roller bearings are equipped to ensure excellent fatigue resistance and impact resistance, perfectly suitable for high-intensity crushing of hard rocks such as granite and basalt.
2. Sophisticated Manufacturing Technology with Strict Details
- Integrated Weld-Free Frame: Made of high-strength cast steel and steel plates with integral bearing seats, it avoids welding deformation and extends service life by over 30%.
- Premium Wear-Resistant Parts: Jaw plates are cast from high-manganese steel alloy. Optimized tooth guard plates enlarge effective crushing area for long-term stable processing of hard materials.
- Full-Process Intelligent Inspection: Strict international quality standards are implemented from raw material inspection, CNC precision machining to final assembly and load test. All machines undergo no-load and load running test before delivery to ensure zero fault shipment.
3. Authorized Global Certifications for Smooth Trade
All series jaw crushers are certified by ISO9001 quality management system, CE and SGS. They fully meet EU requirements on safety, environmental protection and electrical protection, and can be directly sold and used in European Union, Southeast Asia, Africa and other global markets without trade barriers.
Core Structural Innovations Adaptable to Complex Global Working Conditions
1. Large Deep Feeding Cavity for Higher Processing Capacity
Feeding sizes range from 125mm to 1000mm with maximum input size up to 1000mm and hourly output from 180 tons to 750 tons, ideal for large-scale quarry primary crushing and construction waste treatment.
Deep cavity design and reasonable rotating speed improve material passing capacity by 20%, delivering uniform finished products with low flaky particle content.
2. Hydraulic Discharge Opening Adjustment for Time-Saving Operation
Equipped with hydraulic wedge adjustment device replacing traditional gasket adjustment, users can adjust discharge size from 10mm to 300mm within 10 minutes. Automatic pressure relief protection can avoid damage caused by uncrushable materials, greatly improving overall operation efficiency.
3. Integrated Drive & Labyrinth Sealing for Stable Long-Term Operation
Integrated motor base reduces belt loss effectively. Labyrinth sealing and centralized lubrication system prevent internal bearing pollution, prolonging service life and ensuring stable operation in dusty and humid harsh environments.
4. Dual Application for Stationary and Mobile Projects
- Stationary Type (PEW/DC Series): Perfect for large-scale mines and aggregate production lines with stable output and easy maintenance.
- Mobile Jaw Crushing Plant (Crawler / Wheel Type): Integrated crushing, screening and conveying functions with self-driving design. No foundation needed, suitable for mountain areas, remote construction sites and temporary projects.
Wide Global Application & Strong Material Compatibility
With internationally recognized reliable quality, Shanghai Dongmeng jaw crushers are applicable to various working conditions and materials worldwide:
- Hard Rock Crushing: Granite, basalt, diabase for mining exploitation and high-grade aggregate production.
- Medium & Soft Materials: Limestone, sandstone and concrete blocks for road infrastructure and construction waste recycling.
- Industrial Use: Coarse crushing of bulk materials in metallurgy, building materials and refractory industries.
