Zhongyu Dingli's DLEV series Durable Jaw Crusher is the primary crushing core for mining and aggregate lines, handling ores and rocks up to 300MPa. Low energy consumption, high stability, and simple structure make it ideal for heavy-duty primary crushing across mining, construction, and mineral processing.

Design Highlights
Applications: iron ore, bluestone, limestone processing; construction aggregate; road and railway; water conservancy; chemical industry
Step 1 — Feed Preparation Raw material is loaded into a heavy-duty vibrating grizzly feeder, which pre-screens fines and delivers oversize rock to the jaw crusher inlet at a controlled feed rate. Uniform feeding prevents overload and maximizes V-shaped cavity crushing efficiency.
Step 2 — Primary Jaw Crushing The motor drives the moving jaw to reciprocate via V-belt. Ore fed into the V-shaped cavity is crushed through combined extrusion, friction, and bending as the moving jaw swings. The hydraulic double wedge adjustment device enables precise discharge setting control without stopping production.
Step 3 — Product Discharge When the moving jaw moves away from the fixed jaw plate, crushed material discharges through the adjusted opening. The optimized crushing structure and higher rotation speed ensure maximum throughput and consistent product sizing.
Step 4 — Multi-Stage Integration Crushed material transfers to downstream cone crushers or hammer impact crushers for secondary and tertiary reduction. Belt conveyors and vibrating screens complete the closed-circuit system under centralized control.
Solution Design: material analysis, hardness testing, throughput calculation, process flow diagrams, and equipment layout drawings provided before order.
Equipment Manufacturing: ISO-certified production, factory acceptance testing including V-belt alignment, hydraulic pressure validation, and no-load run with complete test documentation.
Installation and Commissioning: certified field engineers supervise mechanical installation, electrical integration, and full-load commissioning; hands-on operator training on discharge adjustment and lubrication included.
Operations and Maintenance: remote monitoring, preventive maintenance scheduling, regional spare parts supply, on-call technical support, and customized long-term service agreements.

Case 1 — Iron Ore Primary Crushing, Southeast Asia A state-owned mining company in Southeast Asia deployed two DLEV140 Durable Jaw Crushers as primary crushers in a 600 TPH iron ore processing line. The units consistently delivered 650 tons per hour at a 200mm discharge setting, feeding downstream cone crushers for secondary reduction. The hydraulic double wedge adjustment allowed operators to fine-tune product size in under 5 minutes without halting production. The elastic limit shock absorption device significantly reduced foundation vibration, extending the concrete foundation inspection interval from quarterly to annual.
Case 2 — Bluestone Aggregate Production, Middle East A large aggregate producer in the Middle East installed a DLEV160 Durable Jaw Crusher for primary bluestone crushing in a 900 TPH quarry operation. Processing bluestone with compressive strength up to 280MPa, the crusher maintained a steady 850 tons per hour at a 250mm discharge setting. The automatic intelligent lubrication system with quantitative oil injection reduced maintenance time by 35% compared to manual lubrication practices. The integrated motor base reduced total installation time by 5 days versus separate motor foundation construction.
Case 3 — Highway Construction Aggregate, West Africa A road construction contractor in West Africa commissioned two DLEV125 Durable Jaw Crushers at a temporary quarry site producing sub-base aggregate for a 200km highway project. Each unit delivered 450 tons per hour of graded aggregate, with the modular design enabling complete site relocation in under 10 days when the project moved to the next section. The contractor reported 40% lower fuel consumption per ton crushed compared to their previous mobile jaw crusher setup.
Q1: How does the Durable Jaw Crusher reduce operating costs?
The automatic intelligent lubrication system provides precise quantitative oil injection, eliminating manual labor and extending component life. The elastic limit shock absorption reduces frame and foundation fatigue. The hydraulic double wedge adjustment eliminates shim-based adjustment, while the V-shaped cavity maximizes throughput per energy unit. Combined, these deliver significantly lower cost per ton crushed.
Q2: Can this Durable Jaw Crusher handle diverse materials across different industries?
Yes. The hydraulic double wedge enables rapid discharge adjustment from 90mm to 300mm, producing different sizes for construction, road base, or mineral feed. Optimized crushing structure handles abrasive iron ore and softer limestone with equal reliability. Large bearings and hydraulic tie rod pre-tightening maintain alignment under bluestone impact loads while delivering fine discharge for mineral processing.
Q3: Can Zhongyu Dingli provide a complete Durable Jaw Crusher turnkey solution?
Yes. A full turnkey package includes vibrating grizzly feeder, DLEV jaw crusher, belt conveyors, vibrating screen, downstream cone crusher or hammer impact crusher, and centralized PLC control. We deliver integrated design through commissioning with process flow diagrams and capacity guarantee testing at project completion.
