The DLD Series Single-Cylinder Hydraulic Cone Crusher, independently developed and designed by Zhongyu Dingli, is a premium medium-to-fine crushing solution for mining and aggregate processing lines. Available in two series — DLDS for secondary/medium crushing and DLDH for tertiary/fine crushing — this equipment covers a processing capacity range of 25 to 2,181 tons per hour with a precisely controllable discharge opening between 4 and 41 millimeters.
Engineered for materials with hardness below 16 on the Platt scale, the DLD series efficiently processes iron ore, metal ore, granite, cobblestone, limestone, and basalt. The crusher integrates seamlessly with upstream feeders, jaw crushers, standard cone crushers, and hammer impact crushers to form a flexible, multi-stage crushing system adaptable to diverse production demands and ore types.
Suitable Industries: Cement, building materials, metal and non-metal mining
Recommended Materials: Iron ore, basalt, limestone, hardness ≤16 on Platt scale
Processing Capacity: 25–2,181 T/H | Discharge Size: 4–41 mm
Spiral Bevel Gear Transmission — The DLD series adopts spiral bevel gear drive, offering higher load-bearing capacity, smoother transmission, and lower operating noise compared to conventional gear systems.
Laminated Crushing Principle — Unlike traditional cone crushers, this equipment employs laminated crushing technology. Crushing occurs between materials rather than relying solely on metal-to-material extrusion, which not only improves output and efficiency but also optimizes finished product particle shape to a cubic form.
Overload Protection System — The hydraulic system maintains a large pressure margin during normal operation, ensuring high reliability. When overload occurs, the machine triggers an alarm signal promptly.
Positive Pressure Dust Prevention — Equipped with a U-T dust-proof sealing system, the positive pressure dust-proof device prevents lubricating oil contamination that could damage bearings, extending both lubricant and equipment service life.
Lubricated Bearing Design with Oil Wedge — The bearing features large load-bearing capacity, strong anti-adhesion capability, and excellent adaptability to harsh working conditions. The oil wedge design forms a lubricating oil film between the shaft and bearing, avoiding direct friction, reducing heat generation, and extending bearing service life.
Integrated Hydraulic & Lubrication Design — The hydraulic station and lubrication station adopt an integrated design, saving installation space and facilitating operation and maintenance. Optimized tank volume means oil consumption is only 1/3 of conventional hydraulic lubrication stations of the same specification, significantly reducing daily production costs.
Intelligent Control System — The automatic control system provides multiple operation modes for flexible selection based on production requirements. It continuously monitors actual internal load and displays various operating parameters in real time. When liners are worn to the point of being unusable, the control panel automatically displays and sends an alarm signal for timely maintenance.
High Production Efficiency — Combining crushing stroke, crushing speed, and laminated crushing principle, the equipment improves production capacity and work efficiency. With the same large-end diameter of the moving cone, output increases by approximately 35%-60%.
Stable Particle Shape — The optimized crushing chamber shape and constant-output liner design achieve constant discharge opening control. This ensures more stable finished product particle shape while extending liner service life by 20%.
Automatic Cavity Cleaning — When uncrushable materials such as iron blocks enter the chamber, the hydraulic cylinder automatically adjusts the discharge gap to expel them, achieving automatic cavity cleaning.
Easy Maintenance — Simple and compact structure, stable operation, and low failure rate enable convenient and quick maintenance.

A medium and fine crushing project for an iron ore beneficiation plant in West Africa demonstrates the DLD Series Single Cylinder Hydraulic Cone Crusher's capability in processing high-hardness metallic ores.
Project Location: West Africa
Project Scale: Annual processing capacity of 3 million tons of raw ore
Application: Iron ore beneficiation — medium and fine crushing stages
Material Characteristics: High-hardness iron ore with compressive strength up to 350 MPa and significant abrasiveness
Core Equipment: DLD Series Single Cylinder Hydraulic Cone Crusher configured with DLDS (secondary) and DLDH (tertiary) models
Key Advantages: The Single Cylinder Hydraulic Cone Crusher for Ore Mining utilizes laminated crushing technology to ensure efficient processing of extremely hard materials while maintaining consistent product size. The spiral bevel gear transmission provides superior load-bearing capacity for continuous high-capacity operation. The hydraulic cylinder's over-iron protection function automatically drops the moving cone when uncrushable materials enter, then resets automatically.
Maintenance Benefits: The integrated hydraulic and lubrication design saves installation space, and oil consumption is only 1/3 of conventional stations. The U-T positive pressure dust seal effectively prevents lubricating oil contamination in this dusty mining environment.
Customer Feedback:
"Processing high-grade iron ore in West Africa demands equipment that can handle extreme hardness. The DLD series single cylinder hydraulic cone crusher has delivered consistent performance with minimal maintenance intervention. The automatic cavity clearing function has been essential for protecting the equipment when occasional tramp materials pass through. The laminated crushing technology gives us superior product shape for downstream beneficiation." — Plant Manager, West African Iron Ore Beneficiation Project
The DLD Series Single Cylinder Hydraulic Cone Crusher is designed to process a wide range of materials including iron ore, metal ore, granite, cobblestone, limestone, basalt, and quartzite. It is suitable for materials with compressive strength up to 350 MPa and hardness below 16 on the Platt scale. The equipment offers DLDS series for medium/coarse crushing and DLDH series for fine crushing, with multiple cavity types (S1/S2 for DLDS; H1/H2/H3 for DLDH) allowing optimal configuration based on feed particle size and desired output. For specific applications, our team provides customized process solutions based on detailed material analysis.
The DLDS series is designed for secondary/medium crushing with larger feed sizes (up to 450mm) and coarser discharge settings (19–41mm), making it ideal for the second stage of aggregate production. The DLDH series is optimized for tertiary/fine crushing with smaller feed sizes (up to 295mm) and finer discharge settings (as low as 4–16mm). Within each series, multiple cavity types are available — S1 (extra coarse) and S2 (medium coarse) for DLDS; H1 (fine), H2 (medium fine), and H3 (extra fine) for DLDH. Selection depends on target output volume, raw material hardness, and required discharge particle size. Our team provides customized process solutions to help you select the optimal configuration based on your feed material, desired output specifications, and production targets.
