A Hassle Free Solution for Medium and Fine Crushing in Mining and Aggregate Operations
Cone Crusher Equipment Overview
The DLD Series Single-Cylinder Hydraulic Cone Crusher is a medium- and fine-crushing solution specifically designed for ore processing. It plays a pivotal role in aggregate production lines and mineral processing plants—receiving material from the primary jaw crusher and performing medium and fine crushing operations to meet requirements for product particle shape, gradation, and production capacity. The equipment comprises two sub-series: the DLDS medium-crushing type and the DLDH fine-crushing type, covering a wide capacity range of 25–2,181 tons per hour, with a precisely controllable discharge opening between 4 and 41 millimeters. Suitable for the medium and fine crushing of medium-to-high-hardness ores with a Mohs hardness of 16 or below, the series covers materials such as iron ore, basalt, limestone, granite, and river pebbles, and is widely used in cement plants, building materials production lines, and metal and non-metal mineral processing.
We specialize in the R&D, production, and sales of core equipment for mining and mineral processing, construction aggregate processing, and infrastructure engineering, covering a full range of products, including the DLKPC double-chamber hard rock crusher, DLHGC horizontal gyratory crusher, DLHPT multi-cylinder cone crusher, and jaw crushers.
Cone Crusher Equipment Highlights
Laminated crushing increases production capacity by 35%–60%. The crushing chamber is filled with material; as the moving cone swings, large quantities of rock are compressed, ground, and bent against one another, achieving “rock-on-rock” crushing rather than single-particle compression. This results in high-quality cubic-shaped final products with low flake and needle content, while ensuring more uniform liner wear and extending service life by 20%.
Helical bevel gear drive, low noise and high load capacity. The meshing is smoother than traditional straight-tooth bevel gears, offering higher load capacity and lower operating noise, thereby resolving the issues of gear tooth breakage and excessive vibration in older cone crushers after prolonged use. During overload conditions, the hydraulic system automatically triggers an alarm to protect core components.
Integrated hydraulic and lubrication station reduces oil consumption by two-thirds. Combining two systems into one saves installation space and significantly simplifies piping. The optimized oil tank requires only one drum of lubricating oil—compared to three drums in traditional equipment—significantly lowering daily production costs. The over-iron protection system, controlled by a hydraulic cylinder, automatically discharges foreign objects and resets, offering greater sensitivity and faster reset times than the mechanical over-iron protection found in spring-loaded cone crushers.
Intelligent control system enables remote monitoring to reduce labor requirements. It monitors parameters such as load, current, and temperature in real time, provides automatic alerts for liner wear and replacement, and supports remote viewing of operating status and historical data via computer or mobile phone, significantly reducing the frequency of on-site inspections and lowering labor costs.
Simple structure, low failure rate. A single hydraulic cylinder integrates three major functions: discharge opening adjustment, over-iron protection, and chamber cleaning. Compared to multi-cylinder models, the structure is more compact with fewer potential failure points, making maintenance convenient and ensuring high production line uptime.
Cone Crusher Application Scenarios
Medium and fine crushing stages in sand and gravel aggregate production lines to produce high-grade construction aggregates; medium and fine crushing processes in the beneficiation of iron ore and metal/non-metal ores; crushing and processing of limestone and basalt in cement plants and the building materials industry; medium and fine crushing and shaping of high-hardness materials such as granite and river pebbles.
Cone Crusher Customized Process Flow
For typical medium and fine crushing operations of ores, we recommend a two-stage closed-circuit process using a jaw crusher and a cone crusher: Raw material is fed into the jaw crusher for primary crushing after de-silting via a vibrating feeder; the primary crushed material is classified by a vibrating screen, with the oversize material entering the DLD single-cylinder hydraulic cone crusher for secondary crushing, where layer-crushing ensures high throughput and excellent particle shape; The cone crusher discharge forms a closed-circuit loop with the screening process; qualified material is sent to storage, while oversized material is returned to the cone crusher for re-crushing. The DLDS medium-crushing model and DLDH fine-crushing model can be flexibly combined based on the target discharge size to achieve step-by-step crushing. The overall capacity ranges from 25 to 2,181 tons per hour, accommodating the needs of production lines of various scales.

Cone Crusher Overseas Project Case Studies
A medium and fine crushing project for an iron ore beneficiation plant in West Africa, with an annual processing capacity of 3 million tons of raw ore. The client is a major local mining enterprise. The ore consists of high-hardness iron ore, which places extremely high demands on the continuous operation rate of the medium and fine crushing equipment and the final product particle size. Our company supplied two DLDS medium-crushing and three DLDH fine-crushing single-cylinder hydraulic cone crushers to form a two-stage closed-circuit crushing process. After commissioning, the medium-crushing units stably produced 800–1,200 t/h, while the fine-crushing output was consistently maintained at 8–15 mm. The laminar crushing process ensured excellent product shape with flake and needle content below 10%, meeting the ideal feed size requirements for the downstream ball mill. The integrated hydraulic lubrication station, designed to reduce oil consumption by two-thirds, performed reliably in Africa’s high-temperature environment. The intelligent control system enabled remote monitoring from the central control room, significantly reducing on-site inspection labor. Customer feedback: The equipment has operated for two years without major failures; liner life and oil consumption far exceeded expectations, and remote monitoring has greatly helped reduce O&M costs at the African mining site.

Cone Crusher Frequently Asked Questions
Q: What are the advantages of single-cylinder hydraulic cone crushers over multi-cylinder models in medium and fine crushing of ore?
A: The core advantage of single-cylinder hydraulic cone crushers in medium and fine ore crushing lies in the laminar crushing principle—compared to traditional single-particle compression models, they increase production capacity by 35%–60%, produce high-quality cubic-shaped final products, and have low flaky and needle-like particle content. Compared to multi-cylinder models, they feature a simpler structure, fewer potential failure points, and easier maintenance. A single hydraulic cylinder at the bottom integrates three key functions: discharge opening adjustment, iron protection, and chamber cleaning. The integrated hydraulic and lubrication station saves space and reduces oil consumption by two-thirds.
