Product Introduction

The Single-cylinder Hydraulic Cone Crusher is a highly efficient and advanced crushing machine that integrates mechanical, hydraulic, electrical, and intelligent control technologies. It is designed for the secondary, tertiary, and quaternary crushing stages in mining and aggregate production. Its core innovation lies in the use of a single hydraulic cylinder to perform all the key functions: adjusting the discharge opening, clearing the crushing chamber in case of iron passing or overload, and providing reliable overload protection.

This crusher is renowned for its simple structure, high automation, excellent product shape, and consistent performance, making it a preferred choice for medium and fine crushing of high-hardness materials like granite, basalt, and iron ore.

Key Features & Advantages

• 1. Simple and Robust Structure: With fewer mechanical parts compared to multi-cylinder models, the design is more straightforward, leading to lower initial costs, easier maintenance, and higher reliability.

• 2. High Automation and Intelligence: Equipped with an automated control system, it allows for real-time monitoring of key parameters like main shaft position, motor power, and crushing force. The system can automatically adjust the crusher settings for optimal performance and send alerts for maintenance.

• 3. Excellent Product Shape: The unique laminating crushing principle (rock-on-rock and rock-on-iron) produces well-shaped, cubic end products with a low flakiness index, which is highly desirable for the construction and concrete industries.

• 4. Convenient Adjustment and Protection: The discharge opening is easily adjusted via the hydraulic cylinder, which also serves as a safety device. When uncrushable material (tramp iron) enters the chamber, the hydraulic cylinder automatically lowers, allowing it to pass, and then quickly returns to the original setting, ensuring continuous operation.

• 5. High Crushing Efficiency: The optimized crushing cavity and high swing frequency ensure high output capacity and superior reduction ratios.

• 6. Easy Maintenance: All maintenance operations, from replacing liners to inspecting internal parts, can be performed from the top of the crusher, simplifying the process and reducing downtime.

Industry Applications

Single-cylinder hydraulic cone crushers are versatile and widely used in:

• 1. Mining Industry: For fine crushing of various ores, such as iron ore, copper ore, gold ore, manganese ore, and non-ferrous metals.

• 2. Aggregate and Sand Production: Producing high-quality crushed stone and artificial sand for concrete, asphalt, and construction aggregates.

• 3. Quarrying: Secondary and tertiary crushing of granite, basalt, limestone, and other rocks.

• 4. Industrial Minerals: Processing of raw materials for cement, abrasives, and other industrial applications.

Key Differences: Single-cylinder vs. Multi-cylinder Hydraulic Cone Crusher

Summary: Choose a Single-cylinder crusher when your priority is excellent product shape, lower cost, and simpler operation for medium-hard to hard materials. Choose a Multi-cylinder crusher for higher capacity, larger feed size, and more robust performance in primary or heavy-duty secondary crushing stages.

FAQ: Single-cylinder hydraulic cone crusher

Q1: How often do the wear parts (mantle and concave) need to be replaced?

A: The service life of wear parts depends on the abrasiveness of the material being crushed. It can range from a few hundred to over a thousand hours. Monitoring the crusher’s power draw and product size can help determine the optimal replacement time.

Q2: Can it handle tramp iron or uncrushable objects?

A: Yes. The hydraulic system is designed for iron passing. When an uncrushable object enters the chamber, the hydraulic cylinder will automatically release it and then reset, minimizing damage and downtime.

Q3: Is the discharge opening adjustment made during operation?

A: Yes, one of the key advantages is that the CSS (Closed Side Setting) can be adjusted hydraulically under load, allowing for quick and easy product size changes without stopping the crusher.

Q4: What kind of maintenance is required regularly?

A: Regular maintenance includes checking and changing the hydraulic oil and lubricating oil, inspecting the wear of liners and other internal parts, and ensuring all electrical connections are secure. The simplicity of the single-cylinder design makes these tasks more straightforward.

Q5: Is the product shape suitable for making high-quality concrete sand?

A: Absolutely. The laminating crushing action produces well-shaped, cubic particles with minimal needle-like pieces, which is ideal for producing high-quality manufactured sand for concrete and asphalt.
