Product Overview

The Multi-cylinder Hydraulic Cone Crusher represents a significant leap forward in rock and ore crushing technology. Unlike traditional spring cone crushers or single-cylinder models, this advanced machine incorporates multiple hydraulic cylinders around the crushing chamber, providing superior control over the crushing process. It is engineered for high-performance secondary, tertiary, or quaternary crushing stages in mining, aggregate, and industrial mineral operations. By leveraging intelligent hydraulic control systems and an optimized laminating crushing principle, it delivers unparalleled productivity, exceptional product shape, and remarkable operational stability.

Key Features & Advantages

• 1. Advanced Hydraulic Control System

  • Automated Operation & Setting Adjustment: The multi-cylinder design allows for full hydraulic adjustment of the crusher’s closed-side setting (CSS) under load. This enables remote control and real-time adjustment to compensate for wear or change product specifications without stopping the machine.
  • Over-Iron Protection & Chamber Clearing: If an uncrushable object (tramp iron) enters the chamber, the hydraulic system automatically lowers the mantle to release it, then returns to the original setting to resume operation. This prevents serious damage and reduces downtime.
  • Dual-Acting Hydraulic Cylinders: The cylinders not only provide clamping force but also serve as safety devices, offering more reliable and responsive protection compared to mechanical spring releases.

• 2. Superior Crushing Performance & Product Shape

  • Laminating Crushing Principle (Inter-Particle Crushing): The unique mantle and concave design, combined with high speed and stroke, promotes rock-on-rock crushing. This results in a more cubicle and well-graded end product with a significantly reduced flakiness index, ideal for high-quality concrete and asphalt aggregates.
  • High Efficiency & Capacity: The optimized crushing cavity and high power enable a much higher crushing force and throughput compared to crushers of similar size.

• 3. Enhanced Reliability and Durability

  • Robust Structure: The main frame is heavily reinforced to withstand extreme crushing forces.
  • High-Quality Wear Parts: Manganese steel mantles and concaves are designed for long service life and are easily replaceable.
  • Dust Seal & Ring System: A multi-stage labyrinth seal and a positive pressure grease ring effectively keep dust and contaminants out of the internal lubrication system, protecting bearings and ensuring smooth operation.

• 4. Intelligent Automation

  • PLC (Programmable Logic Controller) Integration: The crusher can be equipped with an automatic control system that monitors key parameters like main shaft position, pressure, temperature, and motor power. It can automatically optimize the feed rate and crusher load for peak efficiency.

• 5. Easy Maintenance

  • Top-Service Design: All service points, including the hydraulic system and the main shaft, are accessible from the top of the crusher, simplifying inspection and maintenance tasks and improving safety.

Applications

Multi-cylinder Hydraulic Cone Crushers are versatile and are primarily used in:

• 1. Mining & Metallurgy: Crushing of iron ore, copper ore, gold ore, manganese ore, and other metal and non-metal ores.

• 2. Aggregates & Quarries: Production of high-quality crushed stone for concrete, asphalt, and road base in granite, basalt, and limestone quarries.

• 3. Construction: Crushing of construction waste for recycling and reuse.

• 4. Industrial Minerals: Processing of materials like quartz, feldspar, and calcite.

FAQ: Multi-cylinder hydraulic cone crusher

Q1: How is a multi-cylinder model different from a single-cylinder hydraulic cone crusher?

A: The primary difference is the hydraulic system. A single-cylinder crusher uses one cylinder for both support and adjustment, with a simpler design suited for secondary crushing. Multi-cylinder crushers use several cylinders for more precise, powerful, and independent control over the crushing process, making them ideal for finer crushing stages and producing superior product shape.

Q2: What is the main advantage of the hydraulic system?

A: The main advantages are safety (automatic release of tramp iron), convenience (remote adjustment of discharge setting), and stability (consistent performance and product quality).

Q3: How often do the wear parts (mantle and concave) need to be replaced?

A: Wear life depends entirely on the abrasiveness of the material being crushed, the feed size, and the CSS. It can range from a few weeks to over a year. Regular monitoring of product size and crusher power draw is the best way to determine replacement timing.

Q4: Can this crusher handle sticky or moist materials?

A: While they are high-performance machines, sticky materials can pose a challenge by causing packing in the crushing chamber. Proper feed preparation (e.g., scalping) and potentially a chamber-clearing cycle can help mitigate this. It’s best to consult with the manufacturer for specific material applications.

Q5: Is the automation system complex to operate?

A: No. Modern PLC-based control systems are designed with the operator in mind. They feature user-friendly interfaces (HMIs) that display all critical parameters and often include automated operating modes that simplify daily operation.
