Single Cylinder Hydraulic Cone Crusher

Product Description

Product Overview

The Single Cylinder Hydraulic Cone Crusher (similar to the Sandvik S/CH style) is an advanced crusher. Its design is revolutionary: the main shaft is supported by a hydraulic cylinder at the bottom. This cylinder does three jobs: it supports the cone, adjusts the discharge setting (CSS), and acts as the safety release system. This integration makes the machine compact and incredibly smart.

Why Choose a Used Single Cylinder?

• Automation on a Budget: New single-cylinder cones are expensive due to the electronics and hydraulics. A used unit gives you access to “Auto-Regulation” technology (Constant Power / Constant Discharge Mode) for a fraction of the cost.
• Low Operating Cost: The liner utilization ratio is very high. The steep cavity means rock flows through quickly, reducing wear per ton.
• Versatility: By simply changing the eccentric bushing and liners, one machine can cover a wide range of production needs (from coarse to extra fine).

Key Technical Features

1. Bottom Hydraulic Cylinder: Automatically raises or lowers the main shaft to adjust the CSS. If pressure spikes, it drops the shaft instantly to pass tramp iron.
2. Steep Crushing Chamber: The steep angle allows for a higher throughput capacity per diameter size compared to multi-cylinder or spring cones.
3. PLC Touch Screen Control: (Depending on the unit’s age) Most come with a control cabinet that visualizes pressure, temperature, and wear data.
4. Direct Drive: Efficient power transmission from motor to crusher.

Applications

• Secondary Crushing: Ideal for high-hardness materials where capacity is key.
• Mining Circuits: Often used as a pebble crusher in SAG mill circuits.

Quality Assurance

For these high-tech machines, we test the Hydraulic Cylinder Seals rigorously (no internal bypassing). We check the Dust Seal Blower (positive pressure air system) which keeps dust out. We also test the PLC Control Cabinet to ensure the sensors and logic are functioning correctly.

Common Customer Questions (FAQ)

• Q: Is the hydraulic system complicated to fix?
  • A: The mechanical part is actually simpler than a spring cone (fewer parts). The hydraulic/electric part requires a basic understanding, but the system is modular and reliable.
• Q: What happens if the seal fails?
  • A: These machines use high-pressure air prevents dust entry. We ensure the blower is working. If the oil gets contaminated, the sensors will alert you to stop, preventing damage.
• Q: Can I control it from my control room?
  • A: Yes, most models have remote terminals that can integrate with your plant’s SCADA system.
• Q: Is it good for sand making?
  • A: It is excellent for “Fine Crushing” (making <10mm material), which increases the efficiency of your VSI sand maker, but it is not a dedicated sand shaper itself.
