• Introduction to Multi-Cylinder Hydraulic Cone Crushers

  The multi-cylinder hydraulic cone crusher is a piece of medium-to-fine crushing equipment evolved from the traditional spring cone crusher. By utilizing 4 to 8 hydraulic cylinders for coordinated control, it achieves precise discharge opening adjustment and "tramp iron" protection. It is gradually replacing traditional spring-type and single-cylinder hydraulic models to become the mainstream choice in the high-end crushing market.

  Four Key Technical Advantages

  1. Production Capacity Increased by Over 30%: Multi-cylinder linkage precisely controls the crushing chamber, resulting in significantly higher output compared to single-cylinder models.

  2. Intelligent Hydraulic System: Features one-touch discharge opening adjustment, automatic pressure relief for tramp iron protection, and automatic compensation for liner wear—all without stopping the machine.

  3. Energy Consumption Reduced by 15–20%: Employs the principle of inter-particle (lamination) crushing, where material undergoes repeated compression and grinding within the chamber, offering significant energy savings compared to impact crushing.

  4. Excellent Product Shape: Needle-and-flake content is less than 10%, meeting the stringent aggregate requirements for high-grade concrete used in high-speed railways and expressways.

  Model Range

  The series covers six size classes ranging from HP100 to HP800. Each model offers five chamber configurations—EC (Extra Coarse), C (Coarse), M (Medium), F (Fine), and EF (Extra Fine)—to suit various feed and discharge requirements. The flagship HP800 model boasts a maximum processing capacity of 1,200 t/h and an installed power of 630 kW.

• Application Scenarios for Multi-Cylinder Hydraulic Cone Crushers

  Multi-cylinder hydraulic cone crushers are designed for the medium-to-fine crushing stage. Their core strengths lie in high crushing force and precise particle size control. The following four scenarios represent their typical applications:

  1. Medium-to-Fine Crushing of High-Hardness Ores (Granite / Basalt / Diabase)

  Crushing hard rock with a Mohs hardness of 6–7 and a compressive strength of 150–300 MPa is where the multi-cylinder hydraulic cone crusher excels.

  • Compared to spring cone crushers: 30% higher capacity; liner lifespan extended due to inter-particle (lamination) crushing.

  • Compared to single-cylinder hydraulic crushers: more stable gyratory path of the moving cone and more uniform product gradation.

  Typical configuration: PE900×1200 Jaw Crusher (primary) → HP400 Cone Crusher (secondary) → HP300 Cone Crusher (tertiary).

  2. Large-scale sand and aggregate production lines (for commercial concrete plants / infrastructure supply)

  Large-scale aggregate lines with daily outputs of 3,000–10,000 tons demand extremely high equipment uptime and superior product particle shape.

  • Low flaky and elongated particle content (<10%) is a key selling point of multi-cylinder hydraulic cone crushers—meeting standards for high-grade (C50/C60) concrete aggregates.

  • Automatic hydraulic compensation for liner wear eliminates the need to stop production for discharge setting adjustments, enabling 24-hour continuous operation.

  Typical configuration: Vibrating Feeder → Jaw Crusher → HP500 Crusher (secondary) → Vibrating Screen → Impact Crusher (sand making).

  3. Iron ore / Non-ferrous metal ore processing

  Primary crushing stages for metal ores (iron, copper, gold, etc.) require uniform particle size to enhance the efficiency of downstream ball milling.

  • Multi-cylinder hydraulic cone crushers deliver stable discharge sizing (discharge opening fluctuation within ±2mm), ensuring consistent ball mill feed and reducing grinding energy consumption by 10–15%.

  • Rapid tramp iron protection (automatic pressure relief upon encountering foreign objects like drill bits or bucket teeth) prevents unplanned downtime.

  Typical configuration: Jaw Crusher (primary) → HP400/HP500 Crusher (secondary) → HP300 Crusher (tertiary) → Ball Mill.

  4. Mine tailings / Waste rock reprocessing (solid waste resource utilization)

  Crushing mine overburden and waste rock for use as construction aggregate represents a growing market driven by recent environmental policies.

  • Waste rock composition is complex (containing rocks of varying hardness), making tramp iron protection crucial.

  • The principle of inter-particle (lamination) crushing ensures more uniform breakage of mixed soft and hard materials, avoiding "selective crushing."

  • Integration with mobile crushing stations enables on-site processing, allowing waste rock to be treated without leaving the mine site.
