Single-Cylinder Hydraulic Cone Crusher

The HST Series Single-Cylinder Hydraulic Cone Crusher is a high-efficiency secondary and tertiary size reduction unit. Engineered with a bottom-mounted hydraulic cylinder, this machine seamlessly integrates main shaft support, CSS (Closed Side Setting) adjustment, and tramp iron protection into a single, highly reliable hydro-mechanical system. It delivers consistent lamination crushing for metallic mining and high-grade aggregate production while keeping mechanical complexity and maintenance overhead to a minimum.

Heavy-Duty Processing Applications

Designed for continuous, high-tonnage size reduction in rigorous mineral processing plants and commercial aggregate quarries.

Commercial Aggregate Quarries

Processes abrasive hard rocks like granite and diabase into high-quality, cubical aggregates with minimal flakiness, suitable for highway and structural concrete.

Metallic Ore Beneficiation

Serves as a robust secondary or tertiary crusher in iron, copper, and gold mining circuits, effectively reducing the feed size for downstream ball and SAG mills.

Infrastructure & Railway Ballast

Produces highly consistent, specification-grade ballast and crushed stone required for mega-infrastructure and high-speed railway projects.

Slag & Industrial Mineral Processing

Efficiently crushes industrial metallurgical slag and non-metallic minerals, utilizing its tramp iron release system to prevent mechanical damage from uncrushable alloys.

Mechanical & Structural Advantages

Integrated Bottom Cylinder Design

A single heavy-duty hydraulic cylinder positioned at the base supports the main shaft. This structural configuration consolidates cavity clearing, CSS adjustment, and overload protection, drastically reducing the number of external moving parts compared to multi-cylinder designs.

Optimized Lamination Crushing

The steep crushing cavity and synchronized eccentric motion induce inter-particle lamination crushing. This mechanics-driven approach increases the yield of fine fractions and improves the overall cubical shape of the finished product while reducing liner wear.

Automated PLC & CSS Control

Equipped with an advanced PLC and touchscreen interface. The control system continuously monitors hydraulic pressure, motor load, and lubrication parameters, enabling fully automated Closed Side Setting (CSS) adjustments to maintain continuous production thresholds.

Rapid Tramp Iron Release

If uncrushable materials (tramp iron) enter the cavity, the hydraulic accumulator instantly reacts, dropping the main shaft to open the discharge setting. Once the iron passes, the cylinder automatically returns the shaft to its original calibrated position.

Combined Hydraulic & Lube Station

Features an integrated skid-mounted station for both hydraulic actuation and mechanical lubrication. It provides continuous oil flow to the eccentric bearings and thrust bearings, complete with automated temperature sensors and cooling loops.

Heavy-Duty Cast Steel Frame

The upper and lower main frames are manufactured from high-strength cast steel, engineered via finite element analysis (FEA) to withstand extreme, continuous compressive stresses in severe mining environments.

How It Works On-Site

HST Single-cylinder Hydraulic Cone Crusher
  • 1

    Horizontal Torque Transmission

    The electric motor drives the horizontal transmission shaft via V-belts. The pinion gear on the horizontal shaft engages with the large bevel gear, converting the motion to rotate the eccentric sleeve.

  • 2

    Eccentric Gyratory Motion

    As the eccentric sleeve rotates, it forces the main shaft and the moving cone (mantle) to perform a continuous gyratory pendulum motion within the stationary upper frame.

  • 3

    Continuous Cavity Compression

    Material entering the top of the crushing cavity is squeezed, fractured, and sheared between the gyrating moving cone and the fixed concave liner (bowl liner).

  • 4

    Hydro-Pneumatic Discharge Control

    Crushed particles fall through the discharge opening. The bottom hydraulic cylinder simultaneously supports the main shaft and allows operators to adjust the discharge gap (CSS) precisely via the PLC to control the final aggregate sizing.
