Cone Crusher

Material enters the machine through the feed opening and is optimally distributed into the crushing cavity by the feeding system. Driven by powerful Eccentric Gyration, the material is subjected to intensive compressive forces between the mantle and the bowl liner. This triggers a highly effective secondary and tertiary crushing mechanism, where rocks are reduced not only by mechanical compression but also through inter-particle crushing (Laminated Crushing) until the target particle size is reached.

The multi-cylinder hydraulic adjustment system precisely regulates the mantle position and crushing chamber volume. By controlling the piston positions across the hydraulic cylinder array, the discharge gap can be adjusted rapidly and automatically to suit various hard material specifications, while providing instant release protection against uncrushable foreign objects (tramp iron).

To maintain high safety and environmental standards at the mine site, the machine is equipped with an effective labyrinth sealing system to prevent dust leakage. The crushed material is discharged through the discharge opening, where particle size is digitally controlled by the hydraulic system to yield a final product with uniform gradation and premium cubical shape that meets strict construction standards.

Throughout its operational lifecycle, the ZME cone crusher delivers stable performance thanks to its heavy-duty frame structure and robust internal component design. Routine maintenance focused on the hydraulic system ensures high thermal efficiency and an extended service life in demanding quarrying environments.

The structural design of the ZME Hydraulic Cone Crusher is built for extreme durability, consisting of the main frame, adjustment device, adjustment ring, crushing cone, transmission system, eccentric sleeve, and automated auxiliary systems for lubrication and electrical control.

• Advanced Lubrication System: Includes an oil tank, cooling unit, and automatic filter. ZME machines utilize Labyrinth Sealing technology (dry oil or water) which highly effectively prevents mine dust contamination in the lubrication system, significantly extending internal component service life.
• Hydraulic Control Station: Serves as the control hub containing an oil tank with precision indicator sensors, motor pump, filters, accumulators, intelligent control unit, and pressure switches for automatic safety protection. Integrated seamlessly with the local operation control panel.
• Main Frame: Comprises upper and lower frames securely connected by hydraulic cylinders and equipped with wear liners. The lower frame is constructed from an integral steel casting to ensure structural strength under heavy shock loads in mining environments.
• Main Shaft Assembly: The main shaft is precision-engineered using specialized material integration within the lower frame, complete with axial and radial lubrication channels to ensure optimal lubricant flow under high operating temperatures.
• Eccentric Bushing Assembly: Features high-quality high-lead bronze bushings. Equipped with a large ring gear and a forged steel thrust bearing assembly to support stable gyration. Counterweights covered with wear-resistant liners ensure optimal mechanical balance.
• Moving Cone (Mantle): Lined with wear-resistant high-manganese steel, with cavity backings filled with epoxy resin for maximum shock damping. Supported at the base by spherical bearings that work synergistically with the eccentric sleeve for high crushing efficiency.
• Fixed Cone (Bowl Liner): Equipped with a feed hopper and lined with securely locked high-manganese steel wear plates. External trapezoidal threads ensure accurate and stable output gap adjustments.

In non-metallic mineral industries such as limestone, quartz, and feldspar, ZME Cone Crushers play a pivotal role in meeting strict raw material standards for the cement, chemical, and ceramics sectors.

In a 5,000 ton-per-day cement production line, our cone crusher processes limestone by optimizing the eccentric throw and crushing chamber geometry. This enables precise output size control within the 10–30 mm range, which is critical for cement clinker efficiency.

The unique ZME crushing chamber design minimizes over-crushing, reducing unwanted fine dust production while delivering more uniform particles. This advantage is also highly effective in processing quartz for glassmaking and feldspar for ceramics, where particle size consistency is the primary determinant of final product quality.

Major infrastructure projects such as highways and railways impose strict requirements on aggregate durability and particle gradation. A production line integrating ZME Cone Crushers, Impact Crushers (HSI), and vibrating screens provides significant technical advantages, particularly when processing hard rocks such as Basalt.

In high-speed railway construction projects across challenging terrain, the ZME Cone Crusher is deployed for precise secondary crushing, then paired with an Impact Crusher for particle shaping. This collaboration produces aggregates with a Flakiness and Elongation Index below 8% and an Aggregate Crushing Value (ACV) below 12%.

These performance metrics not only meet but exceed strict national and international standards such as ASTM, permanently ensuring the stability of railway track beds and the durability of highway pavements under heavy traffic loads.

1. Commercial Concrete Aggregate Production Line: Commercial concrete demands aggregates with uniform particle gradation and minimal silt content. The hydraulic adjustment system on the ZME Cone Crusher enables high-precision discharge opening tuning down to 0.5 mm to maintain product size stability. Implementing this technology significantly improves the aggregate gradation ratio and reduces concrete slump loss by up to 15%, ultimately enhancing concrete compressive strength and durability.
2. Manufactured Sand (M-Sand) Production Line: With natural sand depletion, manufactured sand serves as the primary sustainable alternative. A production line integrating ZME Cone Crushers, VSI sand-making machines, and sand washing systems delivers optimal performance when processing river gravel or hard rocks. In this setup, the cone crusher performs efficient secondary crushing prior to feeding the VSI unit for shaping. This synergy produces manufactured sand with a Fineness Modulus of 2.6–2.8 and dust content below 5%, fully satisfying international technical standards for high-rise buildings and major infrastructure.
3. Premium High-Quality Aggregate Production Line: Dam projects, water infrastructure, and high-end construction demand strict aggregate specifications. The ZME Cone Crusher operates on the Laminated Crushing principle, where material undergoes repeated inter-particle compression within the crushing chamber. This process yields cubical particles with rough surface textures that establish strong mechanical bonding with cement paste. Using premium aggregates from the ZME system enables concrete to achieve high impermeability ratings, guaranteeing long-term safety and lifespan for concrete structures.
