200TPH Mobile Cone Crusher Hard Rock Quarrying Portable Cone Crusher

Heavy duty mobile cone crusher for hard rock quarrying

1.Product Introduction Portable Stone Crusher

The Heavy-Duty Mobile Cone Crusher is a high-performance, track-mounted crushing plant engineered specifically for secondary and tertiary reduction of the world’s hardest materials, including granite, basalt, and abrasive quartz. Unlike primary jaw crushers, this unit focuses on precision and shape, utilizing high-pressure hydraulic crushing technology to produce consistent, cubical aggregates. Built for extreme quarrying environments, it combines the mobility of a tracked vehicle with the crushing force of a stationary plant, allowing operators to relocate the machine directly to the rock face, thereby slashing haulage costs and streamlining the production of high-specification construction materials.

2.Application Portable Stone Crusher

• Hard Rock Quarrying: Secondary or tertiary crushing of high-strength rocks like basalt, granite, and gabbro for railway ballast and high-grade concrete.

• Mining Operations: Reduction of metallic ores (iron, copper, gold) to optimal sizes for downstream milling and leaching.

• Aggregate Production: Manufacturing high-quality, cubical "chips" for asphalt road surfacing and structural engineering.

• Contract Crushing: Ideal for multi-site operations where rapid deployment and high-tonnage output are required across different geographical locations

3.Working Principle Portable Stone Crusher

• Inter-Particle Crushing: Ore is fed into the crushing chamber where a high-speed eccentric shaft rotates the inner "mantle." The rock is crushed against the outer "concave" not just by compression, but by the friction of rock-on-rock, which improves the final particle shape.

• Hydraulic Tramp Release: To protect the machine, a hydraulic system automatically opens the chamber if "tramp iron" (unbreakable metal) enters, allowing it to pass safely before returning to the preset gap.

• Closed-Circuit Screening: Often integrated with a return conveyor and on-board screen, the unit can recirculate oversize material back into the cone, ensuring 100% of the output meets the target specification.

• Automated Control: An on-board PLC monitors the feed level and mantle pressure in real-time, automatically adjusting the feed rate to maintain a "choke-fed" condition for maximum efficiency.

4.Advantages Portable Stone Crusher

• Superior Product Shape: The high-energy "inter-particle" crushing action produces a highly cubical product with minimal flaky or elongated pieces, meeting strict international aggregate standards.

• Extreme Mobility: Heavy-duty tracks and a wireless remote control system allow for rapid maneuvering over steep quarry grades and uneven terrain.

• Intelligent Hydraulic Adjustment: The "CSS" (Closed Side Setting) can be adjusted via a touchscreen while the machine is running, allowing for instant changes in product size without stopping production.

• Fuel Efficiency & Power: Equipped with advanced diesel-electric or direct-drive engines that optimize fuel consumption while providing the massive torque required for hard rock reduction.

• Rugged Durability: Reinforced with high-manganese liners and heavy-duty chassis frames designed to absorb the intense vibrations of high-pressure crushing.
