5TPH Granite Stone Crusher Basalt Crusher For High Hardness Rock

Portable granite and basalt crusher for high-hardness rock

1.Product Introduction Portable Stone Crusher

The Portable Granite and Basalt Crusher is a specialized crushing solution engineered to overcome the extreme compressive strength of high-hardness volcanic and metamorphic rocks. Granite and basalt are notoriously abrasive, causing rapid wear in standard equipment; this unit addresses that challenge with reinforced V-shape crushing chambers and high-manganese alloy components. Mounted on a heavy-duty mobile chassis, it provides the mobility required to follow the quarry face while delivering the crushing force typically reserved for massive stationary installations.

2.Application Portable Stone Crusher

• Hard Rock Quarrying: Primary reduction of granite, basalt, gabbro, and diorite for high-specification construction projects.

• Railway Ballast Production: Crushing volcanic rock to the precise, angular specifications required for high-speed rail beds.

• Pavement Engineering: Manufacturing durable, wear-resistant aggregates for high-volume asphalt and concrete highways.

• Hydropower & Dam Construction: On-site processing of localized hard rock deposits for massive structural concrete pours.

3.Working Principle Portable Stone Crusher

• Deep-Chamber Compression: The unit utilizes a primary Heavy-Duty Jaw Crusher with an optimized "deep-chamber" design. This allows for a larger feed size and a sharper crushing angle, which is essential for fracturing the crystalline structure of granite.

• High-Inertia Flywheels: Dual balanced flywheels store massive kinetic energy, providing the "peak force" necessary to crush through basalt boulders without stalling the engine or motor.

• Wedge Adjustment System: Instead of manual shims, a hydraulic wedge system allows operators to change the Closed Side Setting (CSS) in seconds, controlling the output size even as the abrasive rock wears down the plates.

• Heavy-Duty Grizzly Bypass: A vibrating grizzly feeder removes undersized material and abrasive fines before they enter the chamber, reducing unnecessary wear on the jaw plates and increasing overall throughput.

4.Advantages Portable Stone Crusher

• Exceptional Wear Resistance: Equipped with 22% Manganese + Chrome alloy jaw plates, specifically formulated to handle the high silica content of granite and the toughness of basalt.

• Robust Mobilization: Features a reinforced "I-beam" chassis and heavy-duty axles or tracks, designed to support the intense weight and vibration of hard-rock crushing.

• High Reduction Ratio: Capable of reducing large ROM (Run of Mine) feed down to a manageable size in a single pass, simplifying the secondary crushing stage.

• Intelligent Overload Protection: The toggle plate acts as a mechanical fuse, and the hydraulic system provides "tramp release" to prevent structural damage from uncrushable materials like drill bits or loader teeth.

• Modular Power Plant: Available with a "Dual Power" option (Diesel-Electric), allowing the unit to run on its own engine in remote quarries or switch to local grid power to reduce operating costs.
