Product Description

The HTJC430 Stone Crusher is a high-efficiency piece of equipment designed for large-scale crushing operations. Integrating advanced jaw crushing technology with modular design, it is specifically engineered for mining, building materials processing, and infrastructure projects. It can precisely process materials with a Mohs hardness rating of up to 8, such as granite, basalt, and limestone, with a maximum crushing compressive strength of 320 MPa. This provides a stable and reliable solution for the production of high-grade aggregates.

Applications

Mining sector:
Suitable for open-pit coal mines, metal mines, non-metallic mines and other extraction scenarios, serving as core equipment for primary and secondary crushing. Processes primary ores such as granite, basalt and limestone. Capable of reducing large ore blocks into aggregates meeting subsequent processing requirements. Integrates with screening and sand-making equipment to form complete production lines, fulfilling continuous crushing demands for large-scale mining operations while enhancing ore utilisation and extraction efficiency.

Infrastructure Engineering Sector:
Focusing on key infrastructure projects such as high-speed railways, motorways, bridges and tunnels, we provide premium aggregate production solutions. The uniformly graded crushed aggregates can be directly utilised in critical processes including concrete mixing, subgrade laying and pavement pouring, eliminating the need for secondary shaping. These aggregates meet stringent project requirements for strength and particle shape, ensuring both the quality and timely progress of infrastructure construction.

Building materials processing and sand and gravel production sector:
Serving professional aggregate quarries and building materials processing plants, this facility mass-produces construction sand and crushed stone aggregates in various specifications. It supports flexible adjustment of output particle size to accommodate diverse requirements for conventional construction, precast components, and high-strength concrete. The finished product exhibits a cubic particle shape and well-graded composition, meeting standardised production demands within the building materials industry and enhancing enterprises' market competitiveness.

Construction waste recycling sector:
For the processing of construction waste arising from urban renewal and demolition sites, achieving resource recycling. This equipment efficiently crushes concrete blocks, bricks, stones, and discarded road surfaces. The crushed output, after screening, can be utilised as recycled aggregate for road base laying, recycled brick production, and backfill material. This approach aligns with environmental policies, reducing resource wastage and environmental pollution.

Advantages

High-efficiency crushing
Featuring an optimised V-shaped deep cavity design that creates multi-stage crushing zones, throughput increases by 15%-25% compared to conventional models, achieving a crushing ratio of up to 8:1.
Core crushing components are crafted from high-chromium cast iron or high-manganese steel with hardness reaching HRC48-62. Combined with a progressive tooth profile, this ensures 98% uniformity in final product particle shape.
Sturdy and durable
The frame employs heavy-duty welding techniques with stress-relief treatment, paired with forged alloy steel eccentric shafts, delivering a 20% increase in load-bearing capacity and enhanced impact resistance. Upgraded sealing protection effectively blocks dust and moisture ingress, adapting to harsh mining conditions such as high dust levels and humidity, with a comprehensive failure rate below 0.8%. Wear-resistant components exhibit a 2.5-fold increase in service life, with a single set of roller liners or liners achieving 1500-2000 hours in limestone applications, thereby reducing replacement frequency.
Intelligent and Convenient
Equipped with a PLC intelligent control system and pressure sensors, the overload protection response time is ≤0.3 seconds, automatically mitigating risks of material jamming and overpressure.
Featuring a hydraulic clearance adjustment system, it enables precise adjustment of discharge particle size under load conditions with an accuracy of ±5mm, allowing production requirements to be switched without shutdown. The modular design combined with a split-frame structure reduces core component replacement time to under 2 hours. Maintenance requires no complex tools, enabling even novices to get up to speed quickly.
Energy Conservation and Environmental Protection
The power system has undergone energy-saving calibration, reducing energy consumption by 12%-18% compared to conventional models. Long-term operation significantly lowers unit crushing costs. Equipped with high-efficiency dust suppression and noise reduction devices, combined with a deep cavity design to minimise material rebound and dust generation. Emissions and noise levels comply with environmental standards.
The automatic lubrication system and wear-resistant components reduce maintenance frequency by 30%, cutting annual maintenance costs by 40% and enhancing the equipment's overall return on investment.
