Jaw Crusher with 400x600mm Feed Opening for Primary Rock Crushing in Mining and Construction

Product Overview

This heavy-duty jaw crusher serves as the backbone of primary crushing stations in mining and aggregate plants. Designed to accept large feed up to 350 mm, it reliably reduces oversize rock to a manageable 50-100 mm product in a single pass, eliminating the need for secondary pre-crushing.

Engineered with a deep symmetrical crushing chamber, the machine optimizes nip angle and stroke frequency for maximum throughput. Its robust welded frame and high-manganese steel jaws withstand abrasive materials and shock loads, delivering years of trouble-free service with minimal downtime.

The unit is particularly valued for its low operational costs. Energy consumption is significantly lower than conventional designs, and the simple mechanical structure—with only a few wearing parts—keeps maintenance budgets under control. Whether in a remote mine or a busy quarry, this crusher provides consistent performance shift after shift.

Key Features

• Deep Crushing Chamber with No Dead Zone: The optimized cavity geometry maximizes material intake and eliminates dead zones, allowing the crusher to handle larger volumes without bridging. This design increases throughput and reduces wear on the jaw plates.
• High Crushing Ratio & Uniform Product: Engineered to deliver a high reduction ratio, this unit produces a uniform and cubical product with minimal slab or elongated particles, enhancing the efficiency of downstream milling or screening equipment.
• Shim-Type Discharge Adjustment: Quick and precise setting of the discharge opening via shim packs, offering a wide adjustment range (50-100 mm) to meet varying output requirements. The shim pack system provides reliable, maintenance-free setting changes without the need for hydraulic components, ensuring consistent gap control over long production runs.
• Reliable Lubrication System: The centralized grease lubrication system automatically distributes lubricant to key bearing points, significantly extending maintenance intervals and preventing premature failure from dry running. Easy access for routine top-ups reduces service time.
• Energy-Efficient Operation: Advanced mechanical design reduces internal friction and electrical losses, achieving 15–30% lower power consumption per ton crushed compared to comparable machines. In complete crushing circuits, energy savings can double, offering a rapid return on investment.
• Low Noise & Dust Emissions: The enclosed structure and optional dust extraction ports minimize environmental impact, meeting occupational health regulations. Special sound-dampening mounts reduce transmitted vibration to foundations.
• Simple and Durable Construction: Constructed from heavy-gauge steel plate with reinforced ribs, this crusher resists fatigue cracking. The reversible jaw plates can be flipped to maximize wear life, and the bolted design allows easy replacement of wear parts.
• Wide Application Range: Suitable for a broad spectrum of materials, from hard granite and basalt to limestone and recycled concrete, making it a versatile asset in any aggregate or mineral processing operation.

Why Choose This Product

• Robust Construction: The frame is fabricated from thick rolled steel plate with stress-relieved welded joints, delivering exceptional rigidity and shock resistance. All critical castings are heat-treated for durability, ensuring this crusher surpasses many competitors in longevity when handling hard, abrasive feed.
• Smart Design: The eccentric shaft is forged from high-quality alloy steel and mounted on oversized spherical roller bearings, which are sealed to exclude contaminants. The toggle plate doubles as a safety device, releasing under overload to protect the crusher from damage.
• Operational Savings: Thanks to the optimized crushing dynamics, the unit requires less power per ton of output. Industry benchmarks show a 15-30% reduction in energy bills, and when coupled with our energy-efficient drives, the savings compound. Additionally, the extended wear life of jaw plates and liners slashes consumable costs.
• Versatile Configurations: Choose between corrugated or plain jaw profiles, and specify optional bolt-on wear plates for the side liners. For dusty operations, integrated water spray nozzles and dust collection hoods can be factory installed to suit specific job site requirements.
• Global Support & Service: Our technical team provides installation guidance, on-site training, and ongoing remote monitoring options. With warehouses strategically located worldwide, critical spare parts are delivered within 48 hours to minimize downtime and keep your operation running smoothly.
