Product Overview
This versatile jaw crusher represents a robust dual-use solution designed for both precision laboratory sample preparation and demanding small-scale industrial applications. Engineered to perform reliable coarse, medium, and fine size reduction, the equipment effectively processes a wide variety of rocks, mineral ores, coal, coal gangue, coke, limestone, and iron pyrite. Its versatile design fills the operational gap between light-duty laboratory grinding tools and heavy industrial mining machinery.
Built to withstand rigorous operational environments, this system features a heavy-duty structural frame and high-torque mechanical drive that effortlessly processes raw feed materials up to 125 mm in diameter. The crushing chamber utilizes an optimized motion profile that provides rapid material reduction down to an adjustable discharge range of 8 to 40 mm, delivering superior efficiency across diverse material hardness levels.
Operational reliability and user safety are engineered directly into the unit. Featuring a fully sealed enclosure option for laboratory environments and heavy cast structural components for pilot plant duty, the equipment minimizes ambient dust emissions while ensuring long-term mechanical stability. It handles raw minerals with compressive strengths up to 320 MPa in standard crushing duties and up to 100 MPa in sealed analytical testing environments.
Key Features
- Curved Squeeze Compression Mechanism: Incorporates a heavy-duty eccentric shaft assembly that delivers a continuous curved squeezing action, maximizing impact energy transfer to rapidly break down hard minerals with minimal material recirculation.
- Adjustable Discharge Granularity: Features a precision mechanical gap adjustment system, allowing operators to easily tune the output particle size between 8 mm and 40 mm to meet exact downstream grinding and analytical testing requirements.
- High-Torque 5.5 kW Motor Drive: Equipped with a robust 380V three-phase electric motor that provides substantial mechanical torque, ensuring continuous, jam-free operation even when processing dense, high-strength mineral feed specimens.
- Sealed Dust-Containment Architecture: Designed with an enclosed crushing chamber that traps fine airborne particulate matter, preventing laboratory cross-contamination and maintaining compliance with workplace health and safety standards.
- High-Strength Wear-Resistant Jaw Plates: Fitted with premium alloy jaw liners specifically engineered to resist extreme abrasion and shock impact, dramatically extending component service life when crushing materials up to 320 MPa compressive strength.
- Dual Industrial and Laboratory Versatility: Purpose-built to transition seamlessly between high-precision quality control laboratories and continuous pilot plant production lines, achieving processing capacities from 1.5 to 4.0 tons per hour.
- Heavy-Duty Cast Structural Frame: Built upon a massive frame weighing 615 kg, providing substantial inertia and vibration damping to maintain structural alignment and operational smoothness under severe mechanical loads.
- Optimized Feed Throat Design: Features a wide 150 x 250 mm intake opening equipped with directional baffle protection to prevent material ejecta and ensure stable, high-volume gravity feeding.
