Experimental Jaw Crusher for Laboratory Ore Crushing and Sample Preparation

Product Overview

This high-performance laboratory jaw crusher is a specialized instrument for controlled size reduction of hard and brittle materials. Designed for small-batch sample preparation, it crushes input material through a compression motion between a fixed and a moving jaw, producing granular output with exceptional uniformity. The equipment is engineered for use in research institutes, analytical laboratories, and quality control environments where reproducibility is critical.

Ideally suited for processing ores, minerals, and rock samples, the crusher accommodates feed sizes up to 35mm and delivers final particle sizes adjustable from 0.01 to 8mm. Industries such as mining, metallurgy, construction materials, and chemical engineering benefit from its ability to prepare representative samples for subsequent analysis. It handles tough materials like limestone, calcium carbide, shale, basalt, river pebbles, and other stone aggregates with ease, making it a versatile addition to any lab.

This unit is built to rigorous manufacturing standards, employing high-grade wear-resistant steel for the jaw plates and a heavy-duty eccentric shaft. The robust construction ensures minimal wear and long-term stable performance, even under continuous duty cycles. With a compact footprint of 730x510x570mm, it fits neatly on standard lab benches, saving valuable workspace while delivering industrial-grade crushing power.

Key Features

• Adjustable Output Gap: The crushing gap is calibrated via a precision mechanism, enabling continuous adjustment from 0.01 to 8 mm. This fine control produces uniform particle sizes essential for reproducible analytical results, and a clear scale marking allows quick, repeatable settings.
• High-Speed Crushing Action: Jaw oscillation at 560 rpm, powered by a 0.75 kW motor rotating at 1400 rpm, delivers rapid throughput with minimal heat generation. The high-frequency motion ensures efficient fragmentation even with tough materials.
• Premium Wear-Resistant Materials: The jaw plates are cast from high-manganese steel, hardened to withstand abrasive wear from quartz and other hard minerals. This extended durability reduces replacement frequency and ensures consistent performance over thousands of cycles.
• Compact Footprint: With overall dimensions of just 730×510×570 mm, this crusher fits easily on standard workbenches. Its low center of gravity and sturdy base prevent vibration-related issues, making it suitable for sensitive lab environments.
• Easy Maintenance & Cleaning: A hinged housing allows quick opening of the crushing chamber for thorough cleaning and inspection. Jaw plates can be replaced in minutes without specialized tools, minimizing downtime between sample batches.
• Versatile Material Compatibility: Designed for materials with compressive strength up to 320 MPa, it processes everything from soft limestone to hard basalt and ferroalloys. Ideal for multi-user labs handling diverse sample types.
• Efficient Motor Drive: The 0.75 kW single-phase motor (220V) delivers reliable torque while keeping power consumption low. The enclosed, fan-cooled motor design adds to operational safety and longevity.
• Precision Jaw Alignment: The eccentric shaft and bearing assembly are machined to tight tolerances, ensuring uniform jaw movement and a perfectly straight crushing path. This eliminates slippage and uneven wear, improving particle shape consistency.
