150x250mm Custom Laboratory Jaw Crusher for Coal Ore Mineral Crushing

Product Overview

This laboratory jaw crusher is a robust, customizable solution engineered for efficient medium to fine crushing of coal, ores, minerals, and other solid materials. Its core value lies in providing reliable sample preparation with fully adjustable output granulometry, enabling consistent and repeatable analytical results across diverse testing protocols. The unit integrates a reinforced base frame and sloped discharge chute, which are key differentiators that enhance operational stability and material handling convenience.

Primarily deployed in material science laboratories, mining and geological survey institutions, coal quality testing centers, and ceramic and building material research, this system excels at processing raw samples from large chunks down to granular sizes suitable for further testing or processing. It is the go-to choice for laboratories that demand precision, versatility, and robust performance in high-throughput environments.

Built with a heavy-duty frame and high-grade components, this equipment ensures long-term structural integrity and consistent performance even under demanding continuous operation. The customizable features, including optional jaw plate materials and motor power variations, make it a wise investment for laboratories requiring tailored sample preparation solutions that adapt to evolving analytical needs.

Key Features

• Custom Reinforced Base Frame: The specially designed base frame significantly enhances structural stability and load-bearing capacity, minimizing vibration and extending the equipment's service life during intensive crushing operations. This foundation upgrade is critical for labs that process large volumes of dense or abrasive materials daily.
• Sloped Discharge Chute: Precision-engineered with an adjustable slope angle and length, this chute promotes smooth, obstruction-free material flow after crushing. It reduces the need for manual intervention to clear blockages and virtually eliminates cross-contamination between sample batches, saving time and ensuring purity.
• Adjustable Jaw Gap: The gap between the fixed and movable jaws can be easily calibrated to achieve a wide range of output particle sizes, from fine powders (<8 mm on smaller models) to granular pieces (<45 mm on this unit). This flexibility allows one crusher to serve multiple analytical standards, from coal proximate analysis to mineral liberation studies.
• High-Reduction Curved Crushing Mechanism: Utilizing a curved extrusion movement, the mechanism delivers an exceptional crushing ratio while generating a controlled amount of fines. This preserves the integrity of the material for subsequent analysis and ensures uniform particle size distribution, which is essential for reproducible results.
• Premium Wear-Resistant Jaw Plates: Available in high manganese steel or alloy steel as custom options, these plates offer outstanding durability against hard and abrasive substances such as quartz, pyrite, and clinker. The right material selection can dramatically extend service intervals and reduce contamination risks.
• Industrial-Grade Motor Options: The unit supports customizable motor power ratings (standard 5.5 kW for the 150x250 model) to match specific material hardness and throughput requirements. This ensures optimal energy efficiency and prevents motor overload, even when processing tough ores at maximum capacity.
• Dust-Containment Housing (Optional): An available sealed housing effectively contains airborne dust, maintaining a clean laboratory environment and protecting operator health. This option is especially valuable when crushing friable materials like coal or gypsum that generate significant dust.
• Simple Operation and Maintenance: Designed with ergonomics in mind, the crusher features easy front-loading of samples, tool-free access for cleaning between batches, and straightforward maintenance points. These design elements minimize downtime and make it suitable for multi-user laboratory settings.
