Small Laboratory Jaw Crusher 150x200mm Feed Opening for Sample Preparation and Medium Fine Crushing

Product Overview

This laboratory jaw crusher is a precision-engineered system for medium and fine crushing of hard, brittle materials in sample preparation. Its working principle is based on a bending extrusion action, where material is crushed between a stationary and a moving jaw plate, producing uniform particles with minimal fine dust. Designed for materials with compressive strength up to 150 MPa, this unit is an essential tool for labs needing reliable size reduction.

Typical applications span mining, geology, metallurgy, ceramics, glass, and construction materials. Whether processing ore samples for mineralogical analysis, ceramic raw materials for batch testing, or geological specimens for field surveys, this crusher delivers consistent performance. Its ability to handle feed particles up to 120 mm and reduce them to adjustable sizes below 30 mm makes it versatile for various analytical methods.

Built for durability, the crusher features high manganese steel jaw plates that withstand abrasive wear, ensuring longevity in demanding lab environments. The 4 kW motor provides ample power for continuous operation, and the compact frame integrates easily into benchtop or floor-standing setups. With safety guards and simple controls, operators can rely on this system for safe, efficient, and repeatable results. The discharge port is easily adjusted via a screw mechanism, providing reproducible settings for different material types.

Key Features

The crusher incorporates numerous engineering enhancements to deliver unmatched performance:

• High Manganese Steel Jaw Plates: Fabricated from high-grade austenitic manganese steel, these jaw plates exhibit outstanding wear resistance due to work hardening under impact. This characteristic prolongs service intervals and reduces replacement frequency, lowering operational costs in high-volume labs.
• Adjustable Output Particle Size: A screw mechanism allows precise adjustment of the discharge opening, enabling output sizes from coarse to under 30 mm. This flexibility ensures the product adapts to different downstream sieving or pulverizing steps, and the setting can be locked for batch consistency.
• Proven Crushing Mechanism: The bending extrusion action generates less dust and overheating compared to impact-based crushers, preserving sample integrity for moisture-sensitive or volatile materials. This low-friction process also contributes to lower energy consumption.
• Optimized Throughput: With a capacity range of 0.5 to 2.0 tons per hour, this unit efficiently processes batch samples while maintaining particle size uniformity. The robust design handles continuous throughput without degradation in performance.
• Robust Construction: The heavy-duty frame and precision-machined components minimize vibration and noise, contributing to a stable work environment. All parts are designed for easy cleaning and minimal maintenance, with corrosion-resistant coatings for longevity.
• Integrated Safety Features: Equipped with emergency stop, electrical overload protection, and protective covers, the crusher meets lab safety standards and protects both operator and equipment. The feed hopper is designed to prevent material splash.
• Easy Operation: Intuitive start/stop controls and clear adjustment guidelines make this unit user-friendly, even for technicians with minimal training. Quick-release access panels simplify inspection and cleaning, and the lubrication points are easily accessible.
• Customization Ready: Options include alternative jaw materials (e.g., tungsten carbide for extra hardness), voltage configurations, and custom paint finishes to match lab aesthetics or specific application needs.
• Low Maintenance Design: The simple jaw replacement procedure reduces downtime significantly. Regular inspection takes only minutes, and all critical components are designed for long maintenance intervals.
• Versatile Application Range: From hard rock to ceramic materials, this crusher adapts to a wide range of sample types, making it a universal tool in the preparation lab. Changing between materials requires only minimal cleaning to prevent cross-contamination.
