Laboratory Benchtop Jaw Crusher for Hard Brittle Materials Primary Size Reduction and Sample Preparation

Product Overview

This benchtop laboratory jaw crusher represents a pinnacle in primary size reduction technology, specifically engineered for the rapid processing of hard, brittle, and tough materials. Designed to bridge the gap between heavy industrial crushing and delicate laboratory analysis, this system provides a robust solution for preliminary comminution before fine grinding. The core value proposition lies in its ability to handle feed sizes up to 40mm while delivering an exceptionally fine output for a jaw-based system, reaching a d90 of less than 0.5mm. This makes the equipment an indispensable tool for material scientists and quality control technicians who require consistent, reproducible results in sample preparation.

Primarily utilized in mining, metallurgy, geology, and the chemical industry, this unit excels in preparing a diverse range of materials, including ores, coke, ceramics, and high-performance alloys. Its desktop-oriented design allows for seamless integration into existing laboratory environments without the need for extensive floor space or specialized structural reinforcement. By providing a controlled environment for initial size reduction, the equipment protects downstream analytical instruments from excessive wear and ensures that subsequent fine-milling stages are more efficient and less time-consuming.

Engineering excellence is evident in every facet of this unit, from the heavy-duty motor to the precision-machined jaw plates. Built to withstand the rigors of demanding industrial research and high-throughput testing facilities, the equipment offers unmatched reliability. The construction prioritizes durability and operational consistency, ensuring that performance does not degrade even when processing highly abrasive materials like silicon carbide or basalt. Users can have full confidence in the system's ability to maintain tight tolerances and provide a clean, uncontaminated sample every time, supporting the integrity of the entire analytical workflow.

Key Features

• Precision Zero Point Adjustment: This advanced mechanism allows operators to compensate for natural jaw plate wear over time, ensuring the gap setting remains accurate. By adjusting the zero point, the equipment maintains a consistent final fineness throughout its service life, preventing the drift in particle size distribution that often plagues lesser systems.
• High-Throughput Oval Movement Dynamics: The crushing chamber utilizes a sophisticated bent axle design that drives the moving jaw in an oval trajectory. This movement not only extrudes the material with massive force but also facilitates a continuous downward flow under gravity, significantly increasing throughput and preventing material bridging or clogging in the chamber.
• Versatile Material Compatibility: To prevent cross-contamination and address specific hardness requirements, the equipment can be fitted with jaw plates in multiple materials, including Manganese steel, Stainless steel, Tungsten carbide, Zirconium oxide, and heavy-metal-free steel. This versatility allows the system to be used in everything from standard metallurgical testing to high-purity pharmaceutical or electronic ceramic research.
• Optimized Benchtop Ergonomics: Unlike bulky floor-standing units, this system is specifically designed for desktop operation. Its compact footprint does not sacrifice power, offering a 1.1KW rated performance that handles the toughest samples while remaining accessible and easy to install on standard laboratory workbenches.
• Anti-Splash Safety Hopper: The feed inlet features an intelligently designed anti-splash hopper that prevents material flyback during the crushing process. This design prioritizes operator safety and ensures 100% sample recovery, which is critical when working with expensive or limited-quantity raw materials.
• Superior Final Fineness: While most jaw crushers are limited to coarse processing, this unit achieves a d90 of less than 0.5 mm. This high degree of size reduction often eliminates the need for secondary intermediate crushing steps, streamlining the laboratory workflow and reducing the total time from raw sample to analysis.
• Ease of Maintenance and Cleaning: The crushing chamber is designed for rapid access, allowing for thorough cleaning between batches. This feature is essential for preventing cross-batch contamination in multi-user facilities or when switching between different mineralogical or chemical samples.
• Robust Adjustable Gap Settings: The gap between the jaw plates can be adjusted from 0 to 11mm, providing the operator with complete control over the reduction ratio. This flexibility makes the equipment suitable for a wide variety of initial feed sizes and target output requirements.
