150×125mm Laboratory Jaw Crusher for Medium and Fine Crushing of Brittle Materials

Product Overview

This laboratory jaw crusher is a robust, high-reduction machine designed for efficient primary and secondary crushing of hard, brittle materials. By employing a curved jaw motion that combines both crushing and attrition, it quickly reduces large feed chunks to uniform fine particles, making it an essential tool for sample preparation workflows.

Ideal for sample preparation in mining, metallurgy, geology, coal, and cement labs, the unit processes a wide variety of materials including ores, rocks, slag, coal, coke, and ceramics. Its ability to handle up to 150 MPa compressive strength makes it versatile across many industries, from exploration to quality control.

Engineered for durability, the crusher features a heavy steel frame, premium wear-resistant jaw plates, and a simple mechanical design that ensures years of trouble-free operation. Minimal moving parts reduce maintenance needs while delivering consistent output size through a precisely adjustable discharge gap. Whether operating in a busy central lab or a remote field station, this system delivers dependable performance day in and day out.

Key Features

• High-Efficiency Crushing Action: The curved jaw profile generates a powerful, progressive crushing force that rapidly breaks down feed material. This results in a high reduction ratio and a narrow particle size distribution, ideal for subsequent fine grinding or direct analysis. The optimized crushing chamber geometry minimizes wear and maximizes throughput.
• Durable Wear Parts: Jaw plates are cast from high-manganese steel, which work-hardens under impact to resist abrasion and extend service life. The reversible and replaceable design maximizes uptime and reduces consumable costs. Special alloy plates are available for ultra-abrasive or high-purity applications.
• Precision Gap Adjustment System: A hand-wheel operated wedge mechanism allows quick, repeatable setting of the discharge opening. Operators can easily fine-tune output size from 25 mm down to finer grades without disassembling components. This ensures consistent particle size control across multiple processing runs.
• Heavy-Duty Construction: The all-steel welded frame eliminates misalignment and absorbs vibration. Stress-relieved and machined mounting surfaces ensure long-term geometric accuracy and smooth operation under full load. Sealed, grease-lubricated bearings protect against dust ingress, further enhancing reliability.
• High Throughput Capacity: With a throat size of 125×150 mm and a throughput of up to 1.2 tons per hour, this crusher efficiently handles batch and continuous processing, reducing turnaround times in high-volume labs. Even with large feed sizes under 100 mm, it maintains steady output without clogging.
• Low Maintenance, High Uptime: Grease-lubricated bearings and a simple toggle mechanism require only periodic inspection. Jaw plate replacement can be done in minutes, keeping the unit production-ready. The absence of complex hydraulics or electronics reduces potential failure points.
• Versatile Material Compatibility: Beyond minerals, it crushes slags, cokes, glass, ceramics, and similar brittle materials with compressive strengths up to 150 MPa. This flexibility makes it a single solution for labs handling multiple sample types. Custom jaw profiles can further tailor performance.
• Enhanced Safety Features: A fully enclosed crushing chamber with a dust extraction flange minimizes environmental exposure. Safety interlocks and an emergency stop button protect operators, meeting CE and OSHA guidelines. The compact footprint also reduces the risk of accidental contact during operation.
