High Capacity Laboratory Jaw Crusher Heavy Duty Primary Sample Preparation Crusher for Hard Brittle Materials

Product Overview

This high-performance laboratory jaw crusher is designed for rapid, heavy-duty size reduction of medium-hard, hard, and brittle materials. Operating on the principle of extreme compressive force between two jaw plates, the equipment breaks down bulk solids into fine particles down to less than 2 mm. Constructed with a robust stainless steel body and engineered for high throughput, this system delivers exceptional crushing performance for both benchtop testing and pilot-scale sample preparation workflows.

Built for demanding research and industrial laboratories, the unit excels in processing geological samples, technical ceramics, raw minerals, concrete, slag, and industrial refractories. Its versatile material configurations and continuous processing capability make it an essential tool for material science, mining analysis, metallurgy, and quality control laboratories requiring rapid particle size reduction without cross-contamination.

Engineered with an IP65 protection rating and full mechanical safety covers, this instrument guarantees long-term operational stability and operator safety under severe continuous workloads. The rigid frame minimizes vibration during high-impact operations, while precision gap adjustment ensures repeatable grain size distribution, batch after batch.

Key Features

• Heavy-Duty Compaction Crushing: Powerful mechanical drive exerts high compressive pressure across a 90x90 mm jaw crushing chamber, rapidly fracturing tough, brittle feed materials up to 90 mm in size.
• Precision Handwheel Gap Adjustment: Features an intuitive handwheel mechanism paired with an easy-to-read analog scale, allowing operators to seamlessly adjust the jaw clearance from 0 to 30 mm for precise product sizing.
• Contamination-Free Material Choice: Offers interchangeable jaw and friction plates in Tungsten Carbide, Zirconia, Stainless Steel, and High-Manganese Steel, ensuring complete compatibility with iron-sensitive or highly abrasive samples.
• High-Throughput Continuous Operation: Engineered to process up to 300 kg/h, making it suitable for both rapid analytical batch crushing and continuous pilot plant sample processing.
• Modular Demountable Jaw Assembly: Quick-release fixed jaw components and removable wear plates allow fast, tool-free access for thorough cleaning, preventing sample carryover between batches.
• Industrial IP65 Sealed Design: The main body and electrical enclosure feature an IP65 dust and moisture protection rating, preventing abrasive fine dust from penetrating internal mechanical components.
• Ergonomic Flip-Top Feed Hopper: Equipped with a wide-mouth hinged feed funnel for safe and easy loading of bulky solids while preventing material splashback during operation.
• Integrated Safety Protection: Fully enclosed drive belt pulley covers and heavy-duty motor shields protect lab personnel from moving parts during continuous high-load crushing cycles.
• Mobile Support Stand: Comes integrated with a heavy-duty steel mobile cart measuring 329x560x490 mm and smooth-rolling lockable omnidirectional castors for effortless relocation across laboratory environments.
