Laboratory Sealed Hammer Blade Crusher Divider for High Hardness Sample Preparation

Product Overview

This hammer blade crushing and dividing system is a specialized sample preparation unit designed for high-hardness materials in laboratory and pilot-scale operations. It combines efficient hammer impact and shear cutting to reduce tough samples to uniform particle sizes while integrating a built-in division mechanism for representative subsampling. The sealed construction minimizes dust, making it suitable for environmentally sensitive analytical workflows.

The equipment is ideally deployed in coal testing, coke evaluation, mineral assay, and geological exploration laboratories. It processes materials with compressive strength up to 200 MPa, including iron ore, bauxite, gold ore, and similar hard substrates. Its robust all-steel crushing chamber and wear-resistant blade set ensure consistent output over thousands of cycles.

Engineered for 24/7 reliability, this unit features a rigid transmission system with protective guards and a low-noise design. The full-width hammer blades prevent material accumulation and bridging, while the caster-mounted frame allows easy repositioning within crowded lab spaces. Every component is selected for longevity in heavy-duty sample preparation.

Key Features

• Dual Crushing Mechanism: This system incorporates both high-speed hammer impact and precision shear cutting, enabling it to handle materials that are traditionally difficult to crush, such as high-hardness ores and fibrous agricultural samples. The combined action produces a more uniform particle shape with a higher proportion of cubical fragments compared to jaw crushers, which is beneficial for subsequent analysis.
• Sealed Dust-Free Operation: The fully enclosed crushing chamber and discharge port protect operators from airborne particulates, meeting occupational health and environmental requirements. This design also prevents sample cross-contamination and minimizes cleaning frequency between batches.
• All-Steel Chamber with Replaceable Liners: The crushing cavity is fabricated from heavy-gauge steel with bolt-on wear plates at vulnerable areas, ensuring extended service life and easy maintenance. Liners can be quickly replaced when worn, reducing downtime and operating costs.
• Wide Material Compatibility: It accommodates materials with moisture content up to 10% without clogging or moisture loss, making it suitable for coal or wet minerals. The hammer blades' symmetrical arrangement and slow-speed shear action handle both brittle and ductile materials effectively.
• Uniform Granularity Control: Adjustable discharge screens deliver consistent particle size distributions ranging from 3 to 18 mm, critical for representative analytical samples. The output is predominantly rounded granules with minimal fines, preserving sample integrity for further testing.
• Onboard Sample Division: An integrated rotary divider provides adjustable split ratios (1/2 to 1/8) for producing proportional subsamples without additional equipment. This eliminates the need for a separate dividing step, streamlining the sample preparation process.
• Robust Drive Train: Hardened gear transmission with overload protection and full guarding ensures safe, reliable operation under continuous duty cycles. The direct-drive design eliminates belt slippage and reduces maintenance requirements.
• Low Noise and Mobility: Vibration-dampening mounts and precision balancing minimize operating noise, creating a more comfortable work environment. Swivel casters and a compact footprint enable easy repositioning or storage when not in use.

Applications

Technical Specifications

Both models incorporate the same dual hammer-shear crushing principle and sealed architecture, differing primarily in feed opening size and throughput capacity to suit varying laboratory scales.
