Manual-Style Hammer Crushers
Precision crushing system for high-purity ferroalloy preservation.
Product Overview
Our Manual-Style Hammer Crusher is engineered for high-purity ferroalloy processing, delivering precise particle size control while minimizing contamination risks. Designed for small-to-medium batch operations, this crusher combines manual adjustability with robust construction to preserve material integrity in applications demanding strict purity standards. Ideal for laboratory testing, specialty alloy production, and recycling of high-value ferroalloys, it ensures minimal oxidation and metal cross-contamination during crushing.Key Applications
- Metallurgical Research: Precise preparation of ferroalloy samples (e.g., ferrochromium, ferromanganese) for composition analysis.
- Specialty Alloy Manufacturing: Crushing high-purity ferroalloys (≥99.5%) for additive manufacturing or precision casting.
- Recycling: Reclaiming ferroalloy scraps from aerospace or automotive components without introducing impurities.
Design & Performance Features
1. Contamination-Free Crushing
- Material Construction:
- Crushing Chamber: Stainless steel (SS304/316) with electropolished surfaces to prevent adhesion and oxidation.
- Hammers & Grids: Tungsten carbide or ceramic-coated components for wear resistance and zero metallic leaching.
- Sealed Operation: Nitrogen-purge compatibility (optional) to suppress oxidation during processing.
2. Manual Precision Control
- Adjustable Output: Particle size range 0.5–20 mm, fine-tuned via manual gap adjustment of the crushing grid (resolution: ±0.1 mm).
- Batch Capacity: 2–50 kg per cycle (model-dependent), optimized for low-volume, high-value materials.
- Low Heat Generation: Passive cooling design with heat-dissipating fins to prevent thermal degradation of alloys.
3. Ergonomic & Safe Operation
- Manual Flywheel System: Reduces dust generation and eliminates reliance on electric motors, minimizing spark risks.
- Safety Lock: Interlocking cover mechanism halts operation when the chamber is opened.
- Tool-Free Maintenance: Quick-release hammer assembly for cleaning or component replacement.

- Surface Finish: Ra ≤ 0.8 µm (mirror polish optional) to meet ISO 21920-1 surface roughness standards.
Customization Options
- Purge Systems: Integrated nitrogen/argon gas ports for inert atmosphere processing.
- Modular Grids: Interchangeable grids with diamond-coated edges for ultra-fine crushing (≤0.2 mm).
- Sample Collection: Vacuum-sealed discharge trays for direct packaging under controlled environments.
Target Industries
- Advanced Metallurgy: Production of high-purity ferroalloys for semiconductor or nuclear industries.
- Research Institutions: Universities and R&D centers analyzing alloy microstructure and phase composition.
- Recycling Facilities: Recovery of cobalt/nickel-based superalloys from turbine blades or medical devices.
Competitive Advantages
- Purity Guarantee: Manual operation eliminates lubricant contamination risks associated with hydraulic/electric systems.
- Flexibility: Adjustable parameters cater to brittle ferroalloys (e.g., ferroboron) and ductile alloys (e.g., ferronickel).
- Durability: Tungsten carbide hammers sustain >10,000 cycles on Mohs 8.0 materials without significant wear.
