Product Overview
This heavy-duty stainless steel crusher is engineered for coarse size reduction in demanding industrial environments. Its powerful 2.2 kW motor and precision-ground tool steel blades efficiently break down hard, fibrous, or bulky materials into uniform granules. The all-stainless construction meets strict hygiene requirements, making it ideal for pharmaceutical, food, and cleanroom operations. By delivering consistent granule sizes, it establishes a reliable foundation for efficient downstream pulverization or material recovery.
As essential pre-processing equipment, the unit prepares materials for fine grinding, recycling, and material reclamation. It excels in laboratory sample preparation, pilot production, and small-scale processing of traditional Chinese medicines, plastic waste, chemical agglomerates, and animal bones. The compact design and flexible voltage options allow easy integration into existing workflows, while the robust build quality ensures stable performance across diverse applications.
The crusher delivers consistent performance even under continuous heavy loads, thanks to a high-strength cast steel crushing chamber and durable blades. Advanced safety mechanisms and straightforward maintenance ensure long-term reliability and minimal production interruptions. Its precision engineering and industry-specific features make it a trusted choice for professionals seeking uncompromising quality.
Key Features
- Premium Stainless Steel Build: All feed-contact parts are manufactured from high-grade stainless steel, preventing rust and contamination. This construction complies with GMP and HACCP standards, essential for pharmaceutical and food processing. An optional upgrade to 304 stainless steel further enhances corrosion resistance for harsh environments.
- Robust Cutting System: Nine moving blades and two fixed blades, crafted from high-quality tool steel, deliver reliable fragmentation. These blades are adjustable and can be reground multiple times, effectively tripling the service life compared to conventional designs. The cutting geometry ensures clean cuts and minimal heat generation.
- Optimized Particle Control: Interchangeable screen meshes (φ5–20 mm) and adjustable blade clearance give precise control over final particle size. This flexibility accommodates a broad range of materials, from fine regrind for injection moulding to coarse chunks for extraction pre-processing.
- Advanced Safety Mechanisms: A travel switch instantly cuts power when the feed hopper is opened, while motor overload protection and a power interlock prevent equipment damage and operator injury. These integrated safeguards exceed standard occupational safety requirements.
- Low-Noise, Low-Vibration Operation: Double-layer acoustic insulation on the crushing chamber and a fully enclosed belt guard minimize noise and vibration. This makes the unit suitable for noise-sensitive labs and production floors without compromising comfort.
- Ease of Maintenance: The separate hopper, chamber, and screen assembly are designed for quick disassembly and cleaning. A large-capacity collection bin reduces the frequency of emptying, keeping batch processing seamless and reducing downtime.
- Uniform Granule Output: Precision-machined blade holders and a step-shear moving blade design distribute cutting forces evenly. The result is a narrow granule size distribution that enhances downstream processing efficiency and product consistency.
- Versatile Material Handling: Capable of crushing fibrous roots, dried herbs, hard bones, engineering plastics, films, and sheets. Custom configurations adapt the machine to specific material characteristics, eliminating the need for multiple specialized crushers.
- Integrated Safety Interlocks: A travel switch de-energizes the motor when the feed hopper is opened, preventing accidental contact with moving blades. Overload protection and a power interlock system safeguard against electrical faults and motor burnout.
- Oversized Collection Bin: The discharge bin holds double the volume of standard 180-class crushers, reducing the need for frequent emptying during bulk processing and enhancing operational efficiency.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Pharmaceutical Preparation | This crusher efficiently processes tough medicinal materials like dried ginseng, astragalus roots, and bundled herbal vines into uniform particles. The adjustable screen and blade gap allow precise sizing to meet the feed requirements of subsequent fine mills. | Preserves bioactive compounds by minimizing heat generation and ensures consistent particle size distribution for repeatable processing. |
| Food Processing | Breaking down fresh or cooked animal bones (chicken, pork, beef) into manageable pieces for stock, pet food, or fertilizer production. The stainless construction maintains sanitary conditions and withstands cleaning regimes. | High crushing capacity reduces manual labor and accelerates production cycles in high-volume food facilities. |
| Plastic Recycling – Rigid Waste | Shredding injection moulding sprues, reject parts, automotive components, and electrical housings into reusable regrind. The robust blades easily handle glass-filled plastics and tough polymers. | Consistent flake size improves feeding in reprocessing extruders and injection machines, reducing waste and material costs. |
| Plastic Recycling – Film & Sheet | Crushing LDPE films, PP sheets, and thin packaging materials using specialized screens and blade gaps. The anti-wrap design prevents material from jamming around the rotor. | Clean, uniform granules enable direct reuse in blown film and thermoforming lines, closing the recycling loop. |
| Chemical Material Pre-processing | Reducing agglomerates, lumps, and off-spec chemical products to a uniform particle size for subsequent fine milling. The corrosion-resistant stainless steel handles mildly aggressive chemicals without contamination. | Ensures safe, contaminant-free size reduction, protecting both the product and the downstream equipment. |
| Botanical and Herbal Extraction | Shredding dried botanicals, roots, barks, and seeds to increase surface area for solvent-based extraction. The gentle crushing action minimizes heat damage to heat-sensitive compounds. | Maximizes extraction efficiency and yield by exposing more material to the solvent while preserving extract quality. |
| Laboratory Sample Preparation | Crushing geological, ceramic, or composite samples to defined sieve fractions for analytical testing. The easy-clean design prevents cross-contamination between sample batches. | Narrow particle distribution ensures representative sampling and accurate QA/QC data, critical for research and quality control. |
| Waste Volume Reduction | Destroying defective products, packaging scrap, and other solid waste to reduce disposal volume and facilitate material recovery. The rugged cutting system and overload protection handle irregular feed without jamming. | Significantly lowers waste disposal costs and supports sustainability initiatives by enabling material reclamation. |
