Precision Engineering & High-Performance
High-performance Screen Classifying Cutter offers a unique dual-action mechanism for superior size reduction. By combining the precision of a knife cutter with the high-speed impact of a hammer mill, this system provides unmatched versatility for processing friable, fibrous, and semi-hard materials.
Designed for high-capacity throughput, the cutter features a solid-mass rotor with a staggered helical array. This design ensures material is distributed evenly across the entire screen area, resulting in uniform particle sizes and minimal fines. With adjustable speeds ranging from 30 to 3600 RPM, you have complete control over the final output, down to 20 mesh or smaller.
Key Technical Features
- Uniform Particle Quality: The precision-machined clearance between the rotor and bed knives ensures a consistent cut, resulting in uniform particles and significantly fewer “fines” (dust). Achieve precise particle size distribution with significantly fewer fines and low heat buildup.
- Extreme Versatility: One machine handles everything from soft fibers to hard minerals by simply adjusting the RPM. Get the benefits of two machines in one—shear thin fibers at low speeds or impact-crush hard materials at high speeds.
- Versatile Sizing: Interchangeable bed screens available in various shapes and sizes (from 0.79 mm to 152 mm).
- Scalable Solutions: Available in various sizes, from laboratory-scale mini cutters to ultra-high-capacity industrial models. Whether you need a laboratory-scale Mini Cutter for R&D or an ultra-high-capacity Magnum Cutter for 24/7 industrial production, it has the right frame size for your facility.
- Interconnected Helical Rotor: Optimizes cutting efficiency and minimizes heat generation.
- Easy Maintenance & Lower Operating Costs: Helical cutting patterns and reversible knives ensure uniform wear and extended maintenance intervals. The unique helical design ensures uniform wear across all cutter tips and bed knives, extending the intervals between maintenance cycles. Hardened knives can be flipped and resharpened to double their service life. Replaceable tungsten carbide cutter tips secured for rapid changeover.
- Clean Operation: Equipped with dust-prevention baffles and options for pneumatic discharge to keep your facility clean.
- Durable Construction: Heavy-duty carbon steel or food-grade stainless steel finishes to meet industrial and sanitary standards.
- Custom Configurations: Offer various options including sound-deadening enclosures, air-purged seals for hazardous environments, and specialized transitions for pneumatic pick-up systems.
Advanced Engineering & Operational Logic
Utilizes a solid-mass rotor equipped with interconnected, staggered cutter tips:
- Helical Cutting Action: The blades are arranged in a staggered helical array, ensuring that material is distributed evenly across the entire width of the chamber. This eliminates “dead zones” and utilizes 100% of the screen area.
- Variable Speed Versatility: With an adjustable range from 30 to 3,600 RPM, you can fine-tune the processing speed to match your material’s specific characteristics, ensuring maximum throughput with minimal heat generation.
- Superior Grain Control: Materials are continuously processed until they pass through the bed screen. We offer round perforations (0.79 to 51 mm) and square perforations (up to 152 mm) to reach sizes as fine as 20 mesh.
Built for Heavy-Duty Industrial Use
- Extended Component Life: Our hardened bed knives are reversible; simply flip the knife to utilize a fresh cutting edge, doubling the service life before resharpening is required.
- Replaceable Inserts: Standard units come with Tungsten Carbide tips for maximum abrasion resistance. Optional tool steel or stainless steel inserts are available for specialized applications.
- Safe & Clean Feeding: The infeed chute is equipped with rubber baffles to prevent material “flash-back” and dusting, maintaining a clean and safe working environment.
- Application Specific Finishes: Available in heavy-duty carbon steel for industrial scrap or high-grade stainless steel for sanitary food and pharmaceutical applications.
Applications
Ideal for a vast range of materials, including:
- Chemicals & Pharmaceuticals: Detergents, filter cakes, and medical waste.
- Food & Spices: Herbs, grains, sugar cane, and bulk food products.
- Industrial Scrap: Plastics, fiberglass, rubber, and wood.
- Minerals: Clays, coal, and gypsum.
Why Choose Screen Classifying Cutters?
This cutter stands out by offering a unique dual-action capability, functioning as both a precision knife cutter and a high-speed impact mill. This allows you to process everything from delicate fibers to hard minerals with a single machine. By adjusting the variable RPM and selecting from a wide range of interchangeable screens, you gain absolute control over your final particle size, ensuring a uniform output down to 20 mesh with significantly fewer “fines” and minimal heat buildup.
Engineered for longevity, this system features a staggered helical rotor design that ensures even wear across all cutting surfaces, drastically extending the time between maintenance cycles. With reversible bed knives that double the service life and easily replaceable tungsten carbide inserts, you can maintain peak performance with minimal downtime. Whether you require a laboratory-size unit or a high-capacity industrial model, this cutter provides a robust, cost-effective solution tailored to the most demanding sanitary or industrial environments.
SCC™ Screen Classifying Cutter
Delivers high-capacity size reduction for hard, semi-hard, and fibrous materials. It is specifically engineered to produce precise, controlled particle sizes with maximum efficiency and rapid throughput.
Advanced Helical Rotor Design
Depending on the RPM, the staggered helical cutter tips continuously shear or shatter oversized materials against dual stationary bed knives, ensuring high precision with minimal dust or heat.
Precision Screening
Bed screens feature round perforations from 0.79 to 51 mm (1/32 to 2 in.) and square perforations from 25 to 152 mm (1 to 6 in.), ensuring consistently uniform particle sizes.
Seamless Integration
