blog About ANDRITZ Enhances Industrial Separation with Peeler Centrifuges

As global manufacturing advances toward high-quality development and lean production, pillar industries such as chemicals, food, pharmaceuticals, and new energy mineral processing face unprecedented challenges: How to ensure high-purity product quality while achieving exponential capacity growth? How to balance long-term equipment operation with maintenance costs when handling complex materials? Addressing these core challenges, ANDRITZ Separation, a leader in industrial separation technology, presents a compelling solution—the Krauss-Maffei HZ series horizontal peeler centrifuges.

As a benchmark product in industrial filtration, the HZ series is not merely an executor of separation processes but a strategic tool for production optimization. Through profound fluid dynamics research and modular engineering design, the HZ series is redefining the standards of "efficient separation" worldwide.

In traditional centrifugal separation, filtration driving force is often limited by centrifugal force itself, creating bottlenecks when processing fine particles or high-viscosity slurries. The breakthrough of the HZ series lies in its patented "siphon drum" technology.

The introduction of siphon effect fundamentally changes the operational logic of traditional filtration centrifuges. While conventional equipment relies solely on centrifugal force to push liquid through the filter cake, the HZ series creates a controlled vacuum siphon environment beneath the filter cloth, generating a significant pressure differential. This not only enhances filtration driving force but achieves a qualitative leap in filtration rates. Field tests show that siphon technology can increase filtration capacity by 30% to 50% under identical material conditions while significantly reducing residual moisture in filter cakes.

More ingeniously, the siphon system enables "wet feeding." During initial material entry, it forms a uniform liquid pool, cushioning direct impact on the filter cloth. This "gentle feeding" approach protects filter cloth integrity, reduces replacement frequency, and ensures uniform cake structure—laying the foundation for efficient washing and dehydration.

In fine chemicals and pharmaceuticals, product purity directly determines market competitiveness. The HZ series prioritizes "precision control" in its design.

Through a highly integrated automation system, the equipment enables millisecond-level adjustments of filtration rates, wash liquid flow, duration, and drum speed. This deep control capability allows customized separation curves for diverse materials. For instance, in active pharmaceutical ingredient (API) production, the multi-stage washing function thoroughly removes impurities, ensuring product purity exceeds industry standards.

Additionally, the unique backflush function addresses residual cake issues. During continuous operation, filter cloth clogging can degrade performance. The HZ series' automated backflush program uses high-pressure fluid to clean the cloth after each batch, maintaining optimal conditions and consistent product quality.

To address modern industrial volatility, the HZ series adopts exceptional modular design principles.

Users can switch between traditional filtration drums and high-efficiency siphon drums based on needs. The cantilevered drum support simplifies mechanical structure, reduces wear points, and ensures dynamic balance stability during high-speed operation.

Maintenance is optimized with a full-access shell door, allowing easy access to core components. Modular layout minimizes downtime—critical for reducing operational costs (OPEX) and enhancing lifecycle value.

For varying cake properties, the system offers pneumatic or hydraulic cleaning options, ensuring complete residue removal for any material type.

• Food Industry: Ensures product safety and shelf life in starch, sweeteners, and additives production through hygienic design and dehydration efficiency.
• Chemical Sector: Handles corrosive, volatile, or high-purity chemicals with specialized materials and seals, boosting product value.
• New Energy Minerals: Excels in lithium salt crystallization and battery material refining, providing critical quality support for the battery supply chain.

The Krauss-Maffei HZ series represents more than precision equipment—it embodies ANDRITZ Separation's technical expertise and industrial vision. By mastering fluid dynamics, refining process control, and leveraging modularity, the HZ series delivers comprehensive solutions for complex workflows.

Choosing the HZ series means investing in reliability, flexibility, and future-ready technology. It empowers companies to optimize processes, enhance product value, and navigate Industry 4.0 with confidence. As ANDRITZ Separation advances in digitalization, the HZ series will integrate IoT and big data, driving smarter, more efficient industrial transformations.
