For professional breweries and malt houses, achieving the perfect "grist spectrum"—crushing the endosperm completely while preserving husk integrity for filtration—is the foundation of brewhouse efficiency.
Bellaex addresses this challenge with our heavy-duty Malt Mill Rolls, manufactured from centrifugally cast Chilled Cast Iron to achieve a uniform surface hardness of HS 70–75. This superior metallurgical structure ensures that the fluting profile remains sharp even under high-throughput operations, resisting abrasive wear significantly longer than standard iron rolls.
Beyond standard dry milling, Bellaex stands out with our National Patent for wet Crushing Rolls, featuring specialized corrosion-resistant alloys engineered to withstand acidic steep water and prevent clogging, solving the most common maintenance headaches in modern wet milling systems.
At Bellaex, we control every variable to ensure premium quality:
Centrifugal Composite Casting Unlike static casting, our Malt Mill Rolls are manufactured using advanced centrifugal casting technology. This process creates a dense, defect-free outer working layer of Chilled Cast Iron with a softer, high-strength core. This dual-structure ensures the roll has the extreme surface hardness needed for crushing while maintaining the toughness to resist shaft breakage.
Premium Alloy Composition (LTCrMoNi) We utilize a specialized Low Alloy Chilled Cast Iron (LTCrMoNi) matrix. By strictly controlling the Carbon, Nickel, Chromium, and Molybdenum content, we achieve a uniform surface hardness of HS 70–75. This specific microstructure provides exceptional wear resistance, ensuring your Crushing Rolls maintain their fluting (corrugation) profile significantly longer than standard grey iron rolls.
Precision Fluting & Dynamic Balancing For the brewing industry, geometry is everything. We employ CNC fluting machines to cut precise "Sharp-to-Sharp" or "Sharp-to-Dull" profiles. Furthermore, every roll undergoes G2.5 Dynamic Balancing to ensure vibration-free operation at high rotational speeds, protecting your mill's bearings and ensuring a quiet brewhouse environment.
Patented Wet Milling Technology For our Wet Crushing Rolls, we apply our patented alloy formula (Patent No. ZL200420039645.8) which enhances corrosion resistance against acidic steep water, preventing surface pitting and ensuring long-term hygiene and performance.
Bellaex utilizes advanced centrifugal casting to produce Chilled Cast Iron Rolls with a uniform hardness of HS 70–75. Unlike static cast rolls that may have soft spots, our alloy structure (LTCrMoNi) guarantees consistent wear resistance across the entire barrel length.
The Benefit: Significantly extends the interval between re-fluting maintenance, reducing your brewery's downtime and lowering the total cost of ownership (TCO) per ton of malt processed.
For breweries using wet crushing systems, standard rolls often face corrosion and clogging issues. Bellaex applies our National Patent (ZL200420039645.8) technology to manufacture specialized corrosion-resistant Crushing Rolls. These rolls feature a unique anti-clogging geometric profile designed specifically for steeped malt. The Benefit: Eliminates common "roll blocking" issues in wet mills and prevents rust contamination, ensuring a smooth, hygienic, and continuous mashing process.
We manufacture Malt Mill Rolls to strict OEM dimensional tolerances. Whether you operate a 4-roll, 5-roll, or 6-roll mill from major international brands (e.g., Buhler*, Kunzel*, or others), Bellaex guarantees precision fit for shaft ends and bearing seats. The Benefit: A risk-free "plug-and-play" replacement experience. You get premium roll performance without needing to modify your existing machine or pay premium OEM prices.
