SICOMA MAO Series Concrete Mixer Liner - Heavy-Duty Wear Protection Solution

Engineered for the robust SICOMA MAO series of double-shaft forced concrete mixers, this heavy-duty liner is crafted to meet the extreme demands of high-volume, continuous production environments. The MAO series is recognized as the standard model within SICOMA's lineup, designed for stationary plants with capacities ranging from 1.5 to 6.0 cubic meters, serving critical projects from commercial buildings to major infrastructure. Our liner is manufactured to be a direct, high-performance replacement, ensuring your MAO mixer—whether it's an MAO 2250/1500, MAO 3000/2000, or larger models up to MAO 9000/6000—maintains peak operational efficiency and longevity.

Superiority begins with material science. Produced in our ISO 9001-certified foundry, each liner is cast using precision lost-foam and vertical flaskless molding processes. This advanced methodology achieves exceptional material density and purity, creating a structurally sound component free from defects that could become failure points. The alloy is meticulously refined in medium-frequency induction furnaces, resulting in an optimized high-chromium composition. This delivers a proven balance of a high surface hardness (58-65 HRC) for abrasion resistance and superior impact toughness (≥8.5 J/cm²) to withstand the relentless force of aggregates up to 80mm in size. The resulting metallographic structure, rich in hard carbides within a tough matrix, is independently verified to extend service life significantly, reliably protecting the mixer drum through over 350,000 cubic meters of concrete output.

Beyond material excellence, this liner is part of a complete protection system. Its precise geometry and CNC-machined fit ensure seamless integration with the MAO mixer's drum, preserving the integrity of the factory-designed mixing action and flow. This compatibility is crucial for supporting the mixer's advanced features, such as its multi-seal shaft end protection and monitoring systems, which are key to preventing leakage and ensuring reliable operation. By choosing our liner, you invest in more than a spare part; you secure a certified, durable solution that minimizes unplanned downtime, reduces long-term operating costs, and safeguards the productivity of your entire concrete batching plant.

• • Advanced Chromium Alloy: High-chromium composition with molybdenum/vanadium additives ensures 57-65 HRC hardness and superior abrasion resistance.

  • Engineered for MAO Series: Precision-designed as a direct replacement for SICOMA MAO standard series mixers (1.5m³ - 6.0m³ capacity), ensuring perfect fit and performance.
  • Optimized Stress Resistance: Manufacturing via lost-foam casting and vertical flaskless molding achieves >99.8% density, eliminating defects and providing a tensile strength >480 N/mm² to withstand high-impact loads from large aggregates.
