Key Takeaway: For concrete batching plants seeking unparalleled durability, precision, and efficiency, Haitian Casting’s mixing arm—crafted from ZG310-450 alloy and refined through advanced casting and heat-treatment processes—delivers industry-leading performance and longevity.
Why the Mixing Arm Matters
In a concrete batching plant, the mixing arm works in tandem with blades to ensure thorough, uniform blending of cement, aggregates, and additives. A substandard mixing arm can lead to uneven mixes, premature wear, and costly downtime. Investing in a premium mixing arm is essential for stable plant operation, reduced maintenance, and consistent product quality.
Material Excellence: ZG310-450 Alloy
Haitian Casting’s mixing arm is cast from ZG310-450, a high-chromium iron alloy optimized for wear resistance and impact strength. This material choice offers:
Advanced Manufacturing and Heat Treatment
To achieve optimal microstructure and mechanical properties, the mixing arm undergoes:
Precision Casting: Utilizing Danish DISA vertical molding lines and horizontal molding systems ensures dimensional accuracy (CT8 grade) and consistent wall thickness.
Controlled Heat Treatment: A continuous suspended push-rod furnace provides uniform heating and quenching, followed by tempering to balance hardness and ductility. This process yields:
Yield strength up to 570 MPa
Tensile strength up to 310 MPa
Elongation of 15% for improved toughness and impact resistance.
100% Quality Inspection: Each arm is spectrally analyzed for composition accuracy and undergoes full-size dimensional checks using CMM and laser scanning to guarantee compliance with design tolerances.
Optimized Design for Maintenance and Efficiency
Beyond raw material and processing, Haitian Casting engineers have refined the mixing arm’s geometry to:
Minimize stress concentrations and avoid premature crack initiation.
Facilitate quick replacement and alignment within the mixer to reduce plant downtime.
Ensure uniform flow patterns during mixing, improving batch consistency and reducing cycle times.
Proven Field Performance
Haitian Casting’s mixing arms have been adopted by leading OEMs and end users worldwide, contributing to:
Up to 30% longer service life compared to conventional castings.
Downtime reductions of over 20%, translating into measurable cost savings.
Stable mixing quality under varying load conditions, even in high-output batching plants.
