Product Details

Description：

The Zoomlion JS4000 mixing arms—featuring the side-return small arm and large return arm—are masterfully engineered to conquer the toughest concrete mixing challenges. Crafted from ultra-durable, heat-treated chromium-molybdenum alloy steel, these arms combine brute strength with intelligent design to deliver unmatched wear resistance and fatigue performance.The side-return small arm operates with surgical precision, directing material flow toward the mixer’s core to eliminate dead zones and ensure 360° homogenization. Paired with the robust large return arm, which leverages a reinforced, curvature-optimized profile, the system synergistically reduces aggregate impact forces by 30% while maintaining consistent batch quality. Their asymmetrical geometry and hardened surface coatings (up to 62 HRC) slash adhesion risks, even with sticky additives like fly ash or silica fume, ensuring up to 20% longer service life versus conventional designs. Built for mega-scale projects, these arms integrate seamlessly into JS4000 mixers, featuring quick-release bolt slots for tool-free maintenance. Rigorously tested under ISO 9001 standards, Zoomlion’s mixing arms transform reliability into a competitive edge—where every rotation saves time, every mix maximizes ROI, and downtime becomes a relic of the past.

Features and Advantages

Enhanced Mixing Efficiency: Curved surface design optimizes material distribution trajrctories within the mixing drum.

High-Chromium Cast Iron: With an optimized alloy formula, they withstand aggregate impacts and cement slurry abrasion.

Precision Manufacturing: Utilizing lost foam casting technology, critical dimensions are controlled within ±0.5mm tolerance.

OEM-Compatible Fit: Engineered to match Js3000 mixer dimensions for seamless installation.

Extended Lifespan: Dynamic optimization of the alloy formula creates a rational hardness gradient on the mixer arm surface.

Smart Production Ecosystem: End-to-end digital management integrates order tracking, real-time quality control to achieve a closed-loop manufacturing-usage-recycling lifecycle.

Low-Carbon Footprint: Combined with ISO45001-Certified clean production process, carbon footprint per ton of product is reduced by 15%, supporting eco-friendly construction.

Sustainable manufacturing: Employing alloy remelting regeneration technology, over 90% of retired materials are recycled.

Production Line Capabilities

1、Vertical Flaskless Molding Line: Enables high-speed, large-batch production with minimal dimensional variance.

2、Lost Foam Casting: Delivers complex geometries and smooth surfaces for precise fitment.

3、Medium-Frequency Induction Furnace: Ensures uniform melting of high-chromium alloys (Cr content 15-28%).
