Product Description

Premium Cast Iron Wear Parts for Asphalt Plants

Engineered for 160°C+ Thermal Cycling & Aggregate Abrasion
Patented High-Chromium Alloys Redefine Mixing Durability

Specification

Applications:

Production of Hot Mix Asphalt (HMA) for Road Construction: The primary application is producing precisely proportioned, heated mixtures of aggregate, bitumen binder, and sometimes additives.
Airport Runway and Taxiway Paving: Asphalt plants produce specialized, high-stability, and durable mixes designed to withstand the immense static and dynamic loads imposed by aircraft.
Industrial and Commercial Surfacing: These plants supply asphalt mixes used for paving large industrial yards, commercial parking lots, distribution centers, port terminals, racetracks, and other heavy-duty pavements.
Production of Warm Mix Asphalt (WMA) and Cold Mix Asphalt: Modern plants are equipped to produce WMA and specialized cold mixes.
Recycling of Reclaimed Asphalt Pavement (RAP): Asphalt mixing plants play a crucial role in sustainable construction by incorporating significant percentages of milled old asphalt pavement (RAP) into new mixes.

Key Configurations:

Material Superiority: High-chromium cast iron (HC250-HC600) / Alloy steel with proprietary heat treatment
Wear Resistance: Surface hardness up to 58-62 HRC (Validated by metallographic analysis)
Zero-Deformation Guarantee: Proprietary quenching process eliminates warpage
Custom Engineering: Supports non-standard designs for OEM applications

Core Technologies

Smart Heat Treatment
Patented process ensures uniform hardness gradient while preventing quenching deformation

Precision Manufacturing

Vertical flaskless molding lines for dimensional accuracy (±0.5mm)
Robotic shot-blasting surface treatment

Quality Assurance

In-house spectroscopy analysis (ARL-660)
Metallographic microscope inspection
ISO 9001 certified production control
