Mining Wear Solutions

Asphalt plants Wear Challenges

Asphalt plants operate under high-temperature, high-friction conditions. Components are exposed to thermal cycling, material abrasion, and chemical wear from bitumen and aggregates.

Key Challenges Include:

  • Frequent wear of mixing blades, paddles, and liners

  • Deformation or cracking caused by thermal stress

  • High replacement frequency increases maintenance cost and downtime

  • Inconsistent quality due to wear-related mixing inefficiencies

MANUFACTURING CAPABILITY

  • Advanced DISA vertical molding line

    Advanced DISA vertical molding line

    The DISA vertical molding line ensures high-efficiency, high-precision sand molding for casting asphalt equipment wear parts. It delivers excellent dimensional accuracy and surface finish, ideal for high-wear components like mixer blades or auger segments. Its automation boosts productivity and consistency, supporting large-scale production with minimal defects.

  • Lost foam casting of large complex parts

    Lost foam casting of large complex parts

    Lost foam casting is ideal for complex or large asphalt wear parts such as mixing arms or liners. It enables near-net-shape casting with minimal joints and machining, reducing material waste and production time. This method ensures high casting integrity, making it suitable for components exposed to high temperature and abrasive asphalt mixtures.

  • 3D printing prototyping

    3D printing prototyping

    3D printing prototyping accelerates the development of new or customized wear-resistant parts for asphalt equipment. It allows engineers to quickly test part geometry, fitment, and performance before tooling investment. This shortens the design cycle and enhances precision, especially for parts subjected to extreme mechanical and thermal stress in paving and mixing applications.

  • In-house heat treatment and machining

    In-house heat treatment and machining

    In-house heat treatment significantly improves the hardness and wear resistance of cast parts like scrapers and paddles, ensuring durability under harsh asphalt processing conditions. Precision machining further guarantees dimensional accuracy and surface quality, enabling proper fit and extended service life of wear components used in continuous, high-load asphalt equipment operations.
