FAQ
Q: What are the roller track and rollers of a concrete mixer drum? What is their function?
A: The roller track is a circular rail fixed on the outer wall of the mixing drum, and the rollers are wheels mounted on the frame to support the drum. Together, they form the drum's rotary support system. Their primary roles are to bear the weight of the entire drum and the concrete inside it and to ensure the drum rotates smoothly with minimal resistance. They are key load‑bearing components of the mixer.
Q: Why is the roller track designed as a hollow ring structure?
A: Based on your delivery time and budget needs, we offer various options including air freight, sea freight (FCL or LCL), and international express (e.g., DHL, FedEx).
Q: What manufacturing process is typically used for roller tracks? What are the advantages of "forging"?
A: Roller tracks are typically manufactured by forging. Compared with casting, forging offers the following advantages:
• Denser microstructure: Refines grain and closes internal voids, greatly improving toughness and fatigue strength.
• Better mechanical properties: Continuous fiber flow lines provide higher load‑bearing capacity.
• Fewer defects: Effectively reduces casting defects such as sand holes and porosity, making it more suitable for key components subjected to high cyclic loads.
Q: What is "normalizing" treatment for roller tracks? What is its purpose?
A: Normalizing is a heat‑treatment process in which the steel part is heated to the austenitizing temperature and then cooled in air. Its purposes are:
• To homogenize the structure and refine the grain, eliminating internal stresses induced during forging or machining.
• To improve the overall mechanical properties of the material, preparing it for subsequent machining or final heat treatment (e.g., quenching), thus ensuring the roller track achieves more stable and uniform performance.
