The Los Angeles Abrasion Machine is designed to evaluate the resistance of aggregates to abrasion and fragmentation. This machine plays a vital role in determining the durability of mineral aggregates, which is crucial for construction projects. With a robust steel cylinder measuring 711 mm in diameter and 508 mm in length, the drum rotates at speeds between 31 and 33 revolutions per minute (rpm), simulating real-world wear and tear.

The Los Angeles Abrasion Machine measures aggregate degradation through abrasion, impact, and grinding. This method utilizes hardened steel balls and a rotating drum to mimic wear conditions. It’s widely used to assess aggregate quality for construction projects, ensuring materials meet the required standards of resistance.

With features such as a noise-reducing cabinet and automatic stopping mechanisms, the Los Angeles Abrasion Machine ensures efficient, accurate, and safe testing. This machine is an essential tool for determining aggregate durability, and it plays a critical role in selecting high-quality materials for various construction applications.

The Los Angeles Abrasion Machine is equipped with advanced features for reliable performance. It includes an automatic digital counter to preset the required number of drum revolutions. Additionally, the machine has a balanced drum assembly, allowing easy loading and unloading of materials without tilting.

Constructed according to ASTM standards, this machine has a welded steel frame and an abrasion-resistant drum, ensuring durability. The enclosed chain drive and electronically-controlled motor provide precise testing, while a safety feature ensures the machine halts automatically when the door is opened, conforming to CE safety directives.
