The Los Angeles Abrasion Machine is designed to test the wear resistance of small coarse aggregates and crushed rock. It features a hollow cylinder mounted on a robust frame with ball bearings, ensuring smooth rotation. A detachable internal shelf holds the abrasive charge, preventing it from falling onto the cover. The drum rotates at 30-33 rpm, driven by an electric motor connected to a heavy-duty reduction gear. The motor operates on a 415 V, 3-phase, 50 Hz AC supply. This setup is used to simulate the abrasion and impact aggregates experience in real-world conditions, helping assess their durability for construction purposes.
