Coarse Aggregate And Crushed Rock Abrasion Testing Machine

Los angles abrasion testing equipment, compliant with I.S. 2386 Part IV regulations and tolerances, for determining the resistance to wear of small size coarse aggregate and crushed rock. A hollow drum is fixed on a robust frame that is supported by ball bearings. A detachable shelf that runs the length of the inside of the drum gathers abrasive charges and prevents them from falling on the cover. An electric motor drives a heavy-duty gear that rotates the drum at 30-33 rpm. The motor is designed to run on 440 volts, three phase AC power. Abrasive charges include 12 hardened steel/cast iron spheres with a diameter of 48 mm and a weight of 390 to 445 grammes, and a Preset type counter to turn the unit off at the required rotations for use with the Los Angles abrasion testing machine Since 1976, we've been producing testing machines, sieve shakers, and gyrator sieve shakers.
