LOS ANGELES ABRASION TESTING MACHINE (R191)

Category: Aggregate

Product Code: R191

Category: AGGREGATE

Sub-Category: ABRASION RESISTANCE

  • The Los Angeles Abrasion Tester is used to evaluate the resistance of coarse aggregates to abrasion and impact, simulating real-world conditions that aggregates face in pavements and other structures.
  • This apparatus assesses the degradation of aggregates through a combination of abrasion, impact, and grinding actions within a rotating steel drum containing a specified number of steel spheres.
  • The test provides an indicator of the relative quality or competence of various sources of aggregate having similar mineral compositions, aiding in material selection for construction projects.
  • The machine features a robust steel cylinder with a wall thickness of 12 mm, an internal diameter of 711 mm, and a length of 508 mm, ensuring durability and compliance with international standards.
  • An automatic digital counter is integrated to display the number of drum revolutions and automatically stop the motor after the required number of revolutions, enhancing test accuracy and repeatability.
  • Abrasive Charges and Noise Reduction and Safety Cabinet should be ordered separately.
