The Los Angeles abrasion machine is a fundamental device used to evaluate the resistance of aggregates to wear and fragmentation. It is designed to comply with major international standards for material durability testing.

The unit can be easily configured to meet ASTM and EN standards, with adjustable settings for the required number of rotations.

The device consists of a cylindrical steel drum with an inner diameter of 711 mm and an internal length of 508 mm, coupled with an electronic control unit. The drum operates at a speed of 31–33 rpm. The equipment features an automatic counter that stops the machine once the preset number of cycles has been completed. A collection tray is included for easy sample removal.

In accordance with EN standards, the abrasive ball set and the 1.6 mm sieve must be ordered separately. For AASHTO and ASTM standards, the abrasive ball set and the 1.7 mm mesh sieve must also be ordered separately.



The NT-A0060 Los Angeles abrasion machine is a reference equipment designed to evaluate the resistance of aggregates to wear and fragmentation. It is used to determine the durability of granular materials subjected to repeated mechanical stress, particularly in civil engineering, road infrastructure, and construction applications.

This apparatus is engineered to ensure reliable, repeatable results while fully complying with the requirements of major international standards for aggregate durability testing.

  • NT-A0230 Micro-Deval Test Apparatus



General description

The NT-A0230 Micro-Deval Test Apparatus is a laboratory testing device designed to determine the resistance to wear of aggregates sized between 25 and 50 mm. The test is performed in accordance with international standards to assess the durability of materials used in applications such as road construction and railway ballast.



Principle and operation

The apparatus simulates aggregate wear by abrasion in a wet environment inside rotating drums. It can operate with:

  • 4 drums of Ø200 × 154 mm
  • or 2 drums of Ø200 × 400 mm

The rotation speed is set to 100 ± 5 rpm. The unit is equipped with a user-adjustable digital revolution counter and automatically stops at the end of the test cycle.
