DORRY ABRASION TESTING MACHINE AZA0988

The AZA0988 Dorry Abrasion Testing Machine by Azalab is a robust, motorized laboratory instrument designed to measure the abrasion resistance (wear loss) of coarse aggregates used in road construction, railway ballast, and structural concrete. This machine provides consistent, repeatable test results in accordance with IS 2386 (Part IV) standards, helping engineers and laboratories ensure material durability and performance.


Key Functions

  • Evaluates abrasion and wear resistance of aggregates
  • Simulates real-life mechanical rubbing and surface wear
  • Ensures quality control for construction materials
  • Supports research and teaching in civil engineering labs

Description

Standards Compliance

  • IS:2386 (Part IV)


Working Principle

The aggregate sample is placed inside a steel test cylinder mounted on a rotating steel disc. A weighted loading arm applies a constant force on the sample. As the disc rotates at a controlled speed, the sample rubs against emery powder, simulating abrasive wear.

After the specified revolutions, the sample is cleaned, dried, and weighed. The percentage weight loss represents the abrasion value.


Key Features

  • Heavy-duty motorized steel disc system

  • Precisely machined loading arm with dead weights

  • Stable, vibration-resistant steel frame

  • Simple operation with low maintenance

  • Designed for long-term laboratory use
