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
