DEVEL ATTRITION TESTER AZA0989
The AZA0989 Devel Attrition Tester by Azalab is a heavy-duty laboratory machine designed to evaluate the resistance of coarse aggregates to abrasion and wear. It is widely used in road construction, railway ballast testing, and concrete material laboratories to ensure aggregates meet strength and durability requirements.
This equipment complies with IS 2386 (Part IV) and ASTM C131 / ASTM C535 standards, providing reliable and repeatable test results.
Key Applications
- Road and highway material testing
- Railway ballast quality assessment
- Concrete mix design durability testing
- Civil engineering research & academic laboratories
Description
Working Principle
The aggregate sample and hardened steel balls (abrasive charge) are placed inside a rotating steel drum. The drum rotates at a controlled speed of 30–33 RPM, producing rolling and impact actions.
After the test cycle, the material is sieved and the percentage of fines is calculated as the attrition value.
Lower attrition value = Stronger, more durable aggregate.
Main Features
-
Heavy-duty steel drum construction
-
Motorized operation with stable, vibration-free frame
-
Digital timer with auto cut-off
-
User-friendly operation with high test repeatability
-
Suitable for both laboratory and educational use
