Dorry Abrasion Testing Machine

About Dorry Abrasion Testing Machine

The Dorry Abrasion Testing Machine is a precision laboratory equipment used for determining the abrasion resistance and hardness of aggregates used in road construction and civil engineering works. It is widely used in highway laboratories and construction material testing facilities to evaluate the wear and tear resistance of stones and aggregates under frictional forces.

This machine operates by subjecting aggregate samples to controlled rubbing action against a standard abrasive surface. The loss in weight of the sample after testing indicates its abrasion value, which helps determine the suitability of aggregates for pavement and heavy-duty construction applications.

Manufactured with a heavy-duty steel frame and high-quality rotating mechanism, the Dorry Abrasion Testing Machine ensures accurate, consistent, and reliable test results. It is designed for long-term laboratory use with minimal maintenance requirements.

Key Features:

• Heavy-duty and rigid steel construction
• High-precision rotating abrasion mechanism
• Accurate determination of aggregate wear resistance
• Smooth and stable operation
• Designed for long service life
• Easy operation and low maintenance

Applications:

• Highway and road construction laboratories
• Civil engineering material testing labs
• Aggregate quality control departments
• Infrastructure development projects
• Research and testing institutions

Working Principle:

The machine measures abrasion resistance by rotating aggregate samples against a standard abrasive surface under controlled conditions. The percentage loss in weight indicates the hardness and durability of the aggregate.
