Loss Angeles Abrasion Testing Machine

About Loss Angeles Abrasion Testing Machine

The Los Angeles Abrasion Testing Machine is a standard laboratory equipment used for determining the abrasion resistance and durability of coarse aggregates. It is widely used in highway engineering laboratories and construction material testing facilities to evaluate the suitability of aggregates for road construction, concrete works, and other heavy-duty applications.

This machine consists of a rotating steel drum mounted on a sturdy frame, along with a set of abrasive steel balls. The aggregate sample is placed inside the drum along with the abrasive charge, and the drum is rotated at a specified speed. The resulting wear and degradation of the aggregates are measured to determine their abrasion value.

Manufactured with a heavy-duty steel structure and precision-engineered components, the Los Angeles Abrasion Testing Machine ensures accurate, consistent, and reliable test results. It is designed for long-term laboratory use with minimal maintenance.

Key Features:

• Heavy-duty rotating steel drum
• High-precision abrasion testing mechanism
• Sturdy and vibration-free frame construction
• Accurate determination of aggregate durability
• Easy operation and low maintenance
• Designed as per standard testing specifications

Applications:

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

Working Principle:

The machine rotates the aggregate sample with abrasive steel balls inside a drum. The percentage loss in weight after a specified number of rotations indicates the abrasion value, reflecting the hardness and durability of the aggregates.
