LA Abrasion Machine (Model AG-7500)
Determine Aggregate Toughness and Abrasion Resistance
The Los Angeles (LA) Abrasion Machine is an essential piece of equipment for any materials testing lab. It is expertly designed to measure the resistance of mineral aggregates to degradation from a combination of actions, including abrasion, attrition, impact, and grinding. The test is performed by rotating an aggregate sample in a steel drum with a specified number of steel spheres for a set number of revolutions.
This test is widely recognized and used globally as a key indicator of the relative quality and toughness of aggregates. By determining the percentage of wear, engineers and technicians can assess the suitability of an aggregate source for use in construction projects like roads and concrete structures, ensuring durability and longevity.
Superior Design and Functionality
Our AG-7500 model adheres strictly to ASTM-preferred design standards to deliver unparalleled accuracy and reliability.
Key Features:
- Robust Construction: The machine is built on a heavy-duty, welded structural steel frame to ensure stability and long-term durability.
- Abrasion-Resistant Drum: The drum is fabricated from 0.5" (13mm) thick, wear-resistant steel, featuring a removable interior shelf bolted securely in place. The drum assembly is precisely balanced for easy manual rotation when needed.
- Accurate, Enclosed Drive System: A chain drive system rotates the drum, eliminating the need for a conventional slip clutch. This positive drive mechanism provides greater rotational accuracy and consistent test results.
- High-Performance Motor: A self-contained, worm-drive motorized speed reducer with anti-friction bearings and sealed lubrication ensures smooth and quiet operation. The powerful 1hp electronically-controlled motor is equipped with large, easy-to-use push-button controls and an automatic overload cutout for safety.
- User-Friendly Controls: The machine includes a user-configurable digital revolution counter, allowing for precise control over the test duration.
What's Included: The AG-7500 unit comes complete with:
- An integrated digital revolution counter
- A material catch pan for collecting the sample after testing
- One standard abrasion charge, consisting of 12 hardened-steel balls
Specifications:
- Dimensions (W x D x H): 39" x 29" x 37" (991 x 737 x 940mm)
