LA Abrasion Machine

The LA abrasion machine is used to measure the degradation of mineral aggregate of standard gradings resulting from a combination of actions, including abrasion or attrition, impact and grinding in a rotating steel drum containing a specified number of steel spheres.

The test is widely used as an indicator of the relative quality of various sources of aggregate having similar mineral compositions.

The design follows the ASTM-preferred:

• Welded, structural-steel frame, fabricated .5"-thick (913mm) abrasion-resistant steel drum, a removable shelf bolted to the drum, and a balanced drum assembly for easy rotation by hand.
• Enclosed chain drive that rotates the drum without a conventional slip clutch. This positive drive delivers greater testing accuracy.
• Self-contained worm-drive, motorized speed reducer has anti-friction bearings and sealed lubrication.
• 1hp, electronically-controlled motor equipped with large, push-button controls and an automatic overload cutoff.
• Controls that can be removed from the abrasion machine and mounted outside a sound enclosure or mounted on a nearby wall.

Unit includes a user-configured revolution counter, a material catch pan, and one abrasion charge consisting of 12 hardened-steel balls.

The electrical requirements are 115v/60Hz.
