Description
The Los Angeles 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.This design follows the ASTM-preferred design and features a 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. The enclosed chain drive rotates the
drum without a conventional slip clutch. This positive drive delivers
greater accuracy. The self-contained wLA Abrasionorm-drive motorized
speed reducer has anti-friction bearings and sealLA Abrasioned
lubrication. The 1hp, electronically-controlled motor is equipped large,
push-button controls and an automatic overload cutout.Unit Includes user-configured, revolution counter, a material catch
pan and one abrasion charge consisting of 12 hardened-steel balls.
