RESULTS OF COOPERATIVE TESTS USING THE LOS ANGELES ABRASION MACHINE

CHECK ABRASION TESTS WERE MADE ON A SAMPLE OF CRUSHED LIMESTONE OF UNIFORM QUALITY TO STUDY THE EFFECT ON THE TEST RESULT OF DIFFERENCES IN THE DESIGN AND OPERATION OF LOS ANGELES ABRASION MACHINES. REMARKABLY CONCORDANT RESULTS WERE OBTAINED, THE MEAN DEVIATION FROM THE AVERAGE FOR ALL LABORATORIES BEING ONLY 5.6 PERCENT. STUDY OF THE FEATURES OF THE DIFFERENT MACHINES SHOWS THAT THE WEIGHT OF THE ABRASIVE CHARGE AND THE DESIGN OF THE SHELF AFFECT THE TEST RESULT TO THE GREATEST EXTENT. SUGGESTIONS REGARDING THE DESIGN OF THE SHELF ARE MADE, AND AGREEMENT WITH LATEST REVISED SPECIFICATIONS FOR THE CONSTRUCTION AND OPERATION OF THE MACHINE IS RECOMMENDED. /AUTHOR/
