Product Code : EL-ELE-17469
Applications:
This machine is used to find the percentage wear due to relative rubbing action between the aggregates and steel balls used as abrasive charge. The oven-dried aggregates are weighed and rotated along with abrasive charge in the machine for the 500 or 1000 revolutions and percentage of wear so found out is reported Los Angeles abrasion value.
The machine consist of a hollow steel cylinder, closed at both ends, having inside diameter of 700 mm and inside length of 500 mm
