Product code IT-A120
Los Angeles abrasion machine
Machine for determining the abrasion and fragmentation resistance of crushed stone by the Los Angeles method with an automatic revolution counter.
- 24-month warranty and spare parts from stock
- Commissioning, staff training and methodological support
- Assistance with equipment certification as part of your laboratory
Description
The Los Angeles machine determines the resistance of crushed stone and gravel to abrasion and impact: the sample rotates in a steel drum together with a charge of cast iron balls, after which the mass loss on a control sieve is evaluated.
The electronic control unit sets the number of revolutions with automatic stop at the end of the cycle — 500 or 1000 revolutions without operator involvement. A removable galvanized steel tray simplifies sample discharge.
A sound-insulating enclosure with a door-open start interlock reduces the noise level and ensures the safety of laboratory personnel.
Features
- Automatic revolution counter with stop function
- Set of 12 steel balls in the scope of supply
- Sound-insulating protective enclosure with interlock
- Sample discharge tray included
- 12 mm drum wall thickness for extended service life
