Micro-Deval Apparatus

The Micro-Deval test measures abrasion resistance and durability of mineral aggregates. Placed in a sealed stainless steel jar an abrasive charge up to 5,000g of 9.5mm diameter stainless steel balls and water. Rotated at 100 RPM for 2 hours. Percentage loss in the graduation results at completion determines quality of an aggregate. Small equipment size, lower sample quantities and a simpler procedure make the method easier and less costly.

  • Multi-function electronic controller tracks time, speed and total revolutions
  • Easier, safer and less expensive to operate
  • Lexan doors and safety interlocks ensure no exposed moving parts


  • Micro-Deval Apparatus
  • Two jars
  • Two sets of 5,500g abrasive charge
  • Magnet to assist in removing abrasive charge after a test
