Micro-Deval Testing Machine

Micro Deval Testing Machine used to determine the resistance to wear of 25-50mm size aggregates.

The machine consists of a steel frame,two rotating bars with capacity of 4 cylinders.

Device is equipped with two stainless steel cylinders, and 20 kg of ∅ 10 mm stainless steel balls and automatic digital counter which allows machine to stop automatically at the preset number of revolutions.
 
Stainless steel Ø200*154 drums are rotating at speed of 100 (±5) r.p.m.

Soundproof Safety Cabinet should be ordered separately during the order stage.

What is Micro-Deval Test?
Micro-Deval Test is an aggregate strength test based on abrading the aggregate in a certain environment, at a certain rotation speed and for a certain number of turns, and then proportioning the material passing through the sieve determined by the standards according to the initial material amount.
