Micro-Deval Test Apparatus
Laboratory Type Testing Device for Determinating the Resistance of Aggregates to Wear
The Micro-Deval Test Apparatus is designed to determine the resistance to wear of 25–50 mm sized aggregates. This test is conducted in accordance with international standards to evaluate the durability of materials used in applications such as road construction and railway ballast. The device can operate with 4 drums of Ø200 x 154 mm or 2 drums of Ø200 x 400 mm. Drum rotation speed is 100 ± 5 rpm. Device is equipped with a user-adjustable digital automatic revolution counter, and the device stops automatically at the end of the test.
