The Micro-Deval testing machine, Nordic version, is used to determine aggregates’ resistance to wear by abrasion from studded tires (Nordic Test to EN 1097-9).

It consists of a motor driven actuator (including inverter) which transmits the rotation directly to the jars. Each jar is built with an attachment that transfers the rotation to the proximal jar. The direct application of rotation forces ensures strict compliance to the rotating speed prescribed by the Standards.

The integrated automatic counter can either be pre-set to a total number of revolutions or maximum working time. Totally safe, all moving parts are enclosed in a CE-conforming soundproof safety cabinet that automatically stops when the lid is open. Compact and ergonomic, the Micro-Deval will maximize your laboratory’s space as it can either be positioned on a laboratory bench or on its own optional dedicated base.
Supplied without cylinders and steel spheres, these can be purchased separately and adapted to Nordic Test to EN 1097-9 Standard. The machine can be used with up to two stainless steel cylinders model 48-D5242/EN3, featuring an internal diameter of 206.5 mm and internal height of 355 mm plus three ribs 333 mm long.
