Product Code : EL-AD-10594
Product Description
Micro-Deval Apparatus, 120V 60Hz
An aggregate sample is placed in a sealed stainless steel jar with an abrasive charge of up to 5,000g of 9.5mm diameter stainless steel balls and water, then rotated at 100rpm for two hours.
The Micro-Deval test measures abrasion resistance and durability of mineral aggregates.
Aggregate quality is determined by percentage loss in gradation results at completion.
Smaller equipment size, lower sample quantities and a simpler procedure make the method easier and less costly to perform than traditional methods.
The Micro-Deval meets current ASTM, AASHTO, and Canadian test methods, as well as more stringent Texas DOT requirements.
A sophisticated electronic controller with optical sensing system accurately tracks test time, total revolutions and rpm of jars.
The Micro-Deval Apparatus is a second generation, state-of-the-art machine.
The jars revolve behind closed polycarbonate doors with safety interlocks so no moving parts are exposed during operation.
Test duration may be controlled by either elapsed time or total revolutions.
Jars stop within a fraction of one revolution at test termination.
Jar revolution and speed data may also be used as a verification of machine performance.
Each tier carries one stainless steel 5L jar, 194mm ID, 170mm internal height with locking cover.
Power to the rubber-covered rollers is supplied by a 0.75hp electric motor through a gear transmission and chain drive.
The Micro-Deval machine is a two-tier unit with a sturdy steel frame.
