Miller Erosion Test

This test bench is designed for determination of the abrasive effect of mud according to the “Miller” Number-system or abrasion properties of materials against a suspension (ASTM Method). This test stand is suitable for fine, wash-out types of wear. We have also converted it to test abrasion on sieves.

Test Bench Description

description in picture of miller erosion

Standard:  ASTM G75

Load (max):  Up to ca. 20N

Speed (Standard):  Up to ca. 0.3 m /sek

Sample 1:  Block

Sample 2:  Slurry, dry sand

Results:  Weight loss, damage pattern

Conversions:  Slurry + dry sand against fabrics and sieves and lower load option

Note:  The given parameters are according to ASTM Standard. Others on request.


One of the benefits of this test is its international standards. This allows to compare results with existing data.  There are standards for two test setups, either with a standard wear sample or with a standard slurry.

The abrasiveness of a slurry is measured as the “Miller number”, while the use of a standard slurry can be used to determine the resistance of a solid or a coating material against abrasion (SAR number: slurry abrasion response).

To determine the abrasion resistance of a test sample, it is subjected to an oscillatory friction movement in the suspension. Up to four test specimens can be installed and tested at the same time. The loaded specimens are oscillating in the slurry-bath.
