Turbidimeter TURB 430 IR-for dust test

Date: Sep 08,2016

As we know that high fine dust content on abrasive grains causes problems with silo fillings, mixture dosing and wetting ratios in mixtures.

To measure fine dust content on abrasive grains, we use a nephelometer:  Turbidimeter TURB 430 IR, manufactured by WTW GmbH. 

Nephelometer measures turbidity
 - cloudiness or haziness of a fluid caused by individual particles (suspended solids). Instead of total dust content, we rather measure amount of fine unbound particles larger than 1 nm.

Turbidity measurement is based on observation of light scattering through the sample and comparison with standard suspension with known turbidity.

With this
nephelometer, Futong can control and test the cleanliness of our Brown Fused Alumina, White Fused Alumina, Black Silicon Carbide, Green Silicon Carbide etc. Thus we can meet customers different requirements of the grain cleanliness.
