HGI (Hardgrove Grindability Index) Tester is a test instrument designed to determine and calculate the grindability index value of coal. Manufactured in full compliance with the ASTM D409/D409M – 24 standard, this device reliably and precisely measures the grindability characteristics of coal samples.
Delivery Contents:
The device is supplied with four sieves as specified in the standard. Additionally, four standardized reference samples with verified HGI values, sourced from abroad, are provided with the device. These reference samples are used to ensure calibration accuracy and the reliability of test results.
The HGI Hardgrove Grindability Index Device is widely used in industry to assess the grindability properties of coal samples. By providing reliable test results, it offers critical data on coal processability, contributing to the optimization of production processes.
