SDHG60a / Hardgrove Grindability Index Tester HGI / Coal

Intelligent Controlling System / High Automation / ISO 5074:1994

Application

This instrument can be used to test the coal grindability by Hardgrove method.

Hardgrove Grindability Index Tester is a special tester for testing the grindability of soft coal and blind coal. Takes grinding law as the theoretical basis (The energy consumed in coal grinding in proportional to the new surface area of coal dust).
