Hardgrove Grindability Index Wikipedia

Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined

Hardgrove Grindability, Coal Analysis, Kentucky Geological

In a Hardgrove test, samples are crushed to a specified size, air-dried, and weighed, then run through a laboratory grinding (milling) machine for 60 grinds (rotations). The milled sample is then placed on a sieve of set specifications. The amount of sample that passes through the sieve is used to calculate the Hardgrove grindability index.

Application of the Hardgrove grindability index in

The Hardgrove grindability test, commonly used in coal characterization, was conducted on 13 Mississippian carbonates from Kentucky, Tennessee and Illinois. The results demonstrated that the grindability increases with a decrease in the SiO2/(MgCO3+CaCO3) ratio, with fine-grained and petrographically-complex stones having lower grindabilities.

Interrelationship of coal grinding properties and coal

Aug 01, 1998· The Hardgrove grindability index (HGI) is a widely used coal-quality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the high-volatile

Crushing properties of coal SpringerLink

Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient. There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.
