The Hardgrove Grindability Index (HGI) is a measure of coal’s resistance to crushing. Read more Grinding studies, and the resulting HGI, allow many different types of coal users to evaluate how coals will perform in their mills, allowing them to estimate grinding power
LC-100, Hardgrove Grindability Tester Gilson Company Hardgrove Grindability measures relative ease of pulverization of coals sieve size coal and eight 1in (25.4mm) diameter polished steel grinding balls are The LC-82 Motorized Disk Mill (listed seperately) meets ASTM requirements for
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.
HARDGROVE GRINDABILITY TEST The Hardgrove Grindability test is a measure of coals resistance to crushing and attempts to reproduce the effects of continuous coal pulverization in a mill A 50gram sample of prepared coal of uniform size range is placed inside a grinding unit The unit undergoes a standard number of revolutions under a.
The design of the coal mill mainly depends on the HGI. Although the Hardgrove machine is not costly, it is not a routine testing item in coal-fired power plants. So, a mathematical method to predict the HGI can be maceral content, and coal rank (Rmax
The ATOX coal mill is suited for various installation types, whether inert or non-inert, and direct or indirect firing systems. An inert system designed for indirect firing is the most common solution for cement plants. Equipped with the high-efficiency RAKM dynamic separator, the ATOX coal mill will grind any type of coal to the required
The resulting Hardgrove Grindability Index (HGI) provides a measure of the energy required in a grinding process or a measure of yield for given energy input. A prepared 50g sample of No. 16—No. 30 sieve size coal and eight 1in (25.4mm) diameter polished steel grinding balls are placed in a stationary bowl having a machined circular track.
