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 empirically using a sample mill according to the following procedure.

The Hardgrove Grindability test is commonly used to characterize the milling behavior of coals. The test, first conceived by Hardgrove (1931) and later modified to the current constant weight test in 1951 (ASTM D409 71, 1971 ISO 5074, 1994c), attempts to mimic the operation of a continuous coal pulverizer using a batch process.

The Ball Mill Grindability of ores is generally determined by the Bond standard grindability index test method However this test and procedure is not applicable to fine materials such as sands the grindability of fine materials must therefore be determined by a comparative grinding method for which a reference material of know grindability is.
2 Apr 2019 Hardgrove grindability index, associated mainly with vertical spindle mills and the other is the Bond's grindability index, associated with tumbling mills.
Hardgrove Grindability Index (HGI) Mining SGS. The Hardgrove Grindability Index (HGI) is a measure of coal’s resistance to crushing. 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 requirements and throughput capacities.
Grindability For Vertical Mills Vertical roller mills125 Мб VERTICAL ROLLER MILLS I The first LM6333 by Dr Daniel Strohmeyer Loesche Germany Figure 1 working principle of Loesche cement and slag mills 1The assumption for the grindability for the clinker was approximately 15kWht making this material of comparitively good grindability.
Material grindability is an important factor affecting the yield. When material grindability deteriorates, grinding cycles number of vertical mill increases significantly. Since most of the material is crushed into fine powder, but it can not meet the requirements of the finished product, it cannot be taken out of the mill.
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness.
Grindability for vertical mills MC World. 2015 11 09 (HGI) being the standard test for vertical spindle mills [7,8], and the Bond Work Index (BWI) for tube and ball mills [9,10]. No stan dard grindability tests currently exist for biomass, and there have only been limited studies on the use of standard grindability.
Vertical roller mill grindabilithy analysis. grindability for vertical mills Based on screening analysis laser sie analysis grindability and rigidity tests of samples collected on line from a cement and a power plant a simulation of the grinding process in vertical roller mills vertical roller mill.

The vertical roller mill is well known in the cement and power plant industries as the preferred.
As the comminution performance depends on the grinding load (which is different for vertical roller mills in comparison to ball mills), the sample characterization must be adapted as well. For the Zeisel and Hardgrove grindability tests, the feed sample with its precisely defined particle size is crushed by pressure and friction between a.
Abstract Based on screening analysis, laser size analysis, grindability and rigidity tests of samples collected on line from a cement and a power plant, a simulation of the grinding process in vertical roller mills was carried out.

Vertical spindle machines use cup, cylinder, or segmented wheels. Many are equipped with multiple spindles to successively rough, semi finish, and finish large castings, forgings, and welded fabrications. Workholding devices. Almost any workholding device used on a milling machine or drill press can be used on surface grinders.
The grindability of feed directly affects the mill output, power consumption and service life of roll liner. Material is easy to grind, crush and grind, and produce superfine powder. Conversely, materials with poor grindability need repeated grinding and greater grinding pressure to increase grinding power consumption, accelerate the wear of.
