Keep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball.About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss.

10mm Ball 150kg Brale 100kg 1/16" Ball . Diamond Pyramid 120kg. Tensile strength (Approx) Reference table: Steel Hardness conversion chart. Since the various types of hardness tests do not all measure the same combination of material properties, conversion from one hardness scale to another is only an approximate process.

I am looking for a Hardness color chart that would help me choose among my hundreds grinding bits ( most are Dremel's but some aren't ). I noticed that colors look the same among suppliers, do they refer to the same hardness ? Can you recommend a good web site on Dremel rotary tool, particulary on grinding with Dremel rotary tool. Regards !
Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher. Use a coarse grit for fast, aggressive stock removal and finer grits for less stock removal but better surface finish. Grinding wheel hardness
Union Process is the source for the most up-to-date information on grinding balls and other media. Click the link above to view a detailed sheet, outlining factors to consider when selecting grinding media, along with specifications on the most common types of media.
Sep 19, 2018· There are several methods for volumetric hardness measurement of grinding balls.The method for hardenability determining, namely, the method of end hardening with a hardness measurement interval from 1.5mm to 3mm (GOST 5657-69) takes as the basis of all methods.
The grinding balls samples should be prepared such way, that their properties will not changed as a result of mechanical or other processing. The grinding on a surface grinding machine is the best way to prepare the grinding balls surface for hardness measures. A special matrix has created for steel grinding balls. From 2 to 5 grinding balls placed in matrix and simultaneous polish them.

Most SAG grinding operations currently use ball size between 5.5 and 6 inch maximum size, However, in most cases the use of these ball sizes hasn't been justify. ... Grinding & Classification Circuits. ... ball size need to include ball hardness/ or hardness profile as well, particularly within the context of how a SAG mill is operated; i.e ...
A 4.6.1. with the exception of heat–treated wire of diameter .100" (2.54 mm) and larger, the Rockwell Hardness Test is not recommended for round wire. On such heat–treated wire the specimen shall be flatten on two parallel sides by grinding. For round wire the Tensile Strength Test is greatly preferred to the Rockwell Hardness Test.

The removal rate in grinding and polishing is closely related to the abrasives used. Diamonds are one of the hardest known materials, as they have a hardness of approximately 8,000 HV. That means it can easily cut through all materials and phases. ... and MD-Allegro should be used for fine grinding of materials with a hardness of 150 HV and higher.
The grinding balls surface hardness defines on two diametrically opposite platforms. Four measurements perform at each platform for the hardness determination by Rockwell method. The first three measurements perform at the vertices of imaginary equilateral triangle .
