On the one hand, the addition of chromium in casting grinding ball decreases the carbon content of the eutectic point and decreases the austenite area in the phase diagram. On the other hand, the type of carbide structure changes from reticulate M3C type to isolated M7C3 type, and the hardness of carbide increases, from 850 ~ 1100HV of M7C3 to ...
At present, most of the grinding media used in cement industry are high-chromium balls. With the continuous development of cement grinding technology, the specific surface area and fineness of cement are required to be even higher. As a cement company, the correct selection of grinding materials is particularly important.
The detailed deformation mechanism and its microstructural modifications of white cast iron grinding balls used in comminution have been investigated using transmission electron microscopy (TEM) and XRD. De-shaping is the primary mode of ball consumption, and fracture of balls is a relatively uncommon failure mode. Deshaping is the manifestation of abrasive wear caused during the operation ...

phology of M7C3 eutectic carbides in high chromium white cast iron. The presented results are part of the research con-cerning the possibility of improving the properties of chro-mium white cast iron alloying with vanadium, particularly impact toughness, which is used for grinding balls ore, coal, gravel, and cement.
The grinding media may be the ore itself (autogenous grinding), bars, balls, or cylpebs, or even the ore itself together with a small amount of balls (semi-autogenous grinding). A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semi-autogenous grinding, and therefore ...

The morphology and distribution of carbide precipitates strongly influence the mechanical and other properties of such a multiphase objects . If the relationship between subsurface service life and microstructure can be explored and controlled, the grinding service life of high chromium cast balls will be greatly improved.
The microstructure of medium chromium white cast iron grinding ball can be regarded as a mixture of spongy reticulated M 3 C type cementite inlaid with austenite and alloy carbide transformation mainly M 7 C 3 type distributed in a three-dimensional open framework. The grinding balls' strength and toughness depend on the brittle M 3 C carbide phase's volume percentage and distribution.
