Cast Grinding Media Ball-China Cast Grinding Media Ball Dia. 20mm-150mm High Quality High Chromium Casting Grinding Media Ball for Ball Mill. US $ 900-980 / Ton FOB. MOQ: 20 Tons. Since 2020. Main Products. Grinding Ball. Contact Supplier. Shandong
Grinding balls of different compositions ranging from mild steel (MS), martensitic stainless steel (MSS), high carbon low alloy (HCLA) steel and high chromium cast iron (HCCI), each of 25.4 mm diameter, were wear tested in a 203-mm diameter porcelain mill (see Table 1) under different conditions.
• Cast grinding media has Chromium Carbide in its main structure giving it a much stronger martensitic structure versus forged grinding media. • On forged balls grinding position is important. According to grinding position different abrasions occur This causes non-homogenous abrasions.This does not occur on cast balls.
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 …
The M7C3 type carbide is distributed in the microstructure of high chromium cast iron grinding ball, which makes it have higher hardness and better toughness. Compared with other grinding balls, it has the advantages of low unit consumption and low crushing rate, so it has attracted material technicians' attention.
Grinding Media,Steel Grinding Media,Grinding Media Balls. The steel shots, balls and beads ball mill media are preferred for contamination free and speedy (dry / wet) milling, grinding of solids, liquids dispersion and fine particle size reduction, homogenization of fillers and raw materials, attrition and pulverizing applications in ball, vibro, dyno, pearl, bead, pebble, …
High-chromium cast irons are commonly used for industrial applications where excellent wear and abrasion resistance along with an ability to withstand moderate impact is required [].Applications include mineral processing, cement manufacturing, slurry pumping, grinding balls and liners.
The invention discloses an ultrahigh chromium grinding ball and a processing process of the ultrahigh chromium grinding ball. A metal material which is appropriate in chromium content and low in carbon content is selected to ensure the chromium-carbon ratio to be about 7-10, so as to obtain metallographic structures of martensite (M), alloy carbon compound (M7C3) and …
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.
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 ...
3.1 Matrix structure (1) Carbide and Martensite. The microstructure of the chromium grinding balls are mainly carbide, and the carbide of high hardness in white cast iron is Fe3C, Cr3C, (Fe, CR)3C, Cr7C3, Cr22C6, WC, TiC, etc., therefore, the size, number, distribution, shape of the grinding ball has a direct impact on the performance.
