  High chromium white cast iron grinding ball is also called high chromium alloy cast ball, high chromium steel ball, simply called high chromium ball. At present, most of the wear-resisting material enterprises in China take intermediate frequency electric furnace as the main body. The hot metal was microalloyed and tempered. Then add a unique metal mold, sand mold casting molding process; Then the matrix of martensite was obtained after high temperature quenching and tempering to achieve higher hardness and wear resistance.

  At present, most of grinding media used in cement industry in China are dominated by high chromium ball. With the continuous development of cement grinding process, the specific surface area and fineness of cement are required to be higher, so it is very important for cement enterprises to select the right abrasive materials.

  High chromium alloy casting ball is widely used in the powder preparation and ultra-fine deep processing of cement building materials, metal mines, coal slurry thermal power, chemical engineering, ceramic coating, light industry papermaking, magnetic materials and other industries. High hardness, low abrasion, good toughness, less breakage, in the use of the ball surface hardness will be further improved, wear resistance enhanced, can improve the mill production capacity, improve the specific surface area of cement and concentrate recovery.

  High wear-resistant grinding body, at the same time of the grading unchanged for a long time not only improve the grinding efficiency, reduce the time and the number of key down to fill the ball, also extend the clearance cycle, reduce labor intensity, to improve the grinding machine is used at the same time production, ensure the quality of abrasive, and reduce the power consumption and the consumption of grinding medium is of great significance. For example, the chromium alloy casting ball products developed by Anhui Ningguo Chengxin Wear Resistant Materials Co., Ltd. in combination with different industries and working conditions, in which the hardness of high-chromium ball forging specially used for cement grinding reaches over 62HRC (impact value ≥ 4.0j /cm2). In a number of large cement enterprises in China 4.2*13m cement mill use its tons of cement single warehouse consumption is only about 13 grams, compared with its wear resistance low chrome ball increased more than five times, for cement enterprises to create a value of economic benefits. It is the real environmental grinding ball and green grinding ball.
