Haoyang Hi Chrome Grinding media balls can provide: Cr 1%-28%, hardness: HRC40-66, Dia.10mm-150mm alloy cast steel balls. The balls have a lot of excellent properties, such as higher hardness, good abrasive resistance, together with a good surface finish and small dimensional allowance after scientific heating treatment, as one type of chrome grinding media, it can be widely used in ball mill grinding systems of mines, cement, building materials and chemical industries,etc.

High Chrome Casting Grinding Balls：

In high chrome casting grinding ball, chrome concentration is ≥ 10% - 14%, hardness ≥ HRC58. High chrome casting grinding ball is one of the wearable steel ball with better performance-price-ratio, and its extensive usage has won itself a high share in the market.

 Middle Chrome Grinding Balls:

In middle chrome grinding balls chrome concentration is ≥ 7-10%, hardness ≥ HRC 48, Middle chrome grinding ball have a better performance than complex alloy ball.

Low Chrome Grinding Ball:

In low chrome grinding balls chrome concentration is ≥ 1-3%, hardness > HRC 45, This wearable steel ball is called low chrome grinding balls, which is made by smelting in intermediate frequency electric furnace, metal mould or sand casting process. It applies to metallurgic mines and slag industries where no high grinding accuracy or wearability is required.
