Low chrome casting grinding ball is widely used in cement, metal mining, power plant and chemical industry etc.. The hardness reaches up to 47HRC(the surface and inner hardness tolerance with in 2HRC), which makes the wear-resisting property much better than forged ball, in addition, the distribution of the hardness gradient is average. The property- low wear rate, good toughness and less breakage, prolongs its life, improves the productivity of the ball mill, and lowers user’s cost. Our quality is accord with GBT17445-2009 China national standard.

Grinding Media is widely used in cement, metal mining, power plant and chemical industry etc. The hardness reaches up to 66HRC(the surface and core hardness tolerance could be controlled within 2HRC),which makes the optimum wear resistance against abrasion and corrosion. 

There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time.

The choice of grinding media Spec is determined upon:

1.The mineral ground 

2.The mill data and liner used 

3.The wear mechanical (Impact ,Abrasion ,Corrosion)

Based on our world wide experience, H&G can help select optimum alloy for specific application ranging from Chromium 10 to 26% and Hardness ranging from 58 to 66 HRC.

The balls can be classified in 6 main categories, each of which has a particular field of Mining Application.

  The choice of the Spec is determined upon:

1. The mineral ground

2. The mill data and liner used

3. The wear mechanical ( Impact , Abrasion ,Corrosion)
