Product Description

Grinding media represents a large portion of the total grinding cost and has a significant impact on mining OPEX. Selecting proper grinding media with the best quality is the key to improving grinding efficiency and minimizing downtime. Whether you operate a ball mill or SAG mill, regardless of the wet or dry grinding environment, we can all select the most suitable grinding ball for you as per your specific application.

10+years of professional experience and advanced technology enable us to manufacture grinding balls with ultimate strength and toughness according to different material formulations. All FOCREA balls have been tempered to maximize their mechanical properties. HUAO balls are high-hardness from surface to the center, unbreakable, have no deformation, good for fine grinding and impact grinding.

The production process of the Steel forged balls

1.Raw material
All the material is qualified with certificate and made in the Chinese largest steel production enterprise.

2. Different steel specifications ccording to the clients's requirements.
Main Steel Material :C45 Steel;60Mn Steel;B2 Steel

3. Steel Cutting:
the steel bars should be cut into small pieces according to the size of steel balls required by the order.

4. Heating:
we use the electric furnace instead of the traditional coal stove, the biggest advantage is that all the steel bars can accept the most approriate temperature during the heating progress. It affect the hardness and toughness directly.

5. Hammer forging:
The raw material is forged to a certain deformation by the air hammer, when the compression ratio increased, the micro-structure become more compact so that the hardness and the toughness can be improved.

6. Heat treatment:
Both the water quenching heat treatment production line and our own temperature control technics are important.
We have mature production technicians responsible for the heat treatment process as we know this process affect the grinding balls performance directly.

7. Quality Control.
Raw material test before production
Hardness test Drop Test Impact Test Core pulling Test after production
SGS test before delivery
Certificate: ISO 9001:2008
