All the specifications of the grinding rod products are superior to other similar products in the market. And it is fully accepted and satisfied by our clients.

Brief Introduction of Products

Houde is specialized in manufacturing rolling forged grinding balls ranging diameter from Φ 20 to Φ 150mm.

Houde Grinding Balls have following advantages: Precise dimensions, spherical geometry, high throughout hardness and outstanding mechanical performance. Meanwhile, the characteristics: Excellent wearability, permanent in shape and cracking-proof ensure our balls could be well and widely used in large-scale mines, power plant, cement plant and the other industry. Our balls have gained good reputation in both domestic and international mark due to the fact that using Houde' S grinding balls can reduce the usage of grinding balls, improve the fineness of slurry, and therefore improve productivity of communition and flotation process.

The major advantage of rolling forged balls, compared with traditional up-set forging grinding balls, is high stability, and the difference between surface and core have been minimized, which leads to a result that the uniformity of slurry can be improved and therefore communition and flotation productivity can be improved. A unique feature of the HOUDE manufacturing process is on-line heat-treatment favilities, which is self-designed and ensures our technology in leading position in the world.

Derailed properties are as follows:

1. High throughout hardness: The surface hardness could be HRC 60-65; The average volumetric hardness could be HRC 60-65.

2. AK>=12J/cm² .

3. Good ductility and none breakage: Our drop balls test result shows 100% better than national standard.

4. No loss of roundness: In the mill, Houde balls won' T be out of round from start to finish.
