Made of special metal materials, the mould is used to produce balls with the chilling forming technology.
Metal mold specifications

We also could manufacture according to customers requirement.
Grinding media ball mold is used to manufacture casting and grinding media ball. It is made up of two parts: one is the body of the mold, the material is ordinary cast iron; the other is the ball core, the material is high silicon heat-resistant cast iron. The same type of the ball core can be interchanged at will, and the ball core can be replaced after wear. The ball core can use up to 3000 times more.
1. Mould without ball core (25-120mm)
2. Mould with ball core (40-150mm)
The pictures of the above mentioned mould with ball core (also called ball bowl):
These moulds you can see are composed of the ball bowl and the body of the mould, the mould can be used for about 3000 times (GOOD MAINTANCE) before replacing the new ball bowl.
1. It adopts shock chilling method, which not only improve the hardness of grinding balls; make grain refinement but also make the same hardness for inner and surface. It improves the grinding balls wear resistant property.
2. Efficiency is high; usage cost is low. Get highly speak of from customers. Fully use the iron water (average 75% above), high production rate and longer life.
3. Easy operation. If the spherical core is abrasion. Change the spherical core, then it will a new mould. Save cost.
4. The grinding ball has good surface and no imperfection. It is the best choice to take the place of sand box mould.
Manufacturing and machining
It is used in the manufacture of wear-resistant grinding media ball.
1. Heating: it should be heated before using. When temperature is around 200-300 degrees, the mold can be casted.
2. Building: after heating, the upper and lower molds should be pour with sand (Noted :Jiangxi sand is the best). A hole is need in middle of sand mold with a tube as the inlet of molten iron after the upper mold finished.
3. Paint: after the sand-mold finished, the ball bowl(ball core) should be protected with acetylene through spay smoke (Note: It need protected after sand mold finished every time)
4. Casting: the mold should be closed after protecting. And immit the molten iron through the inlet pipe unit full.
5. Open mold: we should open the mold with two round bars respectively insert the holes on it, and get the balls out. Then re-mold and re-cast.
6. Sand ratio: 100kg sand equipped with 20kg clay and 8-12kg water glass, and the put them into milling machines to crush down.
1. We can customize according to your needs.
2. Technical support will be provided if needed.
3. Overseas service
