Ceramic Beads and Ceramic Spheres

Two that I know. Smaller stuff look under spray drying. Larger "Ball Like" casting will be the more economic choice. The method for producing ball bearings is basically melting the ceramic it self and dripping the material from a spout or nozzle and allowing the surface tension to form the sphere. Here you will have a nice round and smooth ball to start with. Sizing and surface treatment are needed if these balls are to be used for bearing applications.

The ceramic industry forms "green balls" with a ball wrapping method that has the ability to form much denser beads or balls than pressing. The wrapping method virtually eliminates internal porosity.

Eirich (I have no connection to them but have used their equipment) is one of the International companies that makes ball forming "pans". This method yields a properly sized ball but one that is slightly irregular in shape. Typically this is the state at which they are fired.

These ball forming pans require auxiliary equipment. The ore is fed in dry and combined with a liquid in the pan.

Hi GUEST!

It's you again? First, let know about blackening metal, and only after, we can talk about spheres. However, if is possible to add little bit more information, will be appreciated, Gil again!
