Key properties of grinding media include composition, hardness, size and density. some common types include alumina, stainless steel, yttria stabilized zirconia and sand. ball milling will result in a ball curve particle size distribution with one or more peaks.
Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. during milling, the porcelain balls pulverized the materials into an incredibly fine powder.
Ball mills are used in chemistry and in industry to grind hard solids to a very fine powder. they are very similar to rock tumblers. basically, the idea is to rotate a container filled with heavy metal balls that crush the substance that you want to grind.
These ball materials are often used because they are inexpensive. nylon is one of the most common plastic ball materials. it is hard, it is tough and it is dense enough so that it sinks in water. nylon is slightly hygroscopic, so it isnt the best plastic to be used in water applications. ptfe. is a fairly common plastic ball material.
Loading of a ball mill by the material is proportional. the more material is fed into the mill the higher grinding productivity. but at some point there is too much material in the mill and the material is not grinded any more, the grinding productivity decreases abruptly down to zero and the mill blockage takes place see fig. 2. ...
