Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and therefore short grinding times.
The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls. To achieve this, the grinding jar, containing the material to be ground and grinding balls, rotates around its own axis on a main disk whilst rotating rapidly in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to separate from the inner wall of the grinding jar. The grinding balls then cross the jarat high speed and further grind the sample material by impact against the opposite jarwall. In addition, impact between the balls themselves on the sample material adds to the size reduction process.
Please note: For the Planetary Mill, you require 2 or 4 grinding jar of your choice and the corresponding number of grinding balls. The grinding jar material must also be harder than the material to be ground. In normal cases, grinding jars and balls of the same material are used. To shorten the grinding time, larger or heavier grinding jars and grinding balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the jar volume!
Anodontia (also known as Hypodontia) is a condition where some teeth never grow in place. Depending on how many teeth are missing, dentists either treat it with implants, dentures, or simply shifting teeth over to fill in the gap.
This condition involves a talon-like protrusion that grows at the back of a childs tooth. It usually occurs behind incisors or canines. These protrusions can cause problems such as a misaligned bite, irritation of the mouth, and even plaque buildup.
Just as theres a condition of not having enough teeth, theres also a condition of having too many teeth. This is called Hyperdontia. Hyperdontia usually involves only one extra tooth, but it can be more. These teeth rarely erupt and usually develop inside the gums, which can cause all sorts of crowding and misalignment with other teeth.Get in Touch with Mechanic
