Tumbling centrifuge

Particle Motion and Scale-Up Veiy little fundamental information is published on centrifugal granulators. Qualitatively, good operation rehes on maintaining a smoothly rotating stable rope of tumbling... 

Tumbling and centrifuging are batch processes, but all the others can be included in a continuous line process and, for suitable articles, the process can be fully automated. If the shape of the articles is unsuitable, some kind of hand spraying is usually selected. 

Another processing method has been termed the solventless. process. In this method, a premix is made from NC fibers plus liquid NG and minor ingredients dispersed in water. The paste is centrifuged and air-dried. The remaining ingredients are tumble-blended and then calender-rolled into sheets called carpet rolls . These are then extruded into finished pellets or cylinders...

After the item has been cleaned and treated, paint can be applied depending on the size, shape, complexity, and quantity of items to be painted, different application methods can be employed. When it is desired to paint a large number of very small items, the most commonly used methods are tumbling, barreling, or centrifuging. For all three methods, the parts are placed inside a barrel, solvent-based paint is poured onto the items, and the barrel is then rotated. After a short time and at the correct point of tackiness, the parts... 

Another type of miU commonly used in studies of mechanochemical processing is the planetary mUl. As implied by the name, the milling container is rotated about two separate paraUel axes in a manner analogous to the rotation of a planet around the sun. The miUing action of a planetary mill is similar to that of a conventional horizontal tumbling mUl. However, the velocity of the grinding media is not limited by centrifugal forces.
