One-Piece Ceramic Mills provide one of the most efficient methods of wet or dry milling of solids in a low contamination environment. PAUL O. ABBE has been designing and manufacturing tumble mills for over 100 years for applications ranging from ceramic glaze and semi-conductor materials to rare earth metals and pharmaceuticals. Advantages of Tumble Milling: ► FINE PARTICLES & NARROW DISTRIBUTION - Tumble milling takes place over a controlled period of time and results in both fine particle size and narrow size distribution. ► MILL & DISPERSE - When wet milling, solids are both size reduced and dispersed in the liquid medium. ► LOW TEMPERATURE - Tumble milling avoids temperature spikes by putting more energy into milling and less into unwanted frictional heat. ► LOW CONTAMINATION - The energy efficient impact of media results in less media-to-media friction and less product contamination. ► CONTROLLABLE - Variables including rotational speed, media size and milling duration can be independently controlled with predictable effects on milling results. ► PREDICTABLE SCALE-UP - Scale-up from small to larger mills is predictable. Tumble milling is one of the few unit operations that actually improves with increasing size.
