HIGH EFFICIENCY Due to the relatively slow rotational speed but large mass of media, more of the energy goes into millin Ceramic Lined Ball Mills Benefits of Tumble Milling: HIGH EFFICIENCY Due to the relatively slow rotational speed but large mass of media, more of the energy goes into milling and less wasted as heat.
Numerical modelling of highspeed ball end milling with
highspeed ball end milling of Inconel 718 using ABAQUS Explicit, and the simulation cost approximately 167h to complete one full revolution of the cutter. Many researchers concentrated mainly on the orthogonal cutting process using FEM , and the objectives of the studies were mainly on the effects of
Congratulations on your ball mill! You'll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.
High speed machining techniques can also be applied to contoured surfaces using a ball profile or corner radius tool. In these situations, the tool is not used in one plane at a time, and will follow the 3 dimensional curved surfaces of a part.
Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semiautogenous and autogenous mills

Ball Mill Critical Speed Mineral Processing Metallurgy
Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.

Carbide End Mills can run at higher speeds than highspeed or cobalt steel, it is also more resistant to wear and can be used at high cutting temperatures. Cobalt Steel End Mills resists abrasion and high cutting temperatures, and has higher feed rates than Highspeed Steel.
