· The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
· Horizontal milling machines feature short and thick tools capable of removing large amounts of material from the workpiece compared to the vertical milling machine. Vertical milling machines feature long and thin tools. The difference in cutting tool geometry affects the nature and accuracy of the cuts each machine is capable of.

¾Although vertical axis wind turbines have these advantages, their designs are not as efficient at collecting energy from the wind as are the horizontal machine designs. ¾There is one more type of windmill called Cyclogyro windmill with very high efficiency of about 60%. However, it is not very stable and is very sensitive to wind direction.
· Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
· Vertical milling is an excellent choice for projects mostly worked on a single side, such as sinking dies and working with large metal plates. In some cases, vertical mills are simpler and less complex internally than horizontal mills, because the spindle doesn't have to be geared to move in two directions. Some vertical milling projects are ...

The velix ® is most commonly placed downstream of either a tra ditional horizontal ball mill or, more recently, polycom ® highpres sure grinding rolls (HPGRs). The product exiting these mills is first fed into a slurry tank 1. The fresh material is pumped to a hydro .
Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter ( Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Horizontal bead mills or agitator ball mills with a horizontal grinding chamber do not have these advantages and are thereby disadvantageously designed and built. High Performance Because of VOLLRATH's unique square shaped (with rounded corners) grinding chamber and special grinding discs, a very high turbulence and torque is transmitted between the discs, the mill base/beads mixture .
