INTRODUCTION
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...

power (W in Watts) proportional to the vibrating area S and the mean square vibrating velocity < v 2>, given by; WcS=ρνσrad 2 where is the air density (kg/m3), c is the speed of sound (m/s) and rad is the radiation efficiency (see Gerges 1992). Therefore care must be taken to reduce the vibrating area and/or reduce the vibration velocity.
One rule of thumb is to always choose the smallest possible nose radius to reduce vibration tendencies. When it comes to point angle, there are two paths to choose: A small insert point angle will improve tool stability, give good clearance of a trailing surface, and small chip area variations if the tool starts vibrating in a radial direction
