VIBRO ENERGY MILL Filed Aug 27 1963 2 Sheets Sheet 2 P 3 263 177 Ce Patented August 23 1966 3 268 177 VEBRO ENERGY MILL Richard K McKihben La Canada Califi assignor to Southwestern Engineering Company Los Angeles Calif a corporation of California Filed Aug 27 1963 Ser No 304 832 6 Qlaims Cl 241 475 This invention relates to vibro energy mills that is to mills which are vibrated at high frequency to perform grinding deburring polishing and similar operations.
First to provide a vibro energy mill in which the mill chamber is annular in form and incorporates a rotary vibrator rigidly connected therewith the mill chamber being supported by a set of springs located within the annulus formed by the mill chamber and in proximity to the vibration null point established when the mill is vibrated.
Second to provide a vibro energy mill which by reason of the fact that the mill chamber is spring supported in proximity to the vibration null point operates essentiallyas if it were freely suspended and transmits a minimum of vibration through the springs to the supporting structure.
Third to provide a vibro energy mill wherein the motor drive is independent of the mill and free from the vibrations produced thereby and which is connected to the mill by a drive means passing through the vibration Illllil point so that the drive means is not adversely afiected by vibration of the mill.
Fourth to provide an annular vibro energy mill which is spring supported near its upper end from a central tubular pylon and which incorporates a novelly arranged rotary vibrator rigidly connected to its lower end and iocated within but clearing the walls of the pylon so that the vibrator is in coaxial relation to the pylon for drive connection to a motor supported directly on the pylon.
Optimised grinding process via torque optimised frequency converter In the Vibrating Cup Mill the grinding is performed by horizontal circular oscillations of the grinding set on a vibrating plate The grinding set consisting of ring and puck comminute the grinding sample with extremely high pressure impact forces and friction.
FIG 1 is a longitudinal sectional view of the vibroenergy mill.
