ADJUSTMENT OF THE WEIGHTS CHANGES AMPLITUDE
PRESENTLY WIRED FOR 3/60/460 VOLTS
"HIGH FREQUENCEY, LOW AMPLITUDE MOTION, AS EMPLOYED IN
THE VIBRO-ENERGY MILL, IS THE MOST EFFECTIVE METHOD OF
CONVERTING ENERGY TO ACCOMPLISH PARTICLE SIZE REDUCTION
FROM 100-MICRON TO SUBMICRON RANGE".
"THE ABILITY TO CONTROL PARTICLE SIZE PRECISELY IS VERY
IMPORTANT IN MOST INDUSTRIES PROCESSING FINELY GROUND
MATERIALS. THE VIBRO-ENERGY MILL IS UNEQUALED IN THIS
IMPORTANT ASPECT OF GRINDING TECHNOLOGY. THE USE OF
ALUMINA CYLINDERS COUPLED WITH THIS UNIQUE MOTION CAN
PROVIDE A UNIFORM PARTICLE SIZE & DISTRIBUTION".
"LOW MATERIAL CONTAMINATION - DUE TO RAPID WEAR OF THE
GRINDING MEDIA IN BALL OR PEBBLE MILLS, THESE MACHINES
CANNOT BE USED IN MANY APPLICATIONS. IN CONTRAST,
VIBRO-ENERGY MILLS INTRODUCE NEGLIGIBLE MEDIA & LINING
CONTAMINATION, DUE TO THE SMALL IMPACT FORCES GENERATED".
"REDUCED ELECTROSTATIC CHARGING OR AGGLOMERATION DURING
GRINDING. PIGMENTS PRODUCED BY PRECIPITATION & FILTRATION
FREQUENTLY AQUIRE ELECTROSTATIC CHARGES DURING THE PROCESS.
THESE CHARGES BOND THE PIGMENT PARTICLES VERY TIGHTLY,
SLOWING DOWN CONVENTIONAL GRINDERS. THE HIGH FREQUENCY
IMPACTS IN A VIBRO-ENERGY MILL QUICKLY DISSAPATE THE SMALL
STATIC CHARGES ORIGINALLY EXISTING IN THE PIGMENT".
"THE USE OF CYLINDRICAL GRINDING MEDIA, COUPLED WITH THE
UNIQUE VIBRO-ENERGY MOTION, ENABLES NARROW PARTICLE SIZE
DISTRIBUTION. THE VIBRO-ENERGY MILL NORMALLY USES SMALL
ALUMINA CYLINDERS DESIGNED TO ACHIEVE A COMBINATION OF
POINT, LINE AND FACE CONTACT. WHEN TWO PIECES OF
CYLINDRICAL GRINDING MEDIA ARE VIBRATING AGAINST EACH
OTHER, THE LARGE PARTICLES WILL BE WORKED ON FIRST,
AND REDUCED IN SIZE, WHILE THE SMALLER PARTICLES WILL
REMAIN PROTECTED. WHEN THE LARGER PARTICLES ARE REDUCED,
BY THE COMBINATION OF POINT, LINE AND FACE CONTACT, TO THE
SAME SIZE AS THE SMALLER ONES, CLOSE PARTICLE DISTRIBUTION
HAS BEEN ACHIEVED. FURTHER SIZE REDUCTION MAINTAINS THIS
