Bead Mills are machines for dispersion processing, where solid particles (pigments, fillers) are reduced in size and finely dispersed and wetted out in a liquid phase. Small ceramic, glass or metal beads are agitated inside the mill chamber to aid particle size reduction through impact and energy input while the dispersion is pumped through the
fines out of the mill and reduce the overall residence time in the mill. This will result in a coarser grind with a slightly steeper particle size distribution curve (see Graph 4). If one increases the density, the pulp will become too sticky and the ball charge expands. The balls become coated and the grinding efficiency decreases. The pilot
A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them
