Size Reduction - Visual Encyclopedia of Chemical .

Size reduction in attrition mills occurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer level. General Information The most commonly used attrition mills are ...

Colloid Mill: Operating Principles, components, .

Colloid mill is a machine used in the disintegration of solid particles or droplet size of a liquid present in suspension or emulsion. The machine consists of an inlet (which is subjected to a tremendous shearing action that effects a time dispersion of uniform size) and an outlet. Colloid mill works on the rotor-stator principle. The equipment breaks down materials by forming dispersion of ...

Bead Milling | Material Milling | Dispersion .

What is Bead Milling? 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 mill.

Since the kinetic energy of the balls is a function of their mass and velocity, dense materials (steel or tungsten carbide) are preferable to ceramic balls, and the size and size distribution should be optimized for the given mill[5]. Too dense packing of balls reduces the mean free path of the ball motion, while a ...
