Traditional ball mills and vertical mills are generally limited to a finished particle size of approximately 5 microns, which can be achieved only with great attention to media size. Grinding media for ball mills ranges in size from 6 - 10 mm for most traditional applications and 1.5 - 2.0 mm for vertical mills.

The typical configuration of the ZM 200 for grinding powder coatings is: 12-tooth rotor of stainless steel; distance sieve 1.0 mm, 0.75 mm, 0.5 mm, 0.25 mm or 0.2 mm; feeding kit DR 100; cyclone with 3 L or 5 L receptacle. In most cases, sample batches produced in the rotor mill will contain some larger particles that can be easily removed …
High-speed dispersers are mechanically simple, easy to operate and formulate for. Cycle times for pigment dispersion are typically 30 to 60 min., followed by a 15- to 30-min. letdown. With short cycle times, these dispersers are well suited for the rapid production of paint based on inorganic pigments.
Two new grinding beads are available that are made from high-strength forms of zirconium oxide. The two materials, zirconia-toughened alumina and rare earth-stabilized zirconia, offer mill operators long bead life, low mill wear, attractive pricing and densities to cover almost any milling range.
Part 1 of this series (see the April 2008 issue of PCI) detailed the main considerations of bead density effects on mill operation and efficiency. ... Grinding, or de-agglomeration, is affected by impact, pressure and shear forces between the grinding media and the mill parts. In each situation there is a critical energy required to break ...

The laboratory Perl Mill (r) PML-H/V MegaTex (r) for fine grinding of paint, lacquer, ink and pigments works with various types and sizes of grinding media. Modular process units permit the research of application-specific parameters. The grinding chamber is coated …
Dispersing Without Grinding Media. May 1, 2015. A crushing or dispersing process is required in the manufacture of many different products. For some applications with the goal of achieving deagglomeration, disaggregation or delamination, manufacturing technologies are often applied for which optimization is both desired and necessary.

Air in the dispersion causes many problems in the mill, such as high temperature due to poor heat transfer, inefficient grinding due to micro bubbles inhibiting the contact of the grinding media and thixotropic viscosity preventing efficient bead separation. If this dispersion sits around for a week or so, it will deaerate.
New Materials for Micro-Grinding Beads. June 1, 2005. Ceramic media are well established as the most highly efficient media for micro-grinding and micro-dispersing. High bead wear resistance is most often considered the leading parameter for the choice of media, because it delivers the most significant value to users: low cost of media;

DCP-MEGAFLOW-C® mills were designed for high-energy density grinding and dispersing applications. Features include a modified rotor/stator design with better grinding zones; a modified double-cylinder design for improved residence time distribution; and a recirculation design that offers higher flow rates.
DIFFERENT MILLS REQUIRE DIFFERENT AMOUNTS OF MEDIA •BASED UPON WORKING VOLUME OR TOTAL VOLUME •Mills such as the Immersion Mill have a fixed amount determined by size of the basket •Steel Ball Mill 33.3% •Open Head Sand Mill 35-45% •Ceramic & Pebble Ball Mill 50% •Dry Grind Batch Attritor 45-60% •Wet Grind …
The fineness of the processed material depends on the time the material stays in the grinding chamber ("dwell" time). Dwell time is controlled by the pumping rate. The slower the pumping rate, the longer the dwell time and the finer the grind. The grinding media used in continuous grinding mills range in size from 2mm to 10mm in diameter.
