Grinding Media
Ceramics, includes Aluminum Oxide and Zirconium Oxide (sp.gr. 3.5 to 6.1)
Alumina Grinding Media (sp.gr. 2.8 to 3.9)
Available in a range of specific gravities which rises as the alumina (Al2O3) content increases. The grinding media is actually alumina particles held in place by an SiO2 glass phase. Sizes from 400 microns to over 1 inch in beads, balls, satellites (ball with bands) and cylinders. Low to medium cost, small sizes are more costly.
Fused Zirconium oxide Grinding Media (sp.gr. 3.8) Smooth surface leads to low mill wear and longevity. Sizes from 200 microns to 2.5mm. Medium cost.
Sintered Zirconium silicate Grinding Media (sp.gr. 4.0-4.6) ZrO2 + SiO2 + Al2O3, with and without Y2O3 stabilizer. Tight size spreads from 200 microns to 2.6mm. Low to medium cost.
High density Zirconium oxide Grinding Media (sp.gr. 5.5) 95% ZrO2 + MgO stabilizer. Beads from 400 microns to 3.35mm. Cylinders and satellites to 1-1/4″. Medium cost.
Rare Earth stabilized Zirconium oxide Grinding Media (sp.gr. 5.8 to 6.1) ZrO2 + CeO. Yellow or black, very hard. Sizes from 400 microns to 2″. Medium cost.
Yttrium stabilized Zirconium oxide Grinding Media (sp.gr. 6.0) 95% ZrO2 + 5% Y2O3. Best wear properties of all grinding media, very round and very smooth, narrow size spreads. High cost is offset by low wear and minimal contamination.

Steel (sp.gr. 7.8)
Various alloys available (low carbon, high carbon, chrome steel, stainless steel, etc.) in a variety of forms:
Ball bearings Good wear, very round but will result in metallic contamination. Cost directly related to material and inversely proportional to size. 1/16″ to 6″.
Shot Irregular shapes with lumps and bumps, but only cost effective alternative for steel in sizes less than 1mm. Inexpensive, sizes from 90 microns to 3mm.
Other forms Steel wire can be cut and formed to produce diagonals, ballcones (looks like a flattened ice cream cone), pins (rods), oval balls and other shapes.

Glass (sp.gr. 2.2 to 3.0)
The first of the “engineered” class of grinding media, glass beads (small balls) and balls were developed specifically for grinding applications where sand wasn’t available. Glass is manufactured in various grades (Lead-free Soda Lime, borosilicate, low alkali, black glass, and others) in sizes from 1 micron to 2 inches.
Good wear properties coupled with reasonable roundness means this is the best material to start with when conducting grinding trials. Low cost.
Glass balls are also available in precision grades and are used in optical resolution systems and as “spacers” for precision electronics. Colored glass balls are used for both engineering and decorative applications.

Turbula Powder Mixer & Shaker
Turbula T50A – 55 Liter Powder Mixer Shaker
The mixing basket can hold up to 165 pounds in a 55 liter container. Special holders must be mounted for smaller containers. These inserts are custom designed to fit the dimensions of your mixing vessel. The movement of the mixing basket is controlled by a silent pendulum chain drive and the speed can be varied by adjusting the position of the V-belt on the 5-step pulley. An extra slow speed drive is used to bring the mixing basket into its loading position. A hand cart can be purchased to help with loading.
Turbula T10B – 17 Liter Powder Mixer Shaker
The mixing basket can hold up to 66 pounds in a 17 liter container. Twisted rubber clamping rings allow the use of smaller containers up to a maximum diameter of 220 mm. The movement of the mixing basket is controlled by a silent pendulum chain drive. The speed can be varied by adjusting the position of the round drive belt on the 4-step pulley.
Turbula T2F – 2 Liter Powder Mixer Shaker
The mixing basket can hold any form of container having a maximum volume of 2 liters. The containers are fastened in place by twisted rubber rings. The basket movement is driven by elastic drive belts and an eccentric drive gear. The speed can be varied by adjusting the position of the drive belts on its 5 step pulleys. The speed can also be adjusted optional frequency converter set up next to the machine.
The TURBULA® T2F used in all industries and application fields, especially in research, development, and analysis.
