Shaker mills such as SPEX mills (Fig. 3a), which mill about 10 ±20 g of the powder at a time, are most commonly used for laboratory investigations and for alloy screening purposes.
The objective of the present work is the comparison of two common milling methods for the production of complex metallic alloy nanoparticles. γ-Al 12 Mg 17 nanoparticles were fabricated using both a planetary ball mill and a SPEX mill. The produced nanoparticles have been compared on the basis of the phase and microstructural characterisations by means of X …

shaker mills, planetary ball mills, attritor mills and commercial mills. 2.1.3.1 SPEX Shaker Mills SPEX shaker mills accept small amounts (about 10 – 20 g) of powder at a time. Due to their size and high energy, they are often used in laboratory settings. These mills commonly hold one vial, but new dual models can accept two vials at a time.
impeller cause to relative movement between balls and powders. In a planetary ball mill, a rotating disc and vials revolve in opposite direction in order of several hundred rpm. In a vibratory mill that also known as a shaker mill, the vessel is set in 1D or 3D vertical oscillatory motion. Spex 8000 is a commercial type of 3D vibratory mills.

In this paper, results are reported on the average ball temperature in a SPEX 8000 Mixer Mill and a Fritsch P-5 planetary mill. It is shown that while the temperature remains well below 100 C inside the shaker mill under typical operating conditions, temperatures much over 200 C are easily possible in planetary mills. Experimental details

The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only …
The ball temperature remains below 100 °C in a SPEX 8000 shaker mill and it is cooler when flat-ended rather than round-ended vial is used, although the milling intensity, as measured by the mechanical dose rate, follows the opposite trend. Temperatures over 200 °C are typical in planetary mills operating at similar milling intensities.
The mining and metallurgical laboratory, is a place in which mechanical and chemical working-tests are made on ores, fuels and furnace materials. It is of quite recent origin. The first laboratory of this kind to be used in connection with …
Balls either cascade or tumble during processing in these mills depending on rotational speed (see Fig. 3). The time taken to achieve MA scales approximately inversely to the size of the milling equipment used. Hence, milling which might take minutes to accomplish in a SPEX mill could take hours in an attritor or days in a horizontal ball mill.
