the rate of grinding in the planetary ball mill is known to be about 100 times greater than that in a tumbling ball mill and about 50 times greater than that in a stirred ball mill2). Another result is given in Fig. 3, from which it is seen that even small glass beads with a low density can be used to grind hard materials

The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area. Additionally, the attritor mill works at a higher rotation speed up to SPEED.
The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these …
Mixer Mill MM 500 control. The MM 500 control is a high energy laboratory ball mill that can be used for dry, wet and cryogenic grinding with a frequency of up to 30 Hz. It is the first mixer mill in the market that allows to monitor and control the temperature of a grinding process. The temperature area covers a range from – 100 to 100 °C.
a Reaction conditions: a mixture of 1a (0.369 mmol), 2 (0.369 mmol) and eosin Y was mixed in a 25 mL PMMA milling jar with 15 ZrO 2 balls of 5 mm in diameter at 25 Hz. b Determined by 1 H NMR spectroscopy. c A 25 mL Teflon milling jar was used. d 1a, 2 and the PC were mixed for 30 s in the PMMA jar, then the mixing was stopped and the milling jar was …
Proof of principle in the MM-500: 241 mg (1.10 mmol, 1.5 equiv.) PMDA and 259 mg (0.73 mmol, 1 equiv.) TAB were placed in a 50 mL zirconia milling jar with 22 zirconia milling balls of 10 mm diameter followed by 3.5 g of sodium chloride. The reaction mixture was then placed in the holders of the RETSCH MM500 and was mixed at 25 Hz for 20 min.
Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent.
