Different types of highenergy ball mills have been developed, including the Spex vibrating mill, planetary ball mill, highenergy rotating mill, and attritors [50]. In the nanotube synthesis, two types of HEBM mills have been used: a vibrating ball mill and a rotating ball mill. Contact Supplier
It is highly energetic compared to the attrition and vibratory mills. A given reaction can typically take place an orderofmagnitude faster in the SPEX mill than in the typical attritor or vibratory mill. Planetary ball mills have also often been used for research studies (see Fig. 4: a modified Retsch Planetary Ball Mills, PM 400[28].

Aside from common ball mills there is a second type of ball mill called a planetary ball mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a socalled ...
The range of highenergy ball milling equipment divides, approximately, into two categories: small, highenergy laboratory devices, and larger facilities capable of milling commercial quantities of powder. The former category includes SPEX shaker mills and planetary ball mills.
The ball velocity and energy input from balls to powder are given in Table 2. Higher ball velocity in Spex mill led to higher impact energy in comparison with two other mill machines. Total energy input to the powder in highenergy planetary PM100 mill is higher than Spex shaker mill because of higher

A variant of the rotating (or tumbling) ball mill is the planetary ball mill. This variant imparts a higher degree of energy in an attempt to create finer or more homogeneous powder size distributions. Instead of relying on gravity to accelerate the balls, the mill chamber is placed offcenter on a rotating platform.
Planetary Mills are ideally suited for fine grinding of hard, mediumhard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls.
