where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

Normally, when the ball mill grinder is running, the temperature rise of the main bearing does not exceed 55℃, the temperature rises of the transmission bearing and reducer do not exceed 55℃, and the maximum temperature rise does not exceed 60℃.
The High Energy Ball Mill E max from Retsch achieves fine particles in the nanometer range through high friction and impact, while maintaining a narrow particle size distribution through thorough sample mixture. This mill not only reduces grinding time, but also removes the need to cool down. The High Energy Ball Mill E max can be used across various application fields including agriculture ...
The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. 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 minor warming effects. These ball mills are also suitable for mechano chemistry.
