NETZSCH Taurus Ball Mill, the pinnacle of fine and ultra-fine grinding technology. Achieve precise particle sizes with durable, low-maintenance equipment.
Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill and …
The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding bowl respectively the mortar. The grinding can be performed dry or wet. In addition to comminution Ball Mills are also the ideal and reliable lab assistants for mixing and homogenising.

Another rule of thumb is, that the grinding balls should be at least three times bigger than the largest sample piece. In this way it is ensured, that the balls can pulverize the sample quickly. To find the suitable ball size for the desired final fineness, usually a factor of approximately 1000 can be applied. If a grind size of 30 µm (D90 ...
DescriptionTungsten carbide grinding media balls are the highest density media material for milling and crushing applications.Available as sintered rough balls (balls ...
To ensure that the grinding balls rapidly pulverize the sample, they should have at least three times the size of the biggest sample piece. Typically, a factor of approximately 1000 can be applied to ascertain the suitable ball size for the intended final fineness. If a grind size of 30 µm (D90) is the objective, ball diameters between 20 mm ...
