After milling for min, the length decreases from 10 to 4 μm, and the length distribution ranges from 1 to 8 μm owing to the shear forces applied by the threeroll mill. The length is decreased to μm by increasing the milling time to 3 min, and most of the CNTs are shorter (3 μm) than those obtained by min of milling.

All samples were passed through the mill 6 times. The roller distance was gradually lowered from initially 25 μm in the first cycle to 5 μm in the final cycle. Despite cooling at − 23 °C a good share of THF evaporated in the course of threeroll milling (1 h) and highly viscous dispersions were obtained which were predried in a vacuum ...

This machine consists of three rolls each of which has a different revolution speed. Material is processed by the compression effect produced by the pressure between rolls and by the shearing effect produced by rolls with different revolution speeds. Three Roll Mill is best suitable for processing materials with medium to high viscosity.
