Lubrication system is in the key part to reduce mechanical wear and tear, including the ball mill. Generally, you should replace all the old lubricating oil and clean the machine thoroughly after the mill was put into work as long as one month. After that you should change the lubricating oil about every six months for each time.

Among different approaches for fabricating hybrid nanocomposites, ball milling is a simple, low cost and high yield method. Also, it is an efficient way for producing CNT strengthened alloys due to the possibility of dispersing carbon nanotubes as reinforcement elements in metal matrix composites [10,13,14].

Ball milling of carbon nanotubes (CNTs) in the dry state is a common way to produce tailored CNT materials for composite applications, especially to adjust nanotube lengths. For Nanocyl TM NC7000 nanotube material before and after milling for 5 and 10 h the length distributions were quantified using TEM analysis, showing decreases of the mean length to 54% and 35%, respectively.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
