Improvements in the yield stress and Young's modulus of the MDPE/CNT composites were also observed. This was ascribed to the uniform distribution of CNTs throughout the polymer. Terife and Narh [158] reported the preparation of LLDPE/CNT by means of cryogenic ball milling. The effects of the milling time and ball size on the morphology of the ...

Dispersion of carbon nanotubes and carbon nanofibers is a crucial processing step in the production of polymerbased nanocomposites and poses a great challenge due to the tendency of these nanofillers to agglomerate. Besides the wellestablished threeroll mill, the ultrasonic dispersion process is one of the most often used methods. It is fast, easy to implement, and obtains considerably good ...

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].

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.
