The use of ball milling to obtain cellulose nanocrystals was also explored by the group of Yu who extracted CNCs from ballmilled wood via a multistep process 40 DouglasFir wood chips were firstly hammermilled to wood flours which were then treated using a planetary ball mill at 270 rpm This process was followed by enzymatic hydrolysis.
The noise of ball mill is also a difficult problem Ball mill as one popular grinding equipment commonly used in chemical industry metallurgy mining and other industries in the process of production its minimum noise is 95 dB A up to 120 dB A which is one of the strongest noise in industrial production and it must be controlled.
Ball mill operation is often regarded as something of a mystery for several reasons Ball milling is not an art its just physics The first problem will ball mills is that we cannot see what is occurring in the mill The other problem is that many of the independent variables.
