No eco-friendly grinding method available. You may use green synthesis instead by say bioreduction.

Dear Dr. Shrikaant Kulkarni

Thanks so much for sharing your answer. Could you please provide any reference?

My regards,

Dear Dr. Heba Y. Elbasiouny,

The ball milling is an environmentally-friendly, cost-effective technique. The ball mills can be divided in two groups: direct and indirect milling. In the first case rollers or mechanical shafts directly act on the particles and transfer the kinetic energy. In the second case the kinetic energy is firstly transferred to the mill body and then to the grinding medium. These ball mills are the most widely used in the field of cellulose and they can be further divided into three groups: tumbler ball mills, vibratory mills and planetary mills. In vibratory mills the vessel containing the sample and the grinding medium are shaken back and forth at high vibrational frequencies. Important factors are the vibrational frequency, the amplitude of vibration and the mass of the milling medium. The size of the vessel is an essential parameter for the efficiency of the process as a higher distance allows a higher kinetic energy and therefore stronger impacts.

Best regards,

Igor Novak
