Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 115 times the shell diameter of the powder particle arrangement that is on the topology of the contact network and on the physical and chemical properties of powders Martin et al 2003 Ball mill.
Common methods of synthesis of ferrofluids employ coprecipitation 10 ball milling 11 solgel method 12 and micro emulsion 13 among these methods coprecipitation is the low cost and less energy required for synthesis of ferrofluids 2 sample preparation the chemical coprecipitation method was used to synthesize co 1 xzn xfe 2o.
