Ball mill process characteristics

In the present work, the nanostructured Co-Cu powders with different Co/Cu ratio are prepared after 2-3 h of ball milling. As a precursor we use the Co/Cu composite powders with particles consisting of amorphous Co-P alloy core and Cu shell [3]. The structural and magnetic characteristics are analyzed for different Cu content and compared with the Co-Cu alloys produced by traditional mechanical alloying techniques. Also the aim of this work is to obtain additional information on Co-Cu alloy structure formed during the ball-milling process. 

After the above brief description of the two methods of leady oxide production the question arises logically as to which of the two processes is better. Table 5.1 compares the characteristics of the leady oxides produced by the Barton pot and ball mill processes [17].

Table 10.2 presents as an example the basic characteristics of zinc phosphate dried in a pilot spray dryer with reference to industrial standards (Lyulin, 1998). It is evident that pigments dried in a spray dryer with the shock-wave atomizer satisfy all requirements for the commercial product. In addition, pigments obtained with the shock-wave atomizer have a narrower size distribution so the throughput of the ball mills used in a downstream process of standardizing is increased by about 20% to 30%.
