3/2/2012· PbO powder could be pulverized to ∼100 nm for 1 h milling while the surfaces of the powder particles were modified with LDPE simultaneously. By wet milling of PbO, pulverization as well as simultaneous surface treatment was possible, while the layer of the methylene groups on the surface of PbO contributed to the prevention of agglomeration between PbO particles.

the main reasons to granulate powders is to make them more compressible. Wet granulation When powders are very fine, fluffy, will not stay blended, or will not compress, then they must be granulated. Fluffy is not a tech-nical term, but it fits the problem well; it means that the re-quired quantity of powder physically will not fit into the die

With an increase in ball milling time, DAV decreases from 60.1 to 35.5 µ m. When the ball milling time is 50 min, DAV reaches the minimum value of 35.5 µ m, a 41% decrease compared with the value before ball milling. When the ball milling time exceeds 50 min, DAV fluctuates with a variation of ∼3% (Figure 9 (d) ). 3.3.2.
