In the present work, we have investigated the role of calcination temperature in altering the structural, optical and antibacterial properties of ball mill synthesized Co3O4 nanoparticles. The outcomes of Xray diffraction patterns and their Rietveld refinement confirm the presence of spinel cubic phase of Co3O4 and lattice expansion with increase in calcination temperature. The crystallite ...

In the field of Lead processing, Dry type Ball Mills are used for conversion of Lead pellets into fine Lead Oxide Powder (Lead Oxide + Free Lead), also commonly called Grey Oxide due to its appearance. The Ball Mill with its preparatory and collecting equipments is therefore also called a Grey Oxide Plant. Description of Process

For mechanical milling, a shaker, ball, or mill have generally used at various frequencies from 5 to 60 Hz (Stolle et al. 2014). Common grinding and milling apparatus were shown in Fig. 2. The disadvantages of hand grinding are open and sensitive to environmental factors, while mechanical milling presents an enclosed solventfree medium.

Barton pot: A fine stream of molten lead is inserted into a heated vessel. Each droplet reacts with the air to form an oxide layer, giving 70 85% lead oxide. Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 80% lead oxide.

As the rotation speed of the highspeed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is [49, 50]. The parameter setting of the ball mill is shown in Table 1.

The benefit of ball milling is its ability to reduce particle size without changing the particle's shape by optimizing the milling time, balltomaterial ratio and milling speed [20]. Since Bi 2 O 3 is a highly brittle metal oxide and significantly susceptible to particle breakage, the ball milling conditions were optimized to obtain particles ...
