As shown in Fig. 2 a–c and Table S1, the average particle size (D 50) of the G-2 has almost no change, whereas the distribution of the small-size particles increases compared with the original spherical natural graphite, which indicates that part of the particles begins to refine in a short milling time.The average particle size decreases …
Silica (SiO2) is considered as a promising candidate anode material for next-generation lithium-ion batteries (LIBs) owing to its low cost, abundant reserve on Earth, and relatively high theoretical specific capacity. However, the development of SiO2-based anode materials has been impeded by their poor electrical conductivity and sluggish …
The metallurgy of the lifter bars must be carefully matched to the grinding application. In mills with high impact such as large SAG mills, a high impact resistant Cr-Mo steel is required. In applications of low impact, the more abrasion resistant, castings such as Nihard are utilized to achieve maximum life through high abrasion resistance.
