How Ball Bearings are Made Sheldon Brown

In his workshop for velocipedes, bicycles and tricycles he therefore worked intensively on the production of high-quality balls. The marble ball mills described above were probably not the model for Friedrich Fischer's ball milling machines. He developed, however, a similar production method (Figure 35, below).

Through the ball mill, we can get different sizes of hydrogenated titanium.

Multi-hydride systems with enhanced UCL Discovery

A two-step ball-milling method has been provided to synthesize Mg(BH 4) 2 using NaBH 4 and MgCl 2 as starting materials. The method offers high yield and high purity (96%) of the compound. The as-synthesized Mg(BH 4) 2 is then combined with LiAlH 4 by ball-milling in order to form new multi-hydride systems with high hydrogen storage properties.
