Magnetic shaft coupling transfers torque from one shaft to another, but using a magnetic field rather than a physical mechanical connection. It’s mostly used for liquid pumps and propeller systems, since a static, physical barrier can be placed between
For fine grinding, the performance of the grinding machine is important, but the quality (high hardness, high density, high wear-resistance, high strength, and size distribution) of the grinding media, which is charged into a grinding machine to play the
