With the development of modern mechanical, aeronautic and astronautic industry, and the breakthrough of materials science, the ball bearings made from silicon nitride are widely used for high speed, high temperature, vacuum, radiation, running dry and strong erosion conditions because of their high-temperature resistance, erosion resistance, low expansion coefficient, low density, high hardness, etc.
The machining efficiency of ceramic balls is very low because the hardness of engineering ceramic materials is very high, and the materials are difficult to be machined, being a main reason that why the cost of ceramic balls is so high.
A diverging magnetic field is thus achieved in the fluid, which causes non-ferromagnetic materials (the balls and grits) to float.

The proto-machine-made sand is a new artificial material for environmental protection with grain size smaller than 5 mm made of water cleaned crushed stones or gravels broken and separated by machines, in which the stone powder maintains as prototype and certain content by improving the production technology.
Obviously, to ensure the clean crushed stones or gravels as raw materials of machine-made sand, the radical solution is to adjust the traditional water cleaning procedure to the first step for cleaning the crushed stones or gravels before broken.
