Steel Balls

why are swinging steel balls described as being Nearly elastic collisions?

It is very difficult to get elastic collisons because when balls hit each other some of the energy is used up as noise and heat. If you take your stell balls into a vacuum they should be better as no energy will be absorbed by the air molecules although there will be some heat in the balls after contact. Elastic collison requires conservation of the kinetic energy of the system. This happens only with sub atomic particles.

JOYAL Ball Milling

Working Principle Of Ball Milling:

 

Ball Milling can be divided into lattice type and overflow type according to different beneficiation methods, and this machine is two lattice-type ball mill. The materials from the feeding fittings enter evenly to the first bin of the milling machine via the feeding hollow axis when it works. There is a ladder-like or ripple-like scaleboard in the first bin, and different specification steel balls are installed in the bin. When the cylinder rotates and produces centrifugal force, the force carries steel balls into a certain height and then makes them fall to strike and grind the materials. After coarse grinding in the first bin, the material then enters into the second bin via a single layer partition board. There is a scaleboard and steel boards in the second bin, so the materials are further ground. In the end, the powder is discharged by output material board.
