How Ball Bearings are Made - Sheldon Brown

Who knows why steel balls were not machined, from the very beginning, to a principle similar to that of stone ball production. This production method guarantees for a large number of balls equal diameters when machined between two plates, since only the ball contacting the upper and lower rotating surface simultaneously with a certain load can ...

Different Types of Balls: Mass, Elasticity, and Friction ...

Not all balls are equal. Mass and elasticity affect how high the ball will bounce, and how far it will travel. So does the friction of the surface on which the ball lands. This lesson compares the bouncing of a bocce ball, a tennis ball, and a golf ball. Even a hard rubber ball won't bounce, if .

Drag of a Sphere - Glenn Research Center

May 05, 2015 · Drag for a rough surface ball is shown on the figure at the top of the page by the dashed line. This effect produces a rather interesting result. There is a small range of Reynolds numbers for which the drag of a roughened ball is less than the drag of a smooth ball for the same diameter, velocity and flow conditions.

Factors Affecting Ball Mill Grinding Efficiency

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
