High energy ball milling process for nanomaterial synthesis

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling balls in the bowl.

The Awesome Foundation : Capturing Pinball Physics

Torque, friction, tension, magnetic force, electrical forces and gravity all happen on the pinball playfield. Patterns in collisions of the pinball off the surfaces, bumpers, flippers, slingshot rubbers, are harder to see because the ball is moving so fast. Capturing Pinball Physics is working on a way to slow down ball collisions so the patterns of interaction are easier to observe.

May the Force Be With You!

The simple machine lets you use a smaller force over a greater distance to lift the chest. The more force applied to an object, the greater the change in the object’s speed. If you want to throw a fast ball, you must throw as hard as you can. If you want to swim fast, you apply as much force …

At the sharp end - a guide to CMM stylus selection

The two most common ball specifications used are grade 5 and grade 10 (the lower the grade the better the ball). ‘Downgrading' from a grade 5 to a grade 10 ball saves a little in terms of the cost of the stylus, but may be enough to threaten the 1:5 ratio.
