Ball Milling Theory Introduction: Figure 1: Ball milling terminology. I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks. Being a scientist who had experimented with the ancient recipe himself during his youth, he thought I should try making my own fireworks.

has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill circuit feed size (x. 2) in open circuit requires specific energy equivalent to:

A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8. Estimate: 1.

The equation for this potential energy (U) is. U = mgh. where m is the mass of the pendulum bob, g is the acceleration due to gravity, and h is the bob's height, measured from some arbitrary reference point. If the pendulum is swinging, it also has kinetic energy. The equation for kinetic energy (T) is. T = (1/2)mv 2

This equation tells us how the batted ball velocity (v 1a)depends on the mass of the ball (m 1) and bat (m 2), the elasticity of the ball (e), the pitched ball speed (v 1b) and the bat swing speed (v 2b). The properties of the ball may be treated as constants since they don't change during a turn at bat.
