Theoretical probability is the likelihood that an event will happen based on pure mathematics. The formula to calculate the theoretical probability of event A happening is: P (A) = number of desired outcomes / total number of possible outcomes. For example, the theoretical probability that a dice lands on "2" after one roll can be ...

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.

Waves in which the medium moves at right angles to the direction of the wave. Examples of transverse waves: Water waves (ripples of gravity waves, not sound through water) Light waves. S-wave earthquake waves. Stringed instruments. Torsion wave. The high point of a transverse wave is a crest. The low part is a trough.

ball bearings can support axial forces in both directions as well as radial forces. Deep groove ball bearings of Generation C were specially developed with a focus on low noise levels and low frictional torque. They are particularly suitable, for example, for use in electrical machinery, ventilators, washing machines and power tools.

The grinding experiment was operated in the ball mill (φ460mm × 600 mm). The grinding media was forged steel balls, whose effective volume was 0.1 m 3. The loading ore and media addition were calculated through equalities (5) [ 32] and (6) [ 32 ]. (5) M = V × φ × η × χ × δ o (6) G = V × φ × δ b

The motion of an individual ball in the charge is complicated in practice and it is not possible to calculate the path taken by a particular particle during station of the charge. However the general pattern of the motion of the media can be simulated by discrete element methods which provide valuable information about the
