Projectile Motion Formula, Equations, Derivation for class 11
Time to reach the Maximum Height by a projectile (with derivation for class 11) projectile motion: components of initial velocity V 0. When the projectile reaches the maximum height then the velocity component along Y-axis i.e. V y becomes 0. Say the time required to reach this maximum height is t max. The initial velocity for the motion along …

Mill Critical Speed Formula Derivation
d = diameter of the ball. In practice Ball Mills are driven at a speed of 50-90% of the critical speed, the factor being influenced by economic consideration. Mill capacity can be increased by increasing speed but there is very little increase in efficiency (i.e kWht-1) when the mill is operated above about 40-50% of the critical speed
Ball Mill Design/Power Calculation
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and …
ATTRITORS AND BALL MILLS HOW THEY WORK
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

5 An introduction to Yang-Mills theory
derstanding of the Yang-Mills equations. Far from it — such an understanding cannot possibly be obtained by reading a short set of notes on the subject. This should not be surprising, since the Yang-Mills equations generalize Maxwell's equations, and under-standing Maxwell's equations even passingly well requires years of work. To develop a

Classical Yang-Mills theory
we fill this gap by discussing classical Yang-Mills theory coupled to point sources. We derive the equations of motion for the coupled particle-field system and present several example solutions to these equations for Yang-Mills theory in (1þ1) dimensions. In Sec. II, we briefly review ordinary classical electrody-namics.
