Free energy | Endergonic vs exergonic reactions (article ...
Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called endergonic reactions. In this case, the products, or final state, have more free energy than the reactants, or initial state.
Powder metallurgy – basics appliions
Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 4010 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling: The basic principle of fluid energy mill is to induce
HEAT CONDUCTION EQUATION H
EQUATION H eat transfer has direction as well as magnitude. The rate of heat conduction in a specified direction is proportional to the temperature gradient, which is the rate of change in temperature with distance in that direction. Heat conduction in a medium, in general, is threedimensional and time dependent, and the temperature in a medium varies with position as well as time, that is ...

Size Reduction and Energy Requirement
· This equation reverts to the Bond equation (Equation ) by taking the value of B as 12 and integrating; thus, () E = k 1 P 6 12 − 1 F 6 12 which in effect is the Bond equation. Bond's original work on establishing the energy for size reduction was established in a m (8 foot) internal diameter wet grinding overflow type ball mill.
Determining Electric Motor Load and Efficiency
amperage draw of a motor varies approximately linearly with respect to load, down to about 50% of full load. (See Figure 3.) Below the 50% load point, due to reactive magnetizing current requirements, power factor degrades and the amperage curve becomes increasingly nonlinear. In the low load region, current measurements are not a useful indior of load. Figure 3 Relationships Between Power ...
