To calculate the EELS and CL, in the frequency domain, we employed the radiofrequency (RF) toolbox of COMSOL in a 3D simulation domain, where the Maxwell equations are solved in real space and in the frequency domain. We utilized an oscillating "Edge Current" as a fast electron beam along a straight line representing the electron beam.

Crusher Efficiency Calculations
A grid chart or curve for the selected crusher shows that, for a 2½-in. setting, 54% of the material will pass a 1½-in. screen, or 46% will be retained (this is like Jaw Crusher capacity table above where 48% passes a 1½ in. screen). The 46% of 70 tph gives the 32 tph fed to the secondary crusher shown in Figure below as a roll crusher.

Crushing Mechanism for Soil Particles
Typically, soil samples must be crushed into particles for laboratory research. Thus, an efficient mechanism to ensure a uniform particle size is essential. We previously developed a rod mill device that performs well, but video analysis indicated that the shear forces applied by the rod were more effective than the compressive forces applied by the mill.

A great number of solutions is obtained with the scenario-based simulation, yet we demonstrate by a conservative pattern. Namely, a reference is specified under a relatively modulate power output of both PV and WTG, and comparisons are made by considering scenarios under variations of PV and WTG power generation.

At very low BE, the electronic states suffer a depletion, leaving only a weak state close to the Fermi energy (BE ≈ 0.4 eV) and a second state at ≈1.2 eV, which disperses to different k || and gradually assumes the usual Dirac cone shape before 2 eV (Figure 3c). Such states are clearly visible on the linear scan of the plot intensity around ...

Liner wear directly impacts the gap dimension as well as the chamber profile ( Bearman and Briggs, 1998, Svensson and Steer, 1990, Westerfeld, 1985 ). Hence, liner wear is an important variable in the overall crushing operation as it is intimately related to product quality (size consistency and throughput) and cost.

Secondary Crushing Simulation
In Figure 4-B current draw is plotted against the reciprocal of the crusher set. If W ci is held constant at 0.3 times V, where V is a multiplier, a 10% increase in W ci feed rate causes the current to increase by 1.2 amp. The effect of a 10% increase in W ci is not as large (current increases by about ½ amp).
