Claim 18:
19. A system for creating a proppant slurry for use in hydraulic fracturing operations, the system comprising:
a wet screening assembly comprising a screen with a plurality of openings through which proppant and fluid may pass, and a hopper with an outlet disposed above at least a portion of the screen;
a proppant supply assembly comprising a variable speed motor, and wherein the proppant supply assembly is arranged to supply material comprising proppant to the hopper;
a fluid supply assembly comprising a pump and a fluid meter, and wherein the fluid supply assembly is arranged to supply fluid comprising water to the wet screening assembly;
a bin located below the wet screening assembly such that proppant and fluid that pass through the screen are collected in the bin as the proppant slurry;
an outlet in the bin for passing the proppant slurry from the bin;
wherein a concentration of proppant in the slurry is determined by a rate or rates at which the proppant supply assembly supplies proppant to the hopper and/or by a rate or rates at which fluid is supplied to the wet screening assembly; and
a conduit coupled to the bin for passing the proppant slurry from the bin without separating the proppant from the fluid.
