Abstract
Methods and apparatus for forming proppant particles which include providing an aqueous slurry of ceramic forming raw materials, flowing the slurry through a perforated membrane, which may be energized, to form slurry bodies, receiving the slurry bodies in a collecting hopper, and drying the slurry bodies to form particles. In some aspects, the slurry is energized as it flows through the perforated membrane.
