METHOD OF MAKING PROPPANTS AND ANTI-FLOWBACK ADDITIVES USING GEAR PELLETIZERS

摘要

A method of making a proppant may include providing a feed material, extruding the feed material through a nozzle of a rotating body to form a green body, the nozzle being positioned between a plurality of projections and passing from an exterior of the rotating body to a core of the rotating body, and sintering the green body to form the proppant. The method may include drying the green body prior to the sintering. The extruding may be performed using a gear pelletizer. An feed material composition may include a ceramic precursor, a binder, a lubricant, and water. The ceramic precursor may include bauxite. The ceramic precursor may include bauxite and calcium carbonate. The binder may include sodium lignosulfonate. The lubricant may include aluminum stearate, zinc stearate, or oleic acid. The sintered proppants may have a density greater than or equal to about 3.7 g/cm3.
