Abstract: Blending particulate and liquid to make slurry for use in oilfield operations is addressed. The blender has an upwardly facing particulate expeller with a flat base, raised hub, and generally radially extending, circumferentially spaced vanes extending upwardly from the base. The vanes extend from leading edges spaced about a vane inner diameter to tips spaced about a vane outer diameter. Adjacent expeller vanes define expeller passageways therebetween.
