Abstract

A system for charging flowable solids and mixing with water, including a solids charging hopper, a feed auger and a cyclonic mixer. The hopper has an open top with detents around the rim of the top which are capable of engaging and holding the rim of a container. The auger passes through the bottom section of the hopper, and the hopper can rotate about the axis of the auger, permitting inversion of a container attached to the detents. The auger feeds material from the hopper to the cyclonic mixer. The cyclonic mixer has a mixing chamber with a top surface having radial undulations or striae and a bottom discharge port with longitudinal undulations or striae for controlling vortex formation. Water is injected into the mixing chamber through a tangential inlet port.
