Embodiments of an hydraulic opposed jet mill are disclosed which may be used to crush various minerals, including mica, or other materials to sub-micron size. At least one positive displacement pump forces an incompressible liquid, such as water, through a pair of opposed jets such that the two streams of water collide between the jets. A slurry of an incompressible liquid, such as water, and the mineral to be crushed is introduced into the jets at a point near the outlet end of the jets. The entrained mineral particles are forced out of the jets with great energy which causes multiple collisions and pulverization. In a second embodiment of the instant invention the slurry strikes an impingement plate rather than an opposed slurry stream.

There is provided a showerhead device that includes a shower stem connector, a water/air mixing chamber, and an outlet cap. The shower stem connector includes a water inlet to receive water from a standard shower plumbing system and an air intake opening to receive air from outside the device. The preferred embodiment features an air intake opening located near the water inlet on the shower stem connector. A user can adjust the air intake knob in order to vary the amount of air that enters the device and mixes with the water flow. As the water progresses through a nozzle in the device, the speed of the water is increased by the decrease in diameter of the nozzle orifice. The water mixes with the air and the combination of water/air hits a plate on the inner wall of the outlet cap within the mixing chamber. This oxygenation of the water provides for a better water flow though the showerhead device. The mix of water and air provides for a stronger water flow and a better shower experience for a user. By having the air intake further upstream, it enables a user to adjust the amount of air mixed in.
