Liquid jet ejectors for solids use a high-velocity liquid jet to create a vacuum zone capable of aspirating and transporting granular solids, fine powders, sludges and slurries with suspended solids.
They mainly consist of a nozzle, a mixing head or chamber and a diffuser.
The motive fluid, usually water, passing through a nozzle, creates a low pressure zone where the solids introduced from the suction connection are sucked in.
Solids are usually loaded through a hopper.
A vibration system or water jets are used to facilitate the sliding of the powders along the walls of the hopper or funnel.
