Suction system CavTube

The CavTube® design is based on hydrodynamic cavitation. This occurs when the pressure in a moving liquid is momentarily reduced below its vapor pressure, creating ultra-fine air or vapor-filled bubbles. These fine bubbles are carried by the flow to a region of higher pressure resulting in a bubble dispersion that resembles fine smoke. Cavitation and the shearing of additional gas ensure the generation of fine bubbles suitable for the recovery of both ultra-fine and coarser particles. CavTubes are offered in a variety of materials-of-construction to provide a long wear life. Material selection is based on application specifics and includes polyurethane, ceramic, tungsten carbide and hardened steel. Cavitation Tube Spargers Generate picobubbles to substantially improve flotation kinetics and increase the recovery of ultrafines. Cavitation Tube spargers are the heart of the patented bubble generation technique used in Eriez Flotation column flotation cells. The specially designed CavTubes® are an integral part of the hydrodynamic aeration system used to maximize fine bubble generation and improve bubble-particle collision rates. CavTubes can also be used as part of a pre-aeration system that can be applied independently in a flotation feed line or part of a separate equipment package to increase the recovery of overloaded circuits or improve the flotation response of “hard-to-float” material.
