SlamJet and CavTube spargers are designed, engineered and optimized for each coal and mineral processing application. The CPT SlamJet sparger can be removed without draining the separator or shutting down the system. This unit automatically shuts off in the event of a supply gas failure to prevent process fluid from backing up into the gas line. A single, large-bore orifice virtually eliminates plugging or fouling. The simple design and durable construction of SlamJet spargers ensure a long operating life. The CPT CavTube sparger uses hydrodynamic cavitation to produce fine bubbles that enhance separation for improved product grade and recovery. CavTube sparging systems are used for column flotation.
