pneumatic, for powders and granulates


Schenck Process has designed pneumatic injection solutions across many industries and has consistently improved productivity rates, system reliability, availability and performance for organizations that produce power by burning solid fuels. Wherever there is a need to inject powdered or granular materials, into a process environment, there is a potential application for Schenck Process injection technology. Products can be continuously injected into process environments at smooth, easily controlled rates, with accuracies ±0.5% and against back pressures of 20 barg or more. The RotoFeed machine consists of two pressure vessels, a rotating volumetric feeder at the outlet and valves to control the air supply, material flow and vessel pressure. The dispensing vessel is used to provide a constant supply of material to the volumetric feeder. When the material is being injected, the dispensing vessel will be pressurised. The lock vessel is used to periodically replenish the dispensing vessel with material. In this way, injection of material to the process can be continually maintained. The RotoFeed system has been used in Power industries, in order to continuously inject wood pellets and saw dust into the pulverizer allowing for a safer more efficient method of handling this volatile fuel.
