Clyde Process has powered pneumatic injection solutions across many industries and has consistently improved productivity rates, system reliability, availability and performance for organisations who operate within markets such as iron and steel and non-ferrous metals.

Total Pneumatic Injection Capability – Wherever there is a need to inject powdered or granular materials, into a process environment, there is a potential application for Clyde 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.

Pneumatic Injection Technologies – RotoFeed and RotoScrew

The RotoFeed and RotoScrew systems both consist of two pressure vessels, a rotating volumetric feeder at the outlet and valves to control the air supply, material flow and vessel pressure. The volumetric feeder will be driven through a gearbox by a standard induction motor.

The RotoFeed and RotoScrew systems have been widely used in the power, steel and pig-iron industries, in order to continuously inject coal into blast furnaces, reducing the requirements of coke, and allowing fines to be injected straight into the blast furnace. Injection rates usually average at 185kg/ton of hot metal, although some operations have injected up to 210kg/ton of hot metal.

The RotoFeed can feed fine powders and the RotoScrew can feed cohesive or irregular and large granular materials as well as lightly abrasive materials.
