The rotor gunning machine function

A rotor gunning machine functions bycontinuously conveying dry or pre-moistened material from a hopper into a rotor chamber, which then uses compressed air to spray the material through a hose to a wall or surface. The material is mixed with water at the nozzle to create a paste, and the machine can be used for applications like concrete spraying and refractory lining repairs.

• Loading: Dry or slightly wet material is fed into a hopper.

• Conveying: The material falls into a rotor chamber and is moved to an emptying position as the rotor turns.

• Transport: Compressed air at the discharge point blows the material into a hose or pipe.

• Moistening and spraying: Water is added at the nozzle, moistening the material just before it is sprayed onto a surface, forming a new layer.

• Material processing: It can handle both dry mixes and pre-moistened materials.

• Application: It is used in both the construction and refractory industries for spraying concrete and applying refractory materials to surfaces like industrial furnaces.

• Efficiency: The rotor system provides continuous, high-performance spraying, which can reduce waste through lower rebound rates.

• Low dust: Modern versions are designed for low-dust and low-wear operation, especially important for high-cost refractory materials.

• Adjustable output: The speed of the rotor or other controls can adjust the material flow rate to suit different applications.
