A refractory gunning machine is used to spray refractory materials onto a heating furnace's walls and other surfaces. It ensures that the refractory lining is thick and even and adheres well to the furnace surface, providing thermal insulation and protection against high temperatures.
 
A refractory gunning machine for a heating furnace is a valuable tool for ensuring the structural integrity and thermal insulation of the furnace. It allows for efficient and uniform application of refractory materials, reducing labor costs and project duration while maximizing the lifespan and performance of the furnace.
 
The machine typically uses compressed air to propel the refractory material through a hose and nozzle. The material is mixed with water or another binder on-site to achieve the desired consistency for application.
 
We have various models of refractory gunning machines available with different specifications such as spray capacity, conveying distance, aggregate size, and air consumption. For example, output ranges from 0.7m³/h to 9m³/h, conveying distance of up to 200m, and aggregate size of up to 20mm.
 
Key components and working principles of refractory gunning machine for repairing heating furnace:
Driving Device: Provides the power necessary for the operation of the machine.
Rotor Assembly: Contains blades that mix and propel the refractory material through the hose.
Airway System: Supplies compressed air to the rotor assembly, aiding in the mixing and spraying of the refractory material.
Injection System: Controls the flow of refractory material into the rotor assembly.
Electrical Control Box: Houses the electrical components that control the operation of the machine.
The working principle involves mixing the refractory material with water to form a slurry, which is then propelled through the hose by compressed air supplied by the airway system. The rotor assembly mixes the slurry and sprays it onto the desired surface.
