The 3m3/h concrete spraying gunning machine for refractory dry-mix shotcrete is specifically engineered to cater to the demands of refractory castable materials. In contrast to conventional dry-mix spraying machines, it stands out with several remarkable features: reduced rebound, minimized dust emissions, decreased water addition requirements, enhanced density and strength of refractory materials, and significant reduction in material wastage.

The ABB frequency converter enables precise adjustment of motor speed to regulate output, preventing hose blockages during startup due to excessive material flow. The high-pressure water pump supplies water to the gunning machine, which, upon atomization through water ring orifices, ensures thorough mixing of water with refractory castables, facilitating pre-wetting. The novel pre-wetting nozzle features dual needle valves, each governing a separate water circuit. Operators can fine-tune water flow by adjusting these valves, substantially reducing the skill level required for effective operation.
