Shotcrete pumping type refractory spraying machine
Shotcrete pumping type refractory spraying machine is specifically engineered for refractory castable applications. Compared to conventional dry-mix spraying machines, it offers significant advantages, including reduced rebound rates, minimized dust generation, lower water addition requirements, enhanced density and strength of refractory materials, and substantial reduction in material waste.

As a supplier of refractory spraying machine, every model of our shotcrete pumping type refractory spraying machine is equipped with an ABB Variable Frequency Drive (VFD), a high-pressure water pump, and an innovative pre-wetting nozzle.

The ABB VFD enables precise control of motor speed to regulate output, preventing hose blockages caused by excessive material flow during startup. The high-pressure water pump supplies water to the spraying unit, where it is atomized through a water ring orifice, ensuring thorough mixing with the refractory castable for optimal pre-wetting. The advanced pre-wetting nozzle features dual needle valves that independently control two water circuits. This design allows operators to fine-tune water flow with ease, significantly reducing the need for specialized operator training.
