Recently one customized variable output dry spray refractory guntie machine was sent to customer. This refractory gunning machine is designed base on our normal shotcrete machine. In this machine, an ABB frequency converter is added for speed controlling. Collect dust bag is added for material saving. Pre-dampening nozzle are added for adding some water at nozzle thus lower rebound, lower dust, reduce additive water amount and improve refractory compactness and strength. This customized variable output dry spray refractory gunning machine used by many customers and get good feedback.
