Refractory small shotcrete machines for sale is to use compressed air to convey the pre-dampened mix through delivery hose to the nozzle to project the material onto the sprayed surface under high velocity, and then to form concrete support laer after the projected material coagulates and hardens.
With simple technology, special effect, economy cost, flexibility and high construction efficiency, shotcrete technology has widely been applying in construction, railway and super highway engineering, underground engineering, tunneling, mining operations, hydropower projects and slope stabilization, etc. As well as industrial furnaces and heat-resistant layer of spraying work.
