5m3 mine shotcrete machine shotcrete machine shotcrete head tube small concrete spraying machine shotcrete machine concrete spraying machine is mainly used in engineering construction, mining, tunnels, culverts, subway, hydropower engineering, underground engineering and high marsh coal mine tunnel shotcrete construction operations: Factory direct, welcome to order! Various types of industrial furnaces, refractory lining spray forming or repair: a variety of green slope, soil transport and injection! ! Concrete spraying machine is divided into mining and non-mining, and dry and wet. Technical parameters 5m3 concrete spraying machine: production capacity 5m3 / h maximum working pressure 0.4-0.6Mpa 150m transmission distance of 200m vertical air consumption 7-8m3 / min applicable material ratio of cement / sand = 1: 3-5 Motor Model Y132M-6-5.5KW suitable material water-cement ratio ≤0.4 voltage 380V maximum aggregate size φ21mm Dimensions 1520 × 820 × 1280mm Conveying pipe diameter φ51mm machine weighs 600kg rotor diameter φ438mm?? 5m3 concrete spraying machine is mainly Features and advantages: dry binder through rotor chamber, the material smooth, efficient and time-saving: four elastic compensation compression, good sealing effect, a small machine next to the dust, long life wearing parts: Mine explosion shotcrete machine using low-speed vortex air transportation, to overcome the bonding material handling, plugging the tube and pulse segregation and other issues, material flow uniform, continuous and stable: the new nozzle, discharge elbow device, improving spray-effects, less rebound, sprayed layer high quality.
