Summary：
       PS series concrete spraying machine is wet shotcrete machine, the machines are certificated by the national Mining Products Safety Approval and Certification Center, MA security number: MEF130697, Rail wheel gauge: 600mm, 762mm, 900mm optional, operating voltage: 380 / 660V, 660 / 1140V optional. PS series of mine shotcrete machine is mainly used in coal mine, metal mine, tunnel, subway, high marsh high dust mine and other flammable and explosive dangerous environment shotcrete work, It can spray the mixing material that water-cement ratio of more than 0.4 wet material,and supplemented by a suitable coagulant, so that the concrete can quickly solidify without the formation of fluid, the kind of environmentally friendly dust-free, large Improve the construction operating environment.the kind of environmentally friendly without dust, Greatly improve the construction work environment, with low resilience, high solidification strength.
       The machine adopts the double explosion-proof motor drive, the motor drives the forced accelerator pump and metering system, makes the accelerator transportation more stable, the measurement is more accurate, the measurement is continuously and adjustable, the atomizing jet mixed with the material in nozzle makes the accelerator mix with the concrete evenly and effectively solve the problem of pneumatic quick-setting agent system pressure is low, the delivery distance is short, the measurement is instability, and this technology can be better to ensure that the spray effect.
       Using the multi-head spiral air transport technology, so that the jet material flow evenly and steadily, and overcome the problem blocking, pulse, segregation, and make sprayed concrete dense, homogeneous, high strength.

Characteristics：
1.Wet spraying,environmental protection without dust, low resilience, high material utilization;
2.Dual explosion-proof motor driven, more powerful performance;
3.Motor-driven forced metering pump system, delivery more stable, delivery distance is far, more accurate measurement, atomized jet mixing with material in the nozzle so that the accelerator and concrete mixing more uniform；
4.High safety and stability, the use of MA-level pieces of wear-resistant parts and GB products to ensure the safety and stability of equipment;
5.High-performance, multi-head spiral air transport technology so that sprayed concrete dense, homogeneous, high strength;
6.Coal mine explosion-proof products, can be used for mining underground and other areas of explosion-proof operations.
