details
Summary:
       This machine is a pneumatic wet concrete spraying machine, which adopts the design scheme of full pneumatic drive. The whole machine does not need electricity to solve the potential safety problems. It is mainly used for shotcreting in inflammable and explosive dangerous environments such as underground coal mines, metal mines, tunnels, subways, high marsh and high dust mines. It uses compressed air to transport the concrete mixture with a certain proportion through pipes and spray it onto the sprayed surface at a high speed to set and harden, Thereby forming a concrete support layer. With its advanced spraying method, the wet concrete spraying machine can spray wet materials with water cement ratio greater than 0.4, supplemented with appropriate coagulant, so that the concrete materials can be rapidly solidified without forming fluid. This type of machine is environmentally friendly and dust-free, greatly improves the construction environment, and has the advantages of low rebound rate and high solidification strength.
       The machine adopts a special design method and adopts a full pneumatic drive and a pneumatic drive forced accelerator delivery metering pump system. The accelerator delivery is stable and the metering is continuously adjustable. The atomized jet and nozzle materials are mixed to make the accelerator and concrete mix evenly and better ensure the spraying effect.
       The unique multi head spiral air conveying technology is adopted to make the spraying material flow uniform and stable, overcome the problems of pipe blocking, pulse and segregation, and make the spraying layer concrete dense, uniform and high in strength.
       This machine can be used for underground mining face operation in coal mine.

Characteristics:
1.Full pneumatic drive, without electricity, safe and reliable;
2.Wet spraying, environmental protection, no dust, low rebound rate and high material utilization rate;
3.The forced accelerator delivery metering pump system has more stable delivery, long delivery distance and more accurate metering. The mixing of atomized jet and nozzle materials makes the accelerator and concrete mix more evenly;
4.High safety and stability. Ma grade wear-resistant parts and national standard products are adopted to ensure the safety and stability of the equipment;
5.High performance, multi head spiral air conveying technology makes the shotcrete layer dense, uniform and high in strength;
6.Underground explosion-proof products of coal mines can be used for explosion-proof operations in all fields such as mining faces.
