The working principle of the SPZ series concrete shotcrete machine:
The SPZ series concrete shotcrete machine is mainly composed by the driving device, rotorassembly , Airway system,injection system,electrical control box. Mixed materials are discharged from the mixer into the shotcrete vibrating screen mesh feeding hopper,Injected into the rotor body through the feeder then to the outlet,compressed air is introduced from the air chamber to blow the material into the discharge elbow,at same time another compressed air is introduced by the cyclone,the material is blown away in a multi-headed wind spiral state accelerate, and output rotation, float,to the material pipe,Then,add some water or liquid accelerator and spray it out.
Features of dry shotcrete machine:
1.Through-rotor,Smooth discharge,efficiency.2.Four-point elastic Compensation Compression,good sealing effect,less dust,Wearing parts reinforce.3.Low-pressure high-speed vortex air transport,overcome sticking in material conveying,plugging and pulse distraction.The material flow is uniform, continuous and stable.4.New nozzle,outlet elbow device,improve spray effect,less rebound,high quality spray layer.5.The shotcrete chassis can be assembled into a tire type,skid type and rail wheel type of various gauges.
