The structure and working principle of the Dry Mix Shotcrete Machine: the mixed material enters the hopper of the sprayer through the vibrating screen, and is injected into the straight through material cavity of the rotor by the dialer or the wind pressure, and then transferred to the discharge port with the rotor. The compressed air entering the air chamber blows the material into the discharge elbow; another pressure air is introduced by the cyclone, and the material is blown away and accelerated in the form of a multi-headed spiral wind beam, and makes it rotate and float, and enter the conveying system. The material pipe reaches the nozzle, and then add a small amount of supplementary water (when spraying damp) or liquid accelerator (when spraying wet) at the nozzle and spray it out.
Dry Mix Shotcrete Machine is mainly composed of driving device, rotor assembly, air duct system, spraying system and electrical control box.
Dry Mix Shotcrete Machines are suitable for the harshest construction conditions and require very little maintenance, but must be maintained regularly.
The sealing plate and the rotor lining plate are the key parts of Dry Mix Shotcrete Machine, and we must pay great attention to their maintenance to ensure that there is no failure in the work.
