The working principle and the structural characteristics of the dry-type sprayer are as follows: the rotor with lining board rotates in certain rotation speed, the surface combining board is pressed onto the lining board and fixed, and the combining board is connected to air inlet pipe and material outlet elbow. In the process, the sealing pair consisting of the combination plate and the lining plate plays a role in sealing air compression and materials. The main advantages of the dry concrete sprayer are long conveying distance, simple equipment and durability. However, because the dry mixing and concrete nozzle is externally mixed with water, construction dust and rebound rate are high, dust generated in dry spraying operation harms the health of workers, and dust pollution is serious especially in narrow and small roadway engineering construction.
