PZ-5 dry spraying machine

A dry spraying machine is a device that adds sprayed raw materials (concrete, cement, etc.) to the hopper and sprays dry concrete. It applies pressure through an air compressor to deliver the dry material to the nozzle, where there is an inlet pipe. The dry material is mixed with water at the nozzle and then sprayed out. Widely applicable for shotcrete construction operations in mines, tunnels, culverts, subways, slope support, hydropower engineering, underground engineering, and high gas mine tunnels in coal mines.
