PZ-5I explosion-proof dry spraying machine

The explosion-proof dry spraying machine has the characteristics of technology, reasonable structure, stable performance, convenient operation and maintenance, and long service life. It is widely used for shotcrete construction operations in tunnels, culverts, subways, hydropower projects, underground engineering, and high methane mine tunnels in coal mines. The basic process is to use force to pass the pre mixed concrete through the pipeline, connect compressed air and accelerator at the nozzle, and then spray the concrete at high speed onto the sprayed surface. After rapid solidification and hardening, the concrete support layer is formed. With the large-scale development of modern engineering construction, the market demand for shotcrete trucks has rapidly increased in recent years, and the requirements for construction efficiency have also become increasingly high. The construction efficiency is not only reflected in the spraying process, but also in the flexibility of the product.
