PZ-9 gunite machine

Product Introduction

PZ-9-type gunite machine is used to dry spray, tidal shotcrete equipment, it has the feature of advanced technology, reasonable structure, stable performance, easy operation and maintenance, construction shotcrete machine long life, can be configured separately tire and wheel tracks two kinds of walking device characteristics. PZ-9 gunite machine is widely used in tunnels, culverts, subway, hydropower engineering, underground engineering shotcrete construction operations.

Shotcrete is the use of compressed air, a certain proportion of the concrete mixing plant will feed through pipelines and high-speed jet setting and hardening the surface to be sprayed to form concrete support layer. In recent years, shotcrete technology with a simple process, a unique effect, the economic cost and fast construction speed, construction, rail and road tunnel construction, mine development, slope reinforcement and other fields be widely used.

Technical feature

Through rotor chamber no binder , the material smooth, efficient and time-saving;

Four point elastic compensation compression, good sealing effect, little dust next machine,wearing parts with long life ;

Using low pressure high speed vortex air transport, overcome the bonding of material handling, plugging away from the pack and pulse problems, material flow uniform, continuous and stable.

New nozzle, discharge elbow device, to improve spray deposition, less resilient, high quality shotcrete.

Machine chassis can be assembled into the tire, skid-and variety of gauge rail wheel .

Working principle

Material from the ingredients stirred mixer discharge port (or manual mixing and loading) discharged into the vibrating hopper is fed through the mesh shotcrete machine hopper, feeder struck from the allocation of material injected through the rotor chamber, with the rotor to rotate at the discharge port, the gas chamber is here Walter blowing compressed air into the cyclone to the material. Here, by the introduction of another unit cyclone winds, was long the wind blew away the helical state of the material, acceleration, and make it rotate, floating into the conveying pipe to reach the nozzle and then add a small amount of added water ejected.

PZ-9-type gunite machine is mainly consisted in the driving device, the rotor assembly, gas system, injection system and electrical control box and other components.
