As coal mines are dug deeper, geological conditions become increasingly complex, construction conditions worsen, and the transportation costs of equipment and materials rise. Using long-distance conveyance to achieve shotcrete for tunnel support will significantly reduce labor and time costs during construction.

The PYS7IL-J type mining long-distance concrete sprayer operates on a rotor principle, featuring full hydraulic control. By enhancing lubrication of the friction plate and hydraulic clamping, it improves sealing performance and reduces waste of air volume, achieving long-distance concrete spraying. This alleviates the labor intensity for workers and, at the same time, the dust control system effectively lowers the dust concentration at the spraying site. It boasts advantages such as quick operation for on-site staff, minimal wear on moving parts, high degree of automation, and low operating costs.

Performance Features:

1. Infinite adjustment of concrete jet volume for long-distance concrete spraying operations.

2. Automatic lubrication ensures sealing performance, effectively reduces wear on moving parts, and improves the utilization rate of compressed air flow.

3. The clamping mechanism features automatic clamping for stable and controlled force.

4. The dust removal system reduces dust emissions during the operation process, protecting the health and well-being of the workers.

5. The rapid-set agent is automatically added evenly, effectively reducing rebound.

6. Automatic flip of the hopper base reduces the labor intensity of maintenance.

7. The crawler undercarriage allows for automatic movement, offering convenience and speed.

Key Technology:

Hydraulics and mechanics are combined to achieve stepless adjustment of concrete spraying volume.

2. Lubrication method of friction pair consisting of friction plates and rotating linings, as well as an automatic lubrication system.

3. Regional automatic hydraulic clamping for long-distance transport.

4. Automatic system control.
