7.5 Kw Dry Shotcrete Machine with 7m3/h Working Capacity and 5.5-7.5 Kw Power for Efficient Concrete Spraying

Large Capacity Shotcrete Spraying Machine Dry Shotcrete Parts 7.5 Kw Remote Conveying Gunite Machine

Introduction:

1. Mechanical built-in transfer plate, adjust the size of the material mouth under the hopper, steplessly adjust the amount of concrete spraying, and realize the concrete spraying operation of long-distance transportation;

2. The hopper seat is automatically flipped, and the rotor body is automatically lifted when disassembled, and the accessories are quickly replaced to reduce the labor intensity of maintenance operations;

• Automatic lubrication of the joint surface of the joint plate and the steel liner plate to ensure sealing performance, effectively reduce the wear of moving parts, prevent pressure air leakage, and improve the utilization rate of pressure air;

4. Hydraulic pressing system to ensure accurate control of pressing force;

5. Automatic addition system of quick-setting agent, which can accurately control the amount of quick-setting agent;

6. The structure of the whole machine is more compact, which is convenient for transfer operations.

Foundation pit support concrete shotcrete machines are used for shotcrete construction in construction projects, mines, tunnels, culverts, subways, hydropower projects, underground projects, and coal mine tunnels. Concrete shotcrete machines are also used for spraying and forming refractory materials or repairing furnace linings in various industrial furnaces and kilns, and for soil transportation and spraying in various slope protection and landscaping projects.

The construction trowel sprayer, a tidal-type shotcrete machine, is suitable for railway (highway) tunnels, high-rise buildings, and water diversion culvert projects. Its simple structure makes it easy to operate and maintain. Its unique clamping device ensures a rational structure and user-friendly design, reliable performance, easy operation and maintenance, and a long service life.
