Usage   chinacoal10

 Building gunite machine is widely used in construction engineering and construction, mining, tunnel, culvert, subway, hydropower engineering, underground engineering and high marsh coal mine tunnel shotcrete construction operations, various types of industrial furnaces, molding or spraying refractory lining repair and  various green slope, soil transport and injection.

Feature&advantage

1. Through type rotary, non-sticky, unobstructed discharge, high efficiency and time-saving.

2. Four-point clamping device makes it easy to adjust the press between sealing plate and rotor disk so as to reduce air and dust leak and prolong consumption parts life., 

3. Using low-tension, high-speed vortex pneumatic transportation, so the spraying flow is even, continuous and steady. It's good to improve the shotcrete quality.

4. The new nozzle, discharge elbow device, improving spray deposition effect, less resilient, high quality shotcrete.
