Product Description

Product Overview:

PZ-7 shotcrete machine is widely used in engineering and construction, mines, tunnels, culverts, 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; all kinds of green slope, soil transport and injection.

Product Features:

1.No binder through rotor chamber, the material smooth, efficient and time-saving,

2.Four elastic compensation compression, good sealing effect, a small machine next to the dust, long consumable life,

3.Using low-speed vortex air transportation, to overcome the bonding material handling, plugging off and pulse away from issues such as material flow uniform, continuous and stable,

4.The new nozzle, discharge elbow device, improving spray deposition effects, less rebound, sprayed layer of high quality.

5.Advanced technology, reasonable structure, stable performance, easy operation and maintenance, long service life, the wheel-rail gauge can be swapped.
