Shotcrete Machine Introduction
We have engineering oriented shotcrete machine and mine oriented shotcrete machine, wet or dry shotcrete machine.
Shotcrete Machine Difference
Wet shotcrete machine can spray dry material or wet material.
Dry shotcrete machine can only spray dry material.
Wet shotcrete machine has a set of pumping system (accelerator conveying system) more than
dry shotcrete machine, with a small motor of 0.75 kw.
It is suitable for tunnel, high-speed railway and highway.
Mine shotcrete machine uses concrete pump to convey concrete through pipeline to the nozzle of manipulator, and uses compressed air with accelerator to spray concrete to the wall of shotcrete roadway.
It is widely used in various working environments, such as tunnels, culverts, subway, hydropower projects, underground projects, slope protection and high methane mine roadways.

Shotcrete machine Feature
1. Through the rotor type non-bonded material chamber, the discharge is smooth,efficient and time-saving.
2. Four-point elastic compensation compaction, good sealing effect, less dust near the machine, long service life of vulnerable parts.
3. Using low pressure and high speed swirling airflow to convey materials to overcome the sticking and blockage of pipes and pulses in conveying materials.The material flow is uniform, continuous and stable.
4. New sprinkler and elbow device can improve spraying effect with less springback and high spraying layer quality.
5. The chassis of the machine can be assembled into tyre type, skid type and wheel type with various gauges.
Shotcrete machine Application
Shotcrete machine is widely used in building wall spraying slope, slope protection, tunnel construction and other places without harmful gas and need concrete spraying.
It is also called concrete spraying machine mainly used for slope protection anchorage, foundation pit reinforcement, tunnel spraying anchorage,concrete spraying in tunnels, culvert, underground construction, slope protection projects and mine roadway construction.
