TYPES AND COMPONENTS
Difference Between Dry Shotcrete Machine And Wet Shotcrete Machine
1. The dryness and wetness of slurry is different. The slurry added in the dry shotcrete equipment is dry, with no water or only a small amount of water. Stirring mixed material is added into the wet spraying machine.
2. Different shotcrete mode. The dry type requires water when spraying to ensure the spray effect, and doesn’t produce too much dust. The wet type uses water to fully mix the concrete or cement first, so it doesn’t need water at the nozzle. Even so, it won’t produce dust and can ensure the working environment.
3. Different conveying distance and wind pressure. The vertical and horizontal conveying distance of dry type is larger than that of wet type. Meanwhile, the wet shotcrete equipment needs more wind pressure.
4. Differences in operators and safety. The dry type needs more operators. In addition, it usuallt produce a large amount of dust which will affect environment and health of workers. However, the slurry of wet type is mixed before, which can help save labors. At the same time, it is environmental protection.
5. Different resilience and cohesion. Dry type has high rebound rate and poor cohesion. Meanwhile, the wet type with low rebound rate and high cohesion isn’t easy to deform with crustal changes, which plays an important role in safe production.
Components And Working Principle of Shotcrete Machine
The shotcrete machine is mainly composed of cement slurry mixer, extrusion type cement slurry pump, rotor type concrete spraying machine, electric control box, air circuit system, discharge elbow, mixing device, spray gun, rack, etc…
1. Cement slurry mixer is mainly composed of electric motor, gearbox, water box, up and down mixing drum, water tank control valve and feeding valve on the mixing cylinder. The device can achieve continuous work.
2. Extrusion type cement slurry pump composed of electric motor, gearbox, eccentric wheel rack, rubber hose, pipe connection is a kind of positive displacement pump, which has strong self-absorption capacity.
3. The rotor type concrete spraying machine is mainly composed of hopper, mixing device, discharge elbow, reducer, air circuit, rotor and some other parts. The motor drives rotor to rotate through the reducer, then load the mixed concrete material into the rotor and it will be sent out of the discharge elbow by the air pipe in air circuit system. Then the mixture is injected into the air duct by the auxiliary air duct system, and then ejected through the delivery pipe and nozzle.
Introduction of Shotcrete Machine
Concrete shotcrete machine, also known as the name of concrete spraying machine is an equipment that uses compressed air to continuously convey concrete along the pipeline and spray it onto the construction surface. The dry type uses pneumatic to convey dry mixing material, and then it is sprayed at the nozzle after mixing with pressurized water. The wet type uses pneumatic or concrete pump to convey concrete mixture, and then the mixing material is sprayed through a nozzle.
Uses of Shotcrete Machine
- Varieties of concrete construction projects, such as, mine, tunnel, subway, hydropower project, underground engineering, coal high-moisture mine, roadway jetting, etc…
- Spraying molding and repair of various industrial stoves and refractory for lining.
- Soil transportation and spraying in various slope protection greening construction.
