GZ-3 dry shotcrete machine is available in following versions:
Basic: electric drive can be combined with tyre chassis
Extended (optional): air motor or diesel drive combined skid or rail-wheel dry mix shotcrete machine.
According to different spraying process, shotcrete machine is divided into wet mix shotcrete machine and dry mix shotcrete machine. 
Wet mix shotcrete machine process:

Dry mix shotcrete machine principle:
1. The mixing material of ingredients mixer discharge mouth (or artificial mixing and feeding) after vibrating screen mesh for the jet in the hopper.
2. Feed by dial direct dial into rotor cavity, with the rotor vortex to the discharge port. 
3. Here from the gas chamber into the air, blow the material into the discharge elbow, introduced by cyclone another wind pressure, the state of long spiral wind blows away the supplies, acceleration, and make it spin, plankton, into the feeding tube. 
4. To shower and then add a small amount of water spray (tide) or liquid accelerator (wet) injection.

Dry mix shotcrete machine composition:
1. The driving gear (main motor, reducer, etc.).
2. The rotor assembly (turn daughter, cavity, the rotor plate, etc.).
3. The wind road system.
4. Injection system.
5. Electrical control system.
6. Walking system.
■ Application
GZ-3 Dry mix shotcrete machine can be used as well for small jobs, such as joint filling, swimming pool, refractory application and extensive slope consolidation work, etc. 

Shotcrete machine application:

1. Tunnel linings. 
2. Mining operations. 
3. Hydropower projects. 
4. Hill side projects. 
5. Swimming Pool. 
6. Concrete repair. 
7. Soil retention and retaining walls. 
8. Underground excavation engineering etc.

■ Features
Dry mix shotcrete machine features:
1. Non-adhesion going-through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period.
2. Thin flow conveying method with vortex flow, so the spraying flow is even, continuous and steady, to improve the shotcrete quality.
3. Four-point clamping device make it easy to adjust the press between sealing plate and rotor disk so as to no air and dusk leak and prolong consumption parts life.
4. Partifularly used for dry, damp mix and steel(polymer)fiber reinforced shotcrete.
5. Dry shotcrete machine chassis can be assembled into tyred, slide rail wheel type and all kinds of gauge.
