ISO9001 Cement Spraying Machine Mine Concrete Gunite Spray Machine

Description of Dry Sprayer Shotcrete Grouting Machine

The 10 material cavities in the rotor of the spraying machine are made of special rubber and shake under the action of wind to form self-cleaning to prevent the material from sticking.
Product description of shotcrete machine: widely used in engineering construction, mines, tunnels, culverts, subways, hydropower projects, underground engineering, and coal swamp mine roadway shotcrete construction operations: various types of industrial furnaces, refractory linings for spray molding or Repair: In various slope protection and greening construction, soil transportation, and spraying. The machine can be used for wet spraying, dry spraying, and individual fiber spraying.
Its working principle is that the cement slurry from the mud pump is mixed with the sand and stone and a quick-setting agent sprayed by the shotcrete machine in the mixer, and then the mixed material is sent to the spray gun by the conveying pipe for spraying operation.

Features of Dry Sprayer Shotcrete Grouting Machine

The shotcrete machine is mainly composed of the rotor-type concrete sprayer, cement slurry mixer, extrusion cement slurry pump, electrical control box, discharge elbow, air system, mixing device, spray gun, frame, and other parts.
1. Jet machine: It is mainly composed of a hopper, stirring device, discharge elbow, air system, rotor, reducer, and other parts. The motor drives the rotor to rotate through the reducer. Load the mixed material into the rotor, and send it out of the discharge elbow by the air pipeline in the air system, and then the assistant of the auxiliary air inlet pipeline in the air system sends the mixed material through the conveying pipe, Nozzle, spray to the spray surface.
2. Cement slurry mixer: It is mainly composed of the electric motor, gearbox, water tank, upper mixing barrel, lower mixing barrel, water tank control valve, and feeding valve of the upper mixing barrel. This cement slurry mixer is a double-barrel type. Stir one barrel in the upper bucket first, then put it into the lower bucket for preparation, and after the upper bucket and stir another bucket, then start the mud pump, so that it can work continuously.
3. Extrusion cement slurry pump: It is mainly composed of a motor, gearbox, pump casing, eccentric wheel frame, rubber hose, pipe joint, etc. The pump is a positive displacement pump, which does not require irrigation and drainage, and has a strong self-priming ability.
4. Mixing device: This mixing device is composed of left and right spiral stirring assembly and mud input device. Connected to the screw stirring assembly are the delivery pipe and the spray gun.

Application of Dry Sprayer Shotcrete Grouting Machine
The shotcrete machine is used in mines, tunnels, culverts, subways, hydropower projects, underground projects, and shotcrete construction operations in coal mines and swamp tunnels.
1. Underground engineering: Main support and lining of mine roadways, flexible tunnels, hydraulic tunnels, and cavities of various types of use (underground power station underground warehouse. Film, etc.).
2. Thin-walled structural engineering: thin-shell roofs, prestressed construction of reservoirs and storage tanks, etc.
3. Repair and reinforcement work: bridges, seawalls, chimneys, cooling, bridges, dams, tunnels, docks, building structural reinforcement, chemical corrosion, fire, earthquake, explosion shock, overload or construction quality, the most unfavorable factors such as repair damaged structure.
4. Breakwaters in geotechnical engineering, slopes, dams, tunnels, reservoirs, swimming pools, deep foundation pits, irrigation, and retaining walls.
5. Protection works with all kinds of fireproof coatings for steel structures.
6. Refractory items: building chimneys and various hot furnaces and repairs.
