Mortar spraying machines can be divided into screw type cement plaster spray machines and plunger-type mortar spraying machines according to the type of work. A concrete spraying machine is a professional spraying machine specially used for spraying mortar. It can be used for spraying mortar with mortar particles below 4-5mm. The cement spraying machine is mainly used in the construction industry for exterior wall plastering mortar spraying, exterior wall insulation material mortar spraying, mortar roughening, refractory spraying, large area fireproofing material spraying, waterproofing agent spraying, and other projects.

Application of Mortar Spraying Machine:
Mortar spraying machine is suitable for indoor and outdoor wall spraying, cement mortar grouting, bridge grouting, and waterproof surface spraying, fireproof spraying, ceiling spraying, wall spraying, paint spraying. Garden spraying, relief paint spraying, sound-absorbing material spraying, waterproof plugging, waterproof and leak-proof. It is light and convenient for the construction of bridges, dams, hillsides, basements, tunnels, and housing factories. The concrete spraying machine can be used not only for spraying but also for pouring mortar.
Features of Cement Mortar Spraying Machine:
- The cement sprayer machine has fast spraying speed, high work efficiency, low labor intensity, small size, and a walking wheel is installed under the body, which is convenient for on-site movement and has a low cost of accessories and simple maintenance. The connection between the spray gun and the feeding pipe can be rotated for easy operation.
- The operation and maintenance are simple, and they can be operated skillfully without special training. No scaffolding is required, no moving equipment is required. Both the male and female corners and the roof can be sprayed freely, which shortens the construction period, improve the progress, and saves the cost of the frame material.
- It can be applied not only to the construction of internal walls but also to the construction of external walls, with a small investment, quick return on costs, and large returns.
- The project quality is guaranteed. The spraying machine introduced by our company has a large flow and high pressure (up to 3mpa), and the adhesion and density of the sprayed materials on the wall far exceed the national standards.
- One machine with multiple functions can spray mortar, fireproof paint, fireproof paint, putty paint, ordinary paint, and is not affected by regional and environmental conditions and the shape of the spray surface.
Classification of Cement Spraying Machine:
YG wall mortar plaster is mainly divided into screw mortar spraying machines, automatic mixing mortar spraying machines, and plunger mortar spraying machines.
Screw Mortar Spraying Machine
A screw mortar spraying machine is a kind of machine that disperses the mortar into a mist-like and sprays it onto the surface of the wall. The sprayed material is conveyed to the front end by a spiral, and evenly sprayed onto the surface of the object by high-pressure gas.
The structure and working principle of the new mixing and spraying machine: the stirred material is discharged from the distribution mixer, supplied to the spraying machine hopper through the vibrating screen, sent to the high pressure chamber by screw, and then rotated by the high pressure rotor and stator. At high pressure, the mortar is sent to the nozzle through the conveying pipe, and high pressure nozzle sprays the material on the wall. The cement sprayer machine is easy to use, can greatly reduce the cost, time, and operation, can be used for indoor and outdoor wall spraying.
Plunger Mortar Sprayer Machine
The plunger mortar sprayer machine directly pressurizes the paint materials by a high-pressure plug pump, which can create high pressure. After passing through the nozzle, the high pressure will encounter an obstruction, materials will be divided into many small points so that these are evenly sprayed on the surface of the object. This spraying mortar is relatively uniform, has no graininess, relatively dry. It adopts screw conveying and can output uniform flow materials, which overcomes the defects of uneven flow of existing piston pump or plunger pump. The transmission is simple and compact in structure, the replacement is quick and convenient, the maintenance is easy and the cost is low. Save a lot of time and increase work efficiency.
Matters Needing Attention When Concrete Spraying Machine:
Mortar spraying equipment can be used for mixing and spraying concrete. When mixing concrete, pay attention to the mixing time and the order of feeding. Attention should be paid to spraying operations: Spraying distance, spray gun operating speed, the overlap of spray patterns, and paint viscosity.
- When working with a large spray gun, the spraying distance should be 20~30 cm. When working with a small spray gun, the spraying distance should be 15~25 cm. If the distance is too close, the spray will be thick, and too far will be thin.
- The running speed of the spray gun should be kept at a constant speed, generally, the speed is 30/60 cm/sec. Too slow is easy to cause sagging, too fast is easy to leak.
- It is necessary to accumulate experience in daily work for the overlap of spray patterns to maximize the spraying effect.
- The temperature of the sprayed coating should be controlled at 20-30°C, otherwise, it will affect the viscosity of the coating and thus affect the spraying effect.
