A mortar spraying machine, also known as a cement spraying plastering machine (or simply “spraying machine”), is a construction piece of equipment specifically designed to evenly spray mixed mortar (such as cement mortar and lime mortar) onto walls, floors, or structural surfaces using mechanical pressure. Its core function is to replace traditional manual plastering, achieving efficient and uniform mortar coverage through “mechanized spraying,” transforming wall/floor treatment from a laborious and uneven manual task into an easy “switch-on-and-go” process. As experts with many years of experience in the machinery field, YG not only provides powerful spraying technology but also offers plastering machines for complementary use. Of course, construction engineering machinery is our specialty, and we have been deeply involved in this industry for over 20 years. Whether you need professional equipment for fine interior decoration or heavy-duty machinery for large-scale tunnel support, YG can provide you with a one-stop procurement solution.

The YG Series Mortar Spraying Machine Comprises the Following Components
- Power System: Depending on the operating conditions, a stable and reliable electric motor or a powerful diesel engine is available.
- Screw Pump System: The rotor and stator, made of wear-resistant materials, are the heart of the system, ensuring stable slurry output.
- Agitator and Hopper Unit: A large-capacity hopper with an anti-clogging grille ensures the mortar is uniform in state before entering the pump body.
- Spray Gun and Air System: Precision-designed nozzles allow for control of spray thickness and uniformity through air pressure adjustment.
Check the Mortar Spraying Machine Working Principle
The core working logic of the mortar spraying machine is to achieve automated wall plastering through the coordinated operation of four major stages: feeding, mixing, pressurized conveying, and precise spraying. First, the operator pours the mortar raw materials (cement, sand, additives, etc.) into the hopper and sets parameters such as spraying thickness and speed through the intelligent control system. After starting the equipment, the double-helix feeding device of the feeding system uniformly feeds the raw materials into the mixing system. Under the action of the horizontal twin-shaft mixer, the raw materials and water are thoroughly mixed into a uniform mortar. Then, the uniformly mixed mortar enters the pressurized conveying system, where a high-pressure plunger pump pressurizes the mortar to 8-16 MPa and conveys it to the spray nozzle through a high-pressure conveying pipe. Finally, under high pressure, the mortar is sprayed out of the nozzle at high speed, evenly covering the wall surface. The operator can adjust the nozzle angle and movement speed, in conjunction with the leveling components of the automatic wall plastering machine, to achieve a smooth wall plastering surface. The entire process is fully automated, requiring only 1-2 operators to be responsible for raw material replenishment and equipment monitoring.

FAQ About Mortar Spraying Machines
Yes. Multiple models are available. The entry-level electric motor model is affordable, easy to operate, and automates operations, reducing labor costs. The equipment is mobile and adaptable to different construction scenarios. It supports future upgrades, offering high cost-effectiveness and meeting the needs of small and medium-sized enterprises.
For indoor or easily accessible power supply scenarios, choose an electric mortar spraying machine—energy-saving, quiet, and with low operating costs. For outdoor projects without a power supply or large-scale projects, choose a diesel-powered mortar spraying machine—powerful, long-lasting, and suitable for complex environments.
It can spray various materials such as cement mortar, thermal insulation mortar, and waterproof mortar. With a dedicated upgrade, it can be used as a stucco spraying machine, compatible with stucco application, providing uniform spraying, stable quality, and meeting plastering and finishing needs.
No, it’s not complicated. Daily maintenance includes cleaning the hopper for residue and checking the high-pressure hose seal; weekly checks of lubrication levels and tightening of connecting bolts; and monthly checks of plunger pump wear. The core components have a standardized design, making replacement easy, and even beginners can operate it easily.
