Cement Plaster Spraying Machine: Overview and Usage
The cement plaster spraying machine is a versatile and efficient tool designed for a wide range of construction applications, such as reinforcement, leveling, painting, and pumping. It is ideal for both ordinary mortar and specialized mixtures, making it a multi-purpose solution for interior and exterior wall plastering.
Applications of the Cement Plaster Spraying Machine
The machine can be used for:
-
Ordinary mortar plastering on interior and exterior walls
-
Plastering plaster and lime-based plasters
-
Thermal insulation mortar and bonding mortar
-
Tile bonding and filling mortar
-
Repairing cracks and surface finishing (face ash)
It supports both pre-mixed dry mortar and wet mortar, allowing flexibility in material use. By changing the spray gun and screw pump, you can adapt the machine to different mortars, materials, and air volume requirements.
Steps to Operate the Cement Plaster Spraying Machine
-
Preparation Before Operation
-
Inspect Electrical Components:
-
Check the motor, power supply, transmission lines, and electrical control box.
-
Ensure switches and connections are in working condition.
-
Lubricate Components:
-
Use the hand oil pump to apply lubricant to moving parts.
-
Clean the Hopper:
-
Remove any debris, slag, or leftover mortar from the hopper.
-
Check Hoses and Nozzles:
-
Inspect the shotcrete hoses, air ducts, and spray nozzles for clogs, cracks, or damage.
-
Air Transportation and Machine Test
-
Motor Rotation Test:
-
Briefly jog the motor to confirm the correct rotation direction:
-
Main motor: Clockwise
-
Air compressor: Counterclockwise
-
Air System Check:
-
Adjust air compressor pressure and air volume to meet application requirements.
-
Test the spray gun for proper air release.
-
Voltage Inspection:
-
Ensure the power supply voltage is stable at 380V.
-
Check transmission lines, wire diameters, and joint connections for safety.
-
Adjust Air Pressure and Airflow
-
During transportation, air pressure switch components may loosen.
-
Readjust the pressure spring to achieve the correct air pressure and airflow settings.
-
Spraying Operation
-
Load the prepared mortar mixture into the hopper.
-
Start the machine and ensure consistent mortar flow.
-
Hold the spray gun at a steady distance (10–15 cm) from the wall surface.
-
Move the nozzle in smooth, overlapping strokes for uniform application.
Routine Maintenance
To keep the cement plaster spraying machine in optimal condition, regular maintenance is essential.
1. Before Operation
-
Inspect electrical equipment, including motors, switches, and power lines.
-
Lubricate moving parts using the oil pump.
-
Check the hopper for mortar residue or blockages.
-
Inspect hoses, nozzles, and air ducts for damage.
-
Verify air pressure, air flow settings, and motor rotation direction.
2. After Operation
-
Clean the hopper, hoses, and nozzles immediately after use to prevent material buildup.
-
Drain excess water from the air compressor and clean filters.
-
Lubricate parts and check for wear and tear.
