Working Principle of the GRC Spray Machine System
The GRC spray machine operates through a continuous screw feeding and pneumatic spraying system that ensures stable mixing and uniform fiber distribution during production. The process begins when raw materials such as cement, sand, water, and glass fibers are loaded into the hopper. The screw system then transports the mixture forward at a controlled speed, ensuring consistent density and flow rate.
Inside the conveying chamber, the material is fully mixed and compressed under stable pressure. The adjustable motor (20–200 r/min) allows operators to control output according to different project requirements. Once the mixture reaches the spray gun, compressed air at 0.6–0.8 MPa propels the material through the nozzle, forming a uniform layer on the target surface.
Key working steps include:
- Material feeding into the 60L hopper system
- Screw conveying with constant-speed mixing
- Fiber and cement homogenization inside the chamber
- Pressure-controlled spraying through a nozzle
- Layer-by-layer deposition for structural strength
This system ensures consistent spraying thickness, reduces material rebound loss, and improves overall bonding strength. It also supports continuous operation, making it suitable for large-scale architectural and industrial production environments.
GRC Spraying Machine Technology for Precise Fiber Distribution
The GRC spraying machine integrates a screw feeding system and adjustable motor control, allowing operators to maintain stable flow and consistent mixing quality. This equipment ensures that cement, sand, and glass fibers are evenly distributed during the spraying process.
Key benefits include:
- Stable spraying pressure for uniform coating
- Adjustable speed control (20–200 r/min) for different material types
- Continuous feeding system reducing downtime
- Improved fiber bonding strength for structural durability
- Reduced material waste during operation
YG Machinery designs the system with a compact structure, making it suitable for both factory production lines and on-site construction environments.
