A shotcrete machine is a device used to spray concrete onto a wall, tunnel or other structural surface. Its main parameters usually include the following aspects:
1. Spraying pressure: This refers to the maximum pressure that the concrete sprayer can apply, usually expressed in MPa (megapascals) or psi (pounds per square inch). Spraying pressure affects the spraying distance and effect of concrete.
2. Concrete delivery volume: This refers to the amount of concrete that the concrete sprayer can deliver per hour or minute, usually expressed in cubic meters per hour (m³/h) or cubic meters per minute (m³/min). This parameter affects construction efficiency and production capacity.
3. Spraying distance: This refers to the maximum distance that sprayed concrete can reach, usually expressed in meters (m). Spraying distance affects the flexibility and scope of application of construction.
4. Nozzle type and size: Different types of dry shotcrete machine nozzles and their sizes affect the particle size and spraying effect of sprayed concrete. Nozzle design is usually related to the viscosity of concrete and construction requirements.
5. Concrete particle size: The particle size of sprayed concrete affects the spraying quality and uniformity. Generally speaking, the maximum particle size of shotcrete should be selected according to the design of the sprayer.
6. Spraying speed: This refers to the speed at which concrete passes through the nozzle, usually expressed in meters per second (m/s). The spraying speed affects the coverage effect and adhesion of the concrete.
7. Air compressor requirements: Gunite Machines usually need to be used with air compressors, and the pressure and flow requirements of the compressor have a direct impact on the performance of the sprayer.
8. Weight and size: The weight and size of the sprayer determine its mobility and applicable scenarios, especially in small or inconvenient construction environments.
9. Motor power: This refers to the power required by the motor of the concrete sprayer, usually expressed in kilowatts (kW). Motor power affects the overall performance and efficiency of the equipment.
These parameters together determine the performance and scope of application of the concrete sprayer, and these factors need to be considered comprehensively when selecting and using the sprayer to meet specific construction needs.
