Dry Mix Gunite Machine

Concrete Pumps: Low Pulsation Ensures Constant Concrete Flow

Concrete pumps deliver the concrete mixture to the nozzles of the spray arms. Wet mix shotcrete gunite machine is usually pumped with twin piston pumps.

The pump is designed to minimize pulsation, thereby reducing discontinuities in the flow of concrete to ensure uniform application of shotcrete machine. In this way, the desired quality and layer thickness can be achieved with less springback (concrete not left on the wall).

Spray Arms: Long Range Applications

The spray arm of the shotcrete machine positions the stream of concrete where it is needed. Spray distances up to 17 m without scaffolding or telescoping lifts.

Concrete, accelerator and air are mixed in the sprinkler head and sprayed through nozzles. The design and size of the nozzle is critical to properly compress the concrete and minimize springback.

What Are The Main Components Of Shotcrete Machine

Air Compressors: Injection And Compaction Of Concrete Mixtures

The air compressor is responsible for providing the kinetic energy required for ejection and compaction of the concrete mixture. For this, the shotcrete machine must hit the surface at a certain velocity, which can be achieved not only with the airflow provided by the compressor, but also in combination with a suitable nozzle diameter. For example, an airflow of 12 m3/min and a nozzle diameter of 65 mm do not provide sufficient kinetic energy. However, the same flow rate can be achieved with a 35-40 mm nozzle if the correct spray distance (1-2m) is maintained.

Control System: The Brain Of The Device

Monitor the correct relationship between the amount of accelerator and the pumped concrete;

Manage the proper operation and safety of concrete pumps;

Collect spray data for download and processing.

Remote Control: Security Management Of Devices

By using the remote control, the operator can manage and modify the main components of shotcrete machine (concrete and additives) as well as the components of the equipment (spray arms and nozzles). There are wireless or wired remote controls, allowing the operator to work in a safe area at all times.

Mobile Chassis: Reach The Digging Face Across Any Terrain

The equipment assembly is mounted on a motorized chassis to drive it to the spray area. In confined spaces, properties such as size, orientation and turning radius are important. Its maneuverability, angle of attack and climb capability are critical for reaching areas with slopes and irregular terrain.
