   Aliva® 263i Shotcreting Machine
Click here to download catalogue
Configuration
Simple but multi functional

Description
The Aliva 263i is a very sturdily constructed two-axle shotcreting machine for the processing of wet or dry mixes

Working Principle

The Working of the shotcreting machines is based on the rotor principle.The concrete mix is transported by thin stream method (compressed air stream) to the spraying nozzle.

Gasket Plate Lubrication

Automatic lubrication of sealing plates reduce wear and abrasion and thus maintenance costs.

Original Accessories

A large number of well matched accessories allow maximum machine output with high-quality results.

Theoretical Performances

Rotor Volume:   10 / 16 / 25 litres
Output:           10-15m3/h

Operation
Precise and variable

Pulsation Free
Thanks to pulsation free conveyance the thin- stream process is also suitable for manual spraying.

Liquid Dosing Unit
The dosage unit is coupled to the shotcreting machine. The selected accelerator dose is automatically adapted in function of the output of the shotcreting machine.

Concrete Mix AS Desired
Shotcreting machine Aliva 263i is suitable for spraying wet and dry mixes. Case by case you can choose the optimal process. Switching over from dry mix spraying to wet mix spraying can be done without any modification of the machine and without any additional machine components. No need for a pumpable mix with the wet spraying thin stream method. Minimum slump:8 cm

Simple Maintenance
Cleaning of the machines is extremely simple and quick. Hopper and feeder drum swing open thanks to a rotating mechanism.
