GZ-3ER/SC Dry mix gunning machine for refractory work is specifically designed for refractory dry-mix shotcrete applications, based on the rotor principle.

The refractory gunning equipment supports a horizontal conveying distance of 200 meters and a rated output of 0-3m3/h, which can meet the needs of operations of different scales. Its well-proven design makes it extremely robust, easy to set up, simple to operate, most economical, and a safe gunning machine. Various configurations make it the machine of choice for small-to-medium applications.

Dry gunning machines use compressed air to transport dry refractory powder (such as aluminum silicate and magnesium) from a tank to the front of the gun, where it is mixed with high-pressure water mist and then sprayed. This design avoids the sudden drop in masonry temperature caused by excessive moisture in the slurry during wet gunning, while also reducing the dust pollution associated with dry gunning. With this GZ-3ER/SC dry mix gunning machine, you can get low dust and high performance spraying flow in the nozzle.

GZ-3ER/SC Dry mix gunning machine adopts the principle of forced feeding pneumatic conveying, which uses compressed air to evenly convey the gunning material to the spray gun to achieve continuous operation.

GZ-3ER/SC refractory gunning machine spraying effect:

• Low rebound, low dust 
• Reduce the amount of water added
• Improve refractory compactness and strength
