■ Description

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

$whole set refractory gunning machine$

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.

$Dry Refractory Gunite Machine$

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.

■ Application

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.

Application scenarios of GZ-3ER/SC dry mix refractory gunning machine:

$steel plant refractory gunning machine$

1. Steel Industry

Converter and Electric Furnace Maintenance: Magnesium or aluminum-magnesium dry materials are sprayed to repair easily worn areas such as the furnace mouth and furnace cap, reducing downtime.

Ladle Lining Repair: High-aluminum or corundum spray coatings are used to create a high-temperature, erosion-resistant layer, extending the service life of the ladle.

Blast Furnace Shaft Repair: Dry gunning machines can spray aluminum silicate or carbonaceous materials to quickly repair high-temperature areas such as the furnace belly and furnace waist.

2. Non-ferrous Metal Smelting

Aluminum Electrolytic Cell Lining: Spraying alumina-based dry materials creates a corrosion-resistant layer, reducing the risk of electrolyte leakage.

Copper/Lead Smelting Furnaces: Gunning magnesium-chromium materials resists slag corrosion and improves furnace stability.
