Refractory Gunning Machine

Refractory gunning machine uses high-pressure spraying of refractory materials to quickly repair the refractory layer of high-temperature components such as kiln linings, preheaters, and coolers. Their core advantages lie in efficient repair, reduced downtime, and lower labor intensity. They are particularly suitable for partial or overall refractory layer maintenance of equipment such as rotary kilns, decomposition furnaces, and grate coolers in cement plants.

250kg capacity refractory mixer and gunning machine is the specialized piece of equipment used in industrial applications—particularly in steel, cement, petrochemical, and power generation industries—for mixing and applying refractory castables or gunning mixes onto furnace linings, ladles, kilns, or other high-temperature structures.

Today, our factory shipped four GZ-3ER refractory gunning machines. These gunning machines use compressed air to spray a precisely proportioned mixture of refractory materials at high speed, forming a refractory coating on the surface being sprayed. Their significant advantages, including rapid application speed, high efficiency, and high-quality work, have led to their widespread adoption. Refractory gunning machines are primarily used in the following applications:
1. Metallurgical Industry: Hot and cold repairs of blast furnaces, ladles, and converter linings.
2. Building Materials Industry: Refractory repair of cement kilns and glass kilns.
3. Power Industry: Thermal insulation spraying of boiler linings.
4. Construction and Mining: Tunnel support, slope protection, and fireproof coating of steel structures.
5. Decoration Engineering: Relief coatings, handicraft spraying, and rockery shaping.

The GRM 100kg, 250kg, 300kg, 500kg, 750kg, 800kg, and 1000kg Refractory Castable Pan Mixer features a compact design and full functionality. It is equipped with powerful performance and operating technology. The refractory pan mixer can be used for both castable and dry mortar refractory. Inside the mixer, there are very wear-resistant liners, extending the machine’s life.
The 100kg Refractory Castable Pan Mixer is suitable for laboratory use and small casting production. The 250kg Refractory Castable Pan Mixer is suitable for steel structure fireproofing and small kiln repair. The 500kg Refractory Castable Pan Mixer is suitable for industrial kiln lining and pipe wrapping. The 800kg Refractory Castable Pan Mixer is suitable for large ladle lining repair and blast furnace hot air duct construction. The 1000kg Refractory Castable Pan Mixer is suitable for laboratory use and small casting production. The Mixer is suitable for cement rotary kiln linings and waste incinerator casting.

Refractory gunning machines for repairing EAF use compressed air or a mechanical pump to mix refractory materials (such as magnesia and alumina-magnesia gunning materials) with water or a binder, then spray them at high speed onto the worn areas of the electric arc furnace lining, forming a dense repair layer. For electric arc furnace (EAF) gunning repairs, we recommend using refractory gunning machines with high-pressure output, wear-resistant nozzles, automated control, and explosion-proof design. Their core function is to repair the furnace lining by spraying refractory materials at high pressure, and key parameters must be compatible with the high-temperature, high-wear environment of the EAF.

Small guniting machine for refractory works can usually be classified as a dry mix refractory gunning machine or an electric refractory gunite machine. Its core function is to spray dry powdered refractory materials (such as refractory mud and castables) at high speed onto the construction surface through compressed air or electric drive to form a refractory protective layer.

Electric motor dry mix refractory gunning machine is an electric device designed specifically for refractory spraying. It is driven by a motor to achieve efficient and precise construction. It is widely used in industrial furnace lining repair, boiler refractory layer construction, and concrete building repair.

Gaode Equipment is a professional refractory equipment manufacturer and supplier from China. We can provide you with electric, pneumatic and diesel-powered refractory shotcrete machines of various displacements and refractory mixers with mixing capacities of 100kg, 200kg, 250kg, 300kg, 500kg, 750kg, 800kg and 1000kg. They are widely used in the construction and preparation of high-temperature industrial refractory materials.

A refractory shotcrete machine (also commonly referred to as a refractory gunning machine or shotcreting machine) is a specialized piece of equipment used to apply refractory materials—such as castables, plastic refractories, or gunning mixes—onto the internal surfaces of high-temperature industrial vessels like furnaces, kilns, ladles, and incinerators.

An electrical refractory gunning machine is a specialized piece of equipment used in high-temperature industrial applications, such as steelmaking, cement production, and other metallurgical processes. It is designed to apply refractory materials (heat-resistant linings) to the internal surfaces of furnaces, kilns, ladles, and other vessels that are exposed to extreme heat.
