Small size refractory concrete gunning machine

The small size refractory concrete gunning machine is a portable device designed specifically for spraying refractory materials over small areas. It is suitable for repairing linings of industrial furnaces and kilns, spraying anti-corrosion coatings on pipes, and constructing refractory layers on irregularly shaped structures. Its core features are its compact size (footprint < 2㎡, weight < 300kg) and flexible operation (mobile by a single person). It can quickly adhere refractory concrete (or plastic) to the work surface using high-pressure spraying, forming a dense, high-strength refractory protective layer (thickness 5-100mm, temperature resistance 1000-1800℃).
