■ Description

The GZ-3ER-GV Gunning Machine is a compact and multifunctional rotor-type dry spraying and pneumatic conveying machine designed for a wide range of construction and refractory applications. It can handle various materials, including refractory mixes, refractory castables, concrete, mortar, sand, pea gravel and crushed stone, making it suitable for both spraying and material conveying operations.

Compared with conventional gunning equipment, the GZ-3ER-GV features a lighter, more compact structure, making transportation, positioning and operation more convenient, especially on jobsites where working space is limited.

One of the key advantages of the GZ-3ER-GV is its flexible output adjustment. By installing rotors of different sizes and regulating the motor speed, the machine provides a theoretical output range of 0.5–3 m³/h. This allows users to select a suitable material delivery rate according to different spraying materials, construction conditions and project requirements.

With its compact design, adjustable capacity and broad material compatibility, the GZ-3ER-GV provides a versatile solution for refractory lining installation, furnace repair, concrete spraying, mortar application and pneumatic material conveying.

■ Application

The GZ-3ER-GV rotor-type gunning machine can be widely used for refractory installation, dry concrete spraying, mortar application and pneumatic material conveying. It is suitable for projects requiring flexible output and compact equipment, especially where construction space is limited or different materials need to be sprayed or transported. By selecting different rotor sizes and adjusting the motor speed, the output can be adapted to different project requirements, making the machine suitable for both low-output precision work and higher-capacity spraying or conveying applications.
