Refractory gunning machines

The GZ-1.5ER is a wheeled electric rotor gunning machine. Despite the model designation, its product page publishes an output range of 0.7–3 m³/h, obtained through rotor selection and variable-frequency control. A pre-dampening nozzle wets material near the application point. The technical table lists horizontal and vertical conveying distances separately.

The GZ-3AR is an air-driven machine for refractory dry gunning. A five-cylinder piston air motor drives the feed rotor, and compressed air conveys material through a 38 mm hose. Its published output is 1–3 m³/h. A pre-dampening nozzle, hopper vibrator and dust collection bag are listed for the machine.

The GZ-3ER is an electric rotor machine for dry refractory gunning. Material is fed through a hopper and conveyed pneumatically to the application nozzle. Its published output range is 1–3 m³/h. A variable-frequency drive adjusts the rotor feed, while a pre-dampening nozzle introduces water near the application point. The listed configuration combines a 4 kW motor, solid wheels and a dust collection bag.

The GZ-3ER/S combines an electric rotor gunning machine with a water pump and automatic lubrication equipment. The published configuration has a 6.3 L rotor and a 1.5–3 m³/h output range. PLC control, a variable-frequency drive and an air-pressure sensor are described for delivery-line blockage management. Sector-shaped rotor openings distinguish this version from the standard GZ-3ER.

The GZ-3ER/SC uses a straight-chamber rotor and variable-frequency feed control for dry refractory gunning. The published range is 0–3 m³/h, with a maximum horizontal conveying distance of 200 m. A high hopper with an electric vibrator feeds the rotor. The page describes a dust cover, single-bolt clamping and alternative pre-dampening nozzle assemblies for different project configurations.

The GZ-5AR is a full-pneumatic straight-chamber rotor machine with a published output range of 1–5 m³/h. It uses a five-cylinder piston air motor and a 51 mm conveying hose. The source lists conveying-system air consumption and air-motor consumption separately, making air-supply confirmation an important part of selecting this model.

The GZ-5ER is an electric dry gunning machine with a published output range of 1–5 m³/h. Its 5.5 kW motor drives the feed system, while compressed air conveys material through a 51 mm hose. The source lists variable-frequency output adjustment, a hopper vibrator and a lightweight nozzle. The stated maximum horizontal conveying distance is 100 m.

The GZ-6AR/RD uses a 5 hp air motor to drive its material feed bowl. Compressed air also carries dry refractory material through a 38 mm hose to the nozzle, where water is added. The machine has 16 feed-bowl pockets and a published maximum output of 6 m³/h. The product page states that the compressor is supplied separately.

The GZ-6DR/RD uses an 8.2 kW diesel engine to rotate a 16-pocket material feed bowl. Dry material enters an 80 L continuous-feed hopper, passes through the feed bowl and is carried by compressed air through a 38 mm hose. Water is introduced at the nozzle. The published maximum output is 6 m³/h; an external air compressor is still required.

The GZ-9ER is a straight-chamber rotor machine with a published electric-drive output range of 3–9 m³/h. Its technical table lists a 7.5 kW motor, a 64 mm hose and a maximum aggregate size of 20 mm. Variable-frequency feed control, hopper vibration and a pre-dampening nozzle are described. The larger delivery configuration should be matched to the project air supply.
