How it works & where it is used
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.
Refractory contractors; steelmaking, non-ferrous processing, cement and boiler maintenance.
Designed around the material flow
- Variable-frequency adjustment of material feed.
- Self-leveling single-bolt clamping arrangement.
- High hopper with electric vibrator and dust cover.
- Alternative rotor bodies and steel rotor plates.
- Solid wheels and a 38 mm conveying hose.
- A 30 bar water pump is described in the feature list; confirm inclusion.
Feed adjustment can accommodate localized work and changing application rates. The clamping arrangement provides access to sealing components, while nozzle alternatives allow the water introduction arrangement to be selected for the material. Dust and rebound depend on the installed setup and operating conditions.
Structure & installation
Installation planning: Confirm compressor delivery, hose routing, nozzle water supply and drive requirements. Conveying distances depend on the actual installation.
Pending confirmation. A model-specific installation drawing, interface dimensions and electrical diagram have not been supplied. Request these for the offered configuration. Product photographs do not replace installation drawings.

Air, power & conveying boundaries
Air-pressure values describe the pneumatic system, not the pressure of a hydraulic pump. Do not assume maximum output and maximum conveying distance can be achieved simultaneously.
Information needed for selection Specify the refractory formulation and longest hose route. Confirm compressor pressure at the machine, water supply and the selected nozzle before approving a 200 m layout.
Pending confirmation. A verified performance curve or material trial record is not available. Maximum values must not be assumed to occur simultaneously.
Configuration & maintenance
Items requiring confirmation Rotor, coupling and nozzle variants are options, not a promise that every alternative is included. The published zero lower limit describes adjustment range; it is not productive delivery at zero speed.
Pending confirmation. Confirm the standard accessory list, consumable parts and operating instructions for the exact build. Confirm the hose diameter, hose length, nozzle and whether a water pump is included.
Documentation & evidence
Pending confirmation. No model-specific independent test report or verified project case has been supplied for this representative page. Product certification applicability, document validity and public display permission remain to be checked. No certification or service-life guarantee is implied.
Quotation & support scope
Packaging, minimum order quantity and lead time: Not established in the cited technical data. Request the packing method, packed dimensions, gross weight, order quantity and delivery schedule in the quotation. Machine dimensions and weight are not shipping measurements.
Also confirm the standard accessory list, consumable parts, warranty, commissioning support, packing, MOQ and lead time. No certification, factory production capacity or quantified service-life claim is added without supporting records.
