How it works & where it is used
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.

Designed around the material flow
- Straight-chamber rotor with variable-frequency control.
- Bag cutter and flat hopper with vibrator.
- Pre-dampening nozzle and blast rubber conveying hose.
- Dust collection bag and cleaning air gun.
- Solid wheels for repositioning; couplings and clamps listed.
Adjustable feed lets the operator match material delivery to the repair area. Hopper vibration assists loading, and nozzle-side wetting permits water adjustment during spraying. These features support process control; no fixed rebound reduction or lining-life improvement is guaranteed.
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 Provide material grading, target output, hose route, available compressor capacity and electrical supply. Check the actual conveying distance against the material and hose arrangement.
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 Confirm the offered hose diameter, hose length, nozzle type and whether the water pump is included. The page names ABB for the drive; verify the supplied brand before purchase.
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.
