- Conveying hose ID
- 64 mm
How it works & where it is used
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.
Steel mill refractory installation and other compatible dry gunning projects.
Designed around the material flow
- Variable-frequency feed adjustment.
- Bag cutter and hopper with electric vibrator.
- Dust collection bag and cleaning air gun.
- Protective frame and heavy-duty solid wheels.
- Lightweight nozzle, couplings and blast hose.
- A 30 bar water pump is described; verify the supply scope.
The wider published output range supports projects that need more material delivery than the smaller GZ machines. Feed adjustment allows matching to the spraying task. The maximum output and aggregate limit do not guarantee suitability for every refractory formulation.
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 the required application rate, particle grading and hose route. Check compressor output and the handling plan for the 900 kg machine before final selection.
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 These specifications apply to the electric-drive configuration. The description mentions an air-drive alternative, but it must not inherit the electric motor or air-consumption figures without confirmation.
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.
