CQ-918
Chaoqiang
A conveyor metal detector with pneumatic pusher / flap rejection, phase-tracking intelligence and a customizable detection tunnel — catches ferrous, non-ferrous and stainless contaminants before they reach your customers.
Detection sensitivity is validated per tunnel height. The 918 accepts fully customized tunnel dimensions, rejection types and storage capacity for your specific production line.
| Tunnel Height (mm) | 80 | 120 | 150 | 180 | 200 | 250 | 300 |
|---|---|---|---|---|---|---|---|
| Fe (φmm) | ≥0.5 | ≥0.6 | ≥0.7 | ≥0.8 | ≥1.0 | ≥1.2 | ≥1.5 |
| Non-Fe (φmm) | ≥0.8 | ≥1.0 | ≥1.0 | ≥1.5 | ≥2.0 | ≥2.0 | ≥2.0 |
| 304 SUS (φmm) | ≥1.0 | ≥1.2 | ≥1.5 | ≥2.0 | ≥2.0 | ≥2.5 | ≥3.0 |
Newly Upgraded · Performance Enhancement
Every component is selected to keep your line running — precise detection, fewer false rejects and less operator intervention.
All-digital intelligent control board with LCD display, direction pad and six dedicated function keys. Set products, sensitivity and running modes directly on screen — no PC or specialist required.
Advanced signal analysis locates the contaminant exactly on the belt, so the reject action is clean, repeatable and wastes no good product.
High-response infrared sensing triggers the reject unit the moment a contaminated item reaches the reject point — accurate every cycle.
Digital core built on original Japanese imported chips — the sealed coil keeps readings stable and immune to interference.
One-touch auto learning scans your product and sets the optimum sensitivity automatically — no manual parameter tuning required.
Mirror-polished 304 stainless steel frame stands up to moisture and washdown chemicals — no rust, no oxidation, long equipment life.
Precision detection and reliable rejection start here — the head and belt are engineered to hold sensitivity at full line speed.
The detection aperture is wound with high-temperature 3.5 copper wire in a full 360° loop and sealed once with resin — giving a stable magnetic field, strong immunity to interference and a long working life.
Food-grade hygiene conveyor belt with a pneumatic pusher reject unit — contaminated products are pushed off the line into a stainless steel collection chute. Safe to place on any assembly line.
Attention to every mechanical detail keeps the 918 stable in continuous operation and simple for your operators to maintain.
1 Guides the belt so it runs straight and true — smooth tracking with no deviation.
2 Protective guard with pinch-point warning keeps operators safe around moving rollers.
3 Full-digital intelligent interface with LCD display, direction pad and function keys for quick setup and product switching.
4 Advanced 304 stainless steel — rust resistant and oxidation resistant in humid environments.
5 Big mushroom-style emergency stop button gives operators instant, reliable machine shutdown.
6 Tool-free modular latch opens panels quickly — maintenance and cleaning made simple.
The upgraded 918 adds production-grade data tools: phase tracking, automatic balance correction and FPGA digital processing — standard on every unit.
Maintains stable high-precision detection capability as operating conditions change during production.
Automatically adjusts internal compensation according to changes in product effect — no manual re-tuning between batches.
Keeps the detection coil in balance automatically, guaranteeing machine service life and extending operation time.
High-performance FPGA with DDS technology and advanced DSP data processing — higher digital level and stronger anti-interference performance.
Store up to 55 product parameter sets, with optional USB and Ethernet data interfaces for line integration and traceability.
IP65 waterproof grade can be customized according to factory requirements for washdown environments.
From bakeries to seafood plants — proven on the line across food, aquatic and poultry production.
We are a source manufacturer of inspection equipment — the 918 is built, tested and batch-run in our own plant.
We machine, assemble and inspect every unit in our own factory — factory-direct pricing with full quality control.
Tunnel size, belt speed, reject type and parameter storage are all configured around your product and production line.
Multiple 918 units running side by side in food plants — stable performance under continuous duty.
55 product parameter groups with optional USB / Ethernet data interfaces — meet audit and quality traceability requirements.
Meet the Chaoqiang team at exhibitions worldwide — and bring your samples to test on the machine live.
