Question 1

What is a Foreign Particle Detection System?

Accepted Answer

A Foreign Particle Detection System is an AI-powered, multi-sensor vision platform that automatically detects and classifies unwanted contaminants metal fragments, stones, wood, plastics, or biological matter on conveyor belts and in bulk material streams in real time. Helious's system is deployed across coal handling, cement production, steel raw material processing, and food-grade operations to protect downstream equipment, ensure product purity, and trigger instant isolation alerts before contamination spreads.

Question 2

What types of foreign particles can the system detect?

Accepted Answer

Helious's AI foreign particle detection system is trained to identify a wide range of contaminants including metallic tramp (iron bolts, wire fragments, excavator teeth), non-metallic objects (plastic bags, rubber belts, wooden planks), oversized lumps, and even biological contamination in food-grade conveyors. The multi-sensor fusion combining optical cameras, X-ray, near-infrared, and inductive sensors ensures detection across opaque, fine-grained, and reflective material streams in mining, cement, coal, and agro-processing industries.

Question 3

How does real-time AI inspection prevent equipment damage?

Accepted Answer

When the AI detection engine identifies a foreign object on the conveyor, it triggers an immediate automated alert to the control room and where configured activates a pneumatic rejection gate or conveyor stop to isolate the contaminated material before it reaches crushers, mills, or downstream processing equipment. This real-time contaminant detection for conveyors prevents catastrophic crusher damage, unplanned production shutdowns, and costly maintenance events that can cost lakhs per hour in idle plant time.

Question 4

What industries use foreign particle detection in India?

Accepted Answer

Foreign particle detection systems are critical in Coal Washeries and Thermal Power Plants (detecting rock and metal in coal feed), Cement Plants (protecting raw mills from tramp metal), Steel Plants (screening iron ore and scrap), Food & Grain Processing (ensuring FSSAI compliance for allergen and pest contamination), and Chemical Manufacturing. Helious's industrial contamination detection systems are deployed across India and the Middle East, serving clients including Coal India, Shree Cements, and Sohar Steel.

Question 5

How accurate is AI-based foreign particle detection vs traditional metal detectors?

Accepted Answer

Traditional metal detectors only identify ferrous and non-ferrous metals and generate high false-positive rates in magnetite-rich ores or wet coal. Helious's AI-based foreign particle detection system goes far beyond metal detection it visually classifies the object type, size, and position with up to 99%+ detection accuracy, including non-metallic contaminants that metal detectors miss entirely. This makes it a superior contamination inspection solution for bulk material handling in mining and cement plants.

Question 6

Can the foreign particle detection system be integrated with existing conveyor systems?

Accepted Answer

Yes. Helious's Foreign Particle Detection System is designed for non-invasive integration with existing belt conveyor systems without requiring major civil modifications. The camera and sensor arrays are mounted above the conveyor, and the AI engine connects to the plant's SCADA or DCS via standard Modbus, OPC-UA, or REST API interfaces. This plug-and-play AI contamination detection for conveyors allows most plants to go live within 24 weeks, with minimal production disruption during installation.
