Bulk Material Handling & End-of-Line — Quality Inspection

Metal Detector — Gravity-Fall & Inline Conveyor

Also known as: Inline metal detector, gravity fall metal detector, channel metal detector, tunnel type metal detector
ENZAC supplies metal detectors in two configurations: gravity-fall type for bulk stream inspection before bagging, and inline conveyor type for finished packaged product inspection. Both detect ferrous, non-ferrous, and stainless steel at high sensitivity.
Types: Gravity-fall / Inline conveyor
Detects: Fe / Non-Fe / SS
IP rating: IP65/66/69K
Auto-reject: Yes
Frequencies: 3 user-selectable

ENZAC gravity-fall metal detector for bulk stream inspection

Configuration 1: Gravity-Fall (Bulk Stream)

Installed inline in the bulk conveying stream — above the bagging hopper or below a silo outlet. Material falls freely through the detector aperture. Detects ferrous, non-ferrous, and stainless steel in unpackaged bulk material. Available in gravity-fall and tunnel-type configurations.

Best applications: fertilizer, oleochemical, food ingredients, chemicals, plastics — where contamination must be caught in the bulk stream before packaging.

Configuration 2: Inline Conveyor (Packed Product)

Installed on the takeaway conveyor after bag closing — inspects filled, sealed bags at full production speed. ENZAC's premium-class inline detector delivers 30% better sensitivity than entry-level tuned detectors. Auto-reject triggers pneumatic pusher, air-blast, or divert conveyor on detection.
