Gravity-Drop Metal Detectors for your process

Inspect a free-falling dry-solids stream before the next process.

ADS ProScan gravity-drop systems inspect bulk solids passing vertically through an aperture and can pair detection with a reject arrangement. The chute, product flow, available drop height and reject timing need to be considered together.

Example: Inspect dry grain or another suitable ingredient before it enters a downstream process.

Also known as: Gravity-fall metal detectors, free-fall metal detectors, gravity-drop ProScan systems.

Use the free-fall transfer

locate inspection where the dry material can pass consistently through the head.

Review diversion

reject performance depends on the material flow and timing.

Fit the chute

transitions, cleanout and upstream flow behaviour affect the arrangement.

How It Works

1

Form a controlled falling stream

2

Inspect through the aperture

3

Divert affected material through the selected reject arrangement

Typical Materials & Industries

Grains and dry ingredients

review moisture, particle sizes and flow stability.

Spices and powders

product effect and buildup require product-specific testing.

Granular products

confirm stream dimensions and the practical reject quantity.

Application & Process Context

Product condition, moisture, pack or stream dimensions, belt speed or free-fall rate, metal targets, available space, and the required reject or stop response.

Grain is one example of a dry bulk material requiring a product-specific free-fall inspection review.

Configuration & Application Review

Equipment duty
Inspect a free-falling dry-solids stream before the next process.
Selection basis
Product condition, moisture, pack or stream dimensions, belt speed or free-fall rate, metal targets, available space, and the required reject or stop response.
Available configuration review
Aperture size, Inlet and outlet transitions, Reject arrangement, Contact construction, Controls and line interlocks, Cleanout and installation access.
Application verification
The inspection principle may be similar, but free-fall presentation and rejection are different. Review the available drop, product acceleration, flow variation and downstream connection before replacing equipment.

Options to discuss

  • Aperture size
  • Inlet and outlet transitions
  • Reject arrangement
  • Contact construction
  • Controls and line interlocks
  • Cleanout and installation access

Application Questions

Can this replace a conveyor detector directly?

The inspection principle may be similar, but free-fall presentation and rejection are different. Review the available drop, product acceleration, flow variation and downstream connection before replacing equipment.

What should I send RTS for a review?

Product condition, moisture, pack or stream dimensions, belt speed or free-fall rate, metal targets, available space, and the required reject or stop response.
