Super Absorbent Polymer for moisture reduction in iron ore and coal

SNF Super Absorbent Polymer (SAP) takes up excess moisture in iron ore, coal and bulk minerals, so wet, sticky material becomes drier and free-flowing.

Wet iron ore and coal cause a chain of problems: hang-up in chutes, carry-back on belts, spillage in transport and lost value in the product. Removing the excess moisture solves them at source.

Super Absorbent Polymer is a cross-linked polymer that absorbs and holds large amounts of water. We supply it with our partner SNF Water Science.

What SAP does

  • Absorbs excess moisture quickly
  • Improves flowability and handling
  • Reduces material losses and spillage
  • Reduces stickiness and belt carry-back
  • Improves storage and transport efficiency

Where it is used

  • Iron ore: moisture control for easier handling and transport
  • Coal: less stickiness, better flow
  • Minerals and ores: suitable for a range of bulk minerals
  • Stockyards: maintains material condition in storage
  • Conveyor systems: less spillage and carry-back
  • Road and rail transport: better loading and unloading

How it fits with our wear solutions

Moisture control and liners work together. SAP makes the material easier to handle; low-friction liners and smooth wear plate keep what remains sticky moving. We look at both when solving a flow problem.

Frequently asked questions

What is Super Absorbent Polymer?

A cross-linked polymer that absorbs and holds large amounts of water. In bulk handling it is dosed into wet material such as iron ore or coal to take up excess moisture.

How does SAP reduce moisture in iron ore?

The polymer absorbs free moisture on the ore, turning wet, sticky material into drier, free-flowing material that handles and transports better.

Can SAP be used on coal?

Yes. SAP reduces stickiness and improves the flow of wet coal in handling and transport.
