Aggregate screening

Screen Media for Aggregate Screening

Aggregate screen media selection begins with the feed material, required separation, deck arrangement, operating condition and the existing fixing system.

Final configuration is reviewed against measurable references and operating information.

Process reference

Aggregate screening duties

Duties vary by circuit; one media format does not fit every condition.

  • Scalping before or between crushing stages
  • Product sizing and classification
  • Removal of oversize material
  • Separation into multiple product fractions
  • Wet aggregate screening
  • Washed sand and fines dewatering

Material retained on each deck exits as a separate fraction, while material passing through continues to the next deck. Actual deck count, flow arrangement and separation sizes depend on the screening circuit.

Selection inputs

Start with the process objective

Screen media should not be selected from the aggregate name alone. The target separation, moisture condition, deck position, fixing system and existing wear pattern must be reviewed together.

  • Feed material
  • Feed top size
  • Target separation sizes
  • Required product fractions
  • Wet or dry screening
  • Moisture or sticky material condition
  • Current screening problem
  • Deck position
  • Quantity

Screen media formats

Use the existing deck as the starting reference

Color does not confirm material, fixing or compatibility.

For existing modular decks, confirm module size, interface and support arrangement; compatibility still requires confirmation.

Tensioned polyurethane screens

For side- or end-tension deck replacement, confirm overall size, tension direction and hook-edge construction.

For washed sand or fines dewatering, confirm the slot reference, fixing arrangement and current deck.

Deck position

Information required by deck position

Record the duty and result required at each position; position alone does not determine configuration.

Feed end

Impact condition, feed distribution and the current wear pattern

Middle deck area

Target separation, material movement and pegging or blinding observations

Discharge end

Remaining oversize, product carryover and the local wear pattern

Lower deck

Finer separation requirement, moisture and buildup condition

Observed condition

Common screening problems to document

Record each problem and its location; no format resolves every issue.

  • Premature local wear
  • Pegging
  • Blinding
  • Broken or loose panels
  • Material bypass
  • Incorrect product fraction
  • Excessive carryover
  • Fixing-system damage
  • Uneven feed distribution

Installed reference

Existing deck and fixing information

Photographs and measurable details help distinguish process questions from replacement-fit questions.

  • Machine brand and model, if known
  • Number of decks and deck position
  • Current screen media type
  • Overall panel or screen dimensions
  • Support or rail spacing
  • Pin, bolt, rail, wedge or hook arrangement
  • Current aperture
  • Current material and wear pattern

Operating condition

Wet versus dry screening

Operating conditions guide review, not an absolute recommendation.

Wet screening

  • Water presence
  • Fines retention
  • Slurry or washed material
  • Drainage requirement

Dry screening

  • Moisture content
  • Dust condition
  • Sticky material
  • Pegging or blinding observations

Review process

Aggregate replacement review in five steps

This sequence describes the quotation and replacement review, not a manufacturing process.

  1. 01Review the existing screen and process duty.
  2. 02Identify the probable screen media format.
  3. 03Check dimensions, aperture and fixing arrangement.
  4. 04Confirm the quotation and inspection basis.
  5. 05Confirm packing and delivery requirements.
