Material and feed context
State the material and known feed-size context from the current circuit.
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.
Buyers who know they need polyurethane media but have not identified the current family can compare polyurethane screen media families before beginning the application review.
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
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. These inputs narrow a technical review; they do not automatically determine the correct media or confirm compatibility.
- 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
Target separation
Describe the required product fraction or classification objective first.
Wet or dry condition
Record water, moisture, slurry, sticky material or dry-duty observations.
Deck position and duty
Identify the deck position and duty observed there.
Existing media and interface
Capture the current media format, aperture and visible fixing or tension details.
Current operating problem
Locate wear, blinding, pegging, drainage or replacement uncertainty.
Product-family review
Use installed-deck evidence to review a Modular, Dewatering or Tensioned path.
RFQ evidence and review
Provide photos, drawings or old samples, quantity and destination for review.
Screen media formats
Use the existing deck as the starting reference
Color does not confirm material, fixing or compatibility.
Modular polyurethane screen panels
For a module-based deck or local replacement, review the visible interface and support context before any fit is confirmed.
Review modular panel interface and deck context
Tensioned polyurethane screens
For a side- or end-tension deck, review the visible tension direction, hook-edge evidence and full-screen replacement reference.
Review tensioned screen and hook-edge evidence
Polyurethane dewatering screen panels
For drainage-oriented wet screening or a dewatering deck, review the current panel, deck evidence and fixing arrangement.
Review dewatering panel requirements for wet screeningRepresentative product views for selection and replacement discussion.
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
- Location of the current operating problem
When separate support, rail-protection or capping components are visible, review installation accessory requirements against the installed arrangement.
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
When the installed deck uses a flexible screening surface, review Flip-Flow panel requirements against the current panel and deck evidence.

Review process
Aggregate replacement review in five steps
This sequence describes the quotation and replacement review, not a manufacturing process.
- 01Review the existing screen and process duty.
- 02Identify the probable screen media format.
- 03Check dimensions, aperture and fixing arrangement.
- 04Confirm the quotation and inspection basis.
- 05Confirm packing and delivery requirements.
