Screen Media

The media names, listed with their pages

PU screen and Polyurethane Products belong to the polyurethane line, described on the polyurethane screen panels page. Urethane Fine Screen belongs to the fine screen direction, described alongside the stack sizer panel page and the fine mineral screening guide. Special Screen Panels is a media name published by the supplier, and it is listed here without being expanded into a product page of its own, because the supplier website does not publish a separate page for it that this site can follow.

Self-Cleaning Screen is the media name for a surface shaped to resist clogging, and it is described in the media behaviour section below. Poly Ripple Screen is a media name published by the supplier, and it is listed here without being expanded into a product page of its own, for the same reason as Special Screen Panels. A buyer who needs either name should describe the screening task in the inquiry and name the media name, so the supplier can say which page or line it belongs to.

How media names relate to panel pages

Media names and panel pages overlap but are not identical. A media name describes a surface type, while a panel page describes a panel form and a panel task. PU screen as a media name and polyurethane screen panels as a panel page describe the same material from two angles: the media angle names the surface, and the panel angle describes the panel that carries it. A buyer should name both angles in the inquiry when both are under consideration.

The same discipline applies to fine screens. Urethane Fine Screen as a media name and the stack sizer panel form as a panel page describe fine screening from two angles. The media page lists the name, the panel page describes the form, and the fine mineral screening guide describes the task. Together they cover the fine direction without blurring one angle into another.

Self-cleaning media behaviour

A self-cleaning surface is shaped to resist clogging. When material tends to stick or pack, an ordinary surface can blind, and separation falls away even though the screen keeps vibrating. A self-cleaning surface sheds that material as it works, so separation continues under a feed that would blind an ordinary surface. That behaviour is described here in plain terms, because the supplier website does not publish item-by-item figures for this media name.

Self-cleaning behaviour is not a cure for every feed. A feed that is abrasive, or that varies widely, may need a different surface altogether, and a self-cleaning surface that suits one feed may suit another less well. A buyer should describe the feed honestly in the inquiry, including whether it tends to stick, so the supplier can answer about whether a self-cleaning surface fits the actual task.

Media choice across screening directions

Media choice varies by direction. Mining screening handles material from mineral extraction, where the feed varies and wear is part of the task. Mineral screening applications cover the wider set of separation tasks inside mineral processing, where the media must suit the material being separated. Coal processing screens serve the direction named on the rubber screen panel page, where the feed is coal and damp material is part of the task.

A buyer whose task spans two directions should read both application pages and describe both tasks in a single inquiry. A media type that suits mining screening may behave differently in coal processing, and the supplier can only answer about the combination if the combination is described. The media page and the application pages together help a buyer build that combined brief.

What this media index does not do

This page does not turn media names into product pages, and it does not publish specification figures for any media type. It does not describe a media name that the supplier website does not publish, and it does not borrow a specification from one media page and apply it to another. A buyer who needs a figure for a particular media type should ask for it in the inquiry, naming the media name and the task.

That limit is stated plainly so that a buyer does not mistake this index for a catalogue. The catalogue on this site is the set of published lines and the panel pages that describe them. Media names that have no page of their own belong in the inquiry as questions, not on this site as pages.

Questions that belong in a screen media inquiry

An inquiry about screen media should name the media type under consideration, describe the material being screened, and describe the machine the media surface will be fitted to. It should say whether the feed is dry or damp, whether it tends to cling or to blind openings, and what happens before and after screening. It should ask about availability, about certificates, and about timing, and it should confirm the minimum order quantity and the lead time before payment.

Those questions are gathered on the screen panel inquiry checklist page, which turns a media question into a brief. A brief written that way gives the supplier a task to answer, and it usually produces a reply that addresses the actual task, rather than a general description of a media range.

Questions to settle for a screen media inquiry

• Which media name is under consideration?
• What material is being screened, and does it tend to cling?
• What machine will the media surface be fitted to?
• Does the media name have its own panel page, or should it be asked about directly?
