Screener Mesh Sizes — Recommendation Guide

Choose the right DeSite mesh for topsoil, gravel, compost, mulch, farm filling and aggregate. Charts below are tailored for Pro Screen Australia operators — imperial openings (industry standard) with approximate metric context where helpful.

Base Mesh Charts

Use these square and elongated charts as a starting point. Final product size is typically a little smaller than the mesh opening, depending on material and moisture.

Which machine uses this mesh? Most openings fit the SLG-68V, SLG-78VF and SLG-108VFRB Proscreens; coarse square mesh also suits the Static Grizzly. SLG-68V · SLG-78VF · SLG-108VFRB · Static Grizzly

Topsoil and Triple Mix

Topsoil is in demand and profitable. Some customers want a very fine finish; others prefer commercial-grade product at a sharper price point.

Which machine uses this mesh? Fine top dressing and commercial triple-mix: SLG-68V, SLG-78VF or SLG-108VFRB with elongated or square soil mesh. SLG-68V · SLG-78VF · SLG-108VFRB · Topsoil screening

Compost

Compost can be finished as a top-dressing fertiliser / soil builder, or blended with sand and topsoil to create triple mix.

Which machine uses this mesh? Compost and organics: SLG-68V or SLG-78VF with elongated soil mesh; step up to SLG-108VFRB for yard volume. SLG-68V · SLG-78VF · SLG-108VFRB

Wood Mulch

Wood mulch is a light product that moves differently across the deck than soil or aggregate. Run a slightly larger mesh. Many operators screen out fines and mix them into topsoil for slow-release decomposition — a practical way to recycle wood fines.

Which machine uses this mesh? Wood mulch: SLG-78VF or SLG-108VFRB; Static Grizzly for coarse first-pass oversize. SLG-78VF · SLG-108VFRB · Static Grizzly

Farm Gravel, Cow Races and Filling

Immediate market offer: 100 mm mesh first to knock off oversize, then a 50 mm or 3 inch (~75 mm) secondary to make filling material. Riverbed stone that has rounded on farm makes stronger cow races than sharp crushed product. Exact 70 mm is not a listed stock square — 50 mm and 3 inch (~75 mm) are the nearest DeSite openings; 70 mm can be special-ordered.

Which machine uses this mesh? Farm river gravel: Static Grizzly or dual-78 setup for oversize, then a Proscreen for filling — see the farmers page. Static Grizzly · SLG-78VF · SLG-108VFRB · Farmers

First pass — oversize

Lead with 100 mm / 4″ on a Static Grizzly or Proscreen. Same opening contractors already spec for oversize gravel.

Aggregate Products

Wider square mesh (including 2″, 3″ and 4″ grizzly openings) is commonly sought for durable aggregate separation, road base and recycled materials. Photos show typical finished grades for visual comparison.

Which machine uses this mesh? Road metal, pea gravel and recycled concrete: Static Grizzly for oversize, SLG-78VF or SLG-108VFRB for finished grades. Static Grizzly · SLG-78VF · SLG-108VFRB · Aggregate screening

Pea Stone

Often used in playgrounds or for decoration. Pea stone usually commands a premium because most aggregate is crushed and too sharp.

Base Rock Gravel

Separating smaller gravel makes a more stable road base. Fines can then be spread on top of the base course for a gradeable surface.

Ground Asphalt

Screening recycled asphalt from repaving projects is popular. Fines often go on driveways; larger material suits roads and yards with heavier traffic.
