Mobile Screener Applications: What Komplet Screeners Actually Process On-Site

Cody Price - Operations Manager at Komplet America

Mobile screeners process specific feed materials into spec cuts on-site. The right model for any given operation depends on the dominant feed material, the throughput requirements, and the operational profile. Komplet America builds two screener product lines that cover most contractor-scale and small commercial screening applications: vibrating scalping screens (Kompatto 221, 5030, 124) for hard dry C&D, RCA, aggregate, and dry-soil work, and trommel screens (K-TS 30, 40) for compost, topsoil, mulch, and organic feedstock work.

This guide walks through the actual applications Komplet America screeners handle on-site, the operational profile of each application, and the right Komplet model for the work. The goal is honest application matching — buying the right screener for what your operation actually does, rather than oversizing capacity you will not use or undersizing capacity that creates a workflow bottleneck.

Eight Mobile Screener Applications Komplet Equipment Handles

1. RCA Spec-Cut Production from Crusher Output

The most common contractor application. Demolition concrete that has been crushed through a Komplet jaw crusher discharges as crusher run — well-graded mix from fines through the maximum spec size set by the operator-adjusted closed-side setting. Customers and projects need the crusher run separated into spec cuts (3/4″ base, 1-1/2″ drainage, fines, oversize) for resale or project use, and that’s where the screener does the work. Vibrating scalping screen with two-deck mesh configuration produces three discrete output streams in a single pass. Match the screener throughput to the crusher’s: K-JC 503 (34 tph) or K-JC 604 (55 tph) pair naturally with the Kompatto 221 (90 tph); K-JC 704 PLUS (90 tph) pairs naturally with the Kompatto 5030 (280 tph); K-JC 805 (160 tph) pairs naturally with the Kompatto 5030 or Kompatto 124 (350 tph).

2. Asphalt and RAP Spec-Cut Separation

Recycled asphalt pavement (RAP) follows the same workflow as concrete RCA — the asphalt feed runs through a Komplet jaw crusher, discharges as crusher run, and gets separated into spec cuts via a vibrating scalping screen. For asphalt plant feed where particle shape matters (cubical aggregate produces better hot-mix performance than the elongated particles a typical jaw crusher produces), operators run a Komplet jaw crusher for primary reduction and the K-IC 70 compact impact crusher for secondary reduction; the K-IC 70 produces premium cubical aggregate ideal for spec RAP applications. Vibrating scalping screen handles both the primary RAP separation and the cubical RAP from the K-IC 70 secondary stage.

3. Soil Screening on Excavation and Site-Prep Projects

Excavation projects routinely produce soil that needs screening — separating fill grade from oversize rock, rejected debris, and root mass. For dry to moderately moist soil (typical excavation conditions in most markets), a vibrating scalping screen handles the work efficiently with the throughput, deck count, and oversize handling that excavation projects need. Match the screener to the excavation throughput requirement: smaller jobs fit the Kompatto 221; mid-range and larger excavation work fits the Kompatto 5030 or Kompatto 124. For excavation in regions with wet, clay-rich soils where the soil arrives at the screener with high moisture and clay content, a trommel screen (K-TS 30 or K-TS 40) handles the wet soil more forgivingly than a vibrating scalping screen — choose based on the dominant soil profile across the project pipeline.

4. Aggregate Yard Spec-Cut Finishing

Aggregate yards finishing crusher output, recycled aggregate, or virgin material into spec stockpiles use vibrating scalping screens to separate output into multiple cuts that customers buy by spec size. Yards selling 3/4″ base, 1-1/2″ drainage, fines, and oversize all from the same incoming material need two-deck screening with mesh selection matched to the customer specs. The Kompatto 5030 (Komplet America’s best-selling screener) covers contractor-scale and small commercial yard finishing throughput; the Kompatto 124 covers commercial-scale yard operations producing higher-volume spec stockpiles.

5. Compost Production and Organic Feedstock Screening

Compost is a meaningfully different feed material from C&D — moisture content matters, fibrous strings catch and bridge on flat decks, and irregular particle shapes don’t behave like dry rock material. For compost feedstock screening, finished compost grading, and similar organic processing, trommel screeners handle the material more forgivingly than vibrating scalping screens. The K-TS 30 fits compact contractor-scale compost operations and modest production volumes; the K-TS 40 covers higher-throughput compost and landscape supply operations. The trommel’s rotating drum tumbling action keeps compost feedstock moving and clearing rather than bridging on a flat deck.

6. Topsoil Screening for Landscape Supply

Topsoil screening for landscape supply, garden centers, and contractor sales depends on the topsoil’s moisture and clay content. Dry topsoil with low clay content runs efficiently through vibrating scalping screens (Kompatto 221 for compact landscape supply, Kompatto 5030 for higher-volume operations). Topsoil with high moisture, high clay content, or significant fibrous root content runs better through trommel screens (K-TS 30 for compact operations, K-TS 40 for higher-throughput). Many landscape supply operations producing topsoil across seasonal moisture variation run both technologies side by side.

7. Mulch Grading and Hardscape Material Production

Mulch grading — separating fine mulch, mid-fraction mulch, and oversize bark/wood chunks — runs better through trommel screens than vibrating scalping screens because mulch’s fibrous strings would bridge and catch on flat decks. The K-TS 30 and K-TS 40 cover mulch grading workflows for landscape supply operations. On the hardscape side, decorative aggregate and specialty stone production runs through vibrating scalping screens (Kompatto 221 for small batches, Kompatto 5030 for larger operations) — the dry stone material runs efficiently through the vibrating mesh.

8. Brick, Block, and Mixed Hard C&D Rubble Separation

Brick, concrete block, masonry rubble, and mixed hard C&D feed run through vibrating scalping screens efficiently — the dry hard feed material is exactly what vibrating scalping is engineered for. Crushed brick rubble separates into spec cuts cleanly through two-deck Kompatto screen meshes. For operations processing demolition brick and masonry alongside concrete (typical contractor demolition work), the same crusher-and-screener spread that handles concrete RCA handles brick and block rubble — Komplet jaw crusher → Kompatto vibrating scalping screen → K-TC 460 tracked mobile conveyor for stockpile management.

Honest Scope: Applications Komplet Screeners Do NOT Handle

Komplet screeners cover the contractor-scale and small commercial applications above. They do not handle every screening application, and being honest about scope helps customers buy the right equipment for what they actually do:

Industrial-scale fixed-plant screening — operations requiring 500+ US tph sustained, multi-shift continuous production, or industrial throughput beyond the Kompatto 124’s 350 tph envelope need fixed-plant industrial screening equipment outside Komplet’s compact-mobile category.
Quarry primary feed at industrial scale — most quarry primary screening operations need fixed-plant industrial screening equipment that Komplet does not sell. The K-JC 805 + Kompatto 5030 or Kompatto 124 spread can handle some smaller quarry secondary or finishing applications, but most quarry operations are outside Komplet’s category.
Municipal solid waste (MSW) and household garbage screening — Komplet does not provide waste removal services and does not process MSW. MSW recycling requires purpose-built equipment from manufacturers focused on that recycling category.
Specialty filter media and water filtration aggregate production — specialty applications requiring tight clean-aggregate gradations typically use specialty fixed-plant equipment, not compact mobile screening.
Glass recycling, e-waste, tires, paper, cardboard, textiles — each waste stream has dedicated recycling pathways with purpose-built equipment Komplet does not sell.

Frequently Asked Questions

Which Komplet screener is right for crushing-and-screening RCA production?

For typical contractor demolition and on-site C&D recycling, the K-JC 704 PLUS jaw crusher paired with the Kompatto 5030 screener and a K-TC 460 tracked mobile conveyor is Komplet America’s most popular crushing-and-screening combination. K-JC 704 PLUS is the best-selling crusher; Kompatto 5030 is the best-selling screener. Smaller operations fit the K-JC 503 or K-JC 604 with the Kompatto 221; commercial-scale operations fit the K-JC 805 with the Kompatto 5030 or Kompatto 124.

Which Komplet screener handles compost?

Compost screening uses trommel screeners. The K-TS 30 fits compact contractor-scale compost operations and modest production volumes; the K-TS 40 covers higher-throughput compost and landscape supply operations. The trommel design handles the moisture, fibrous content, and irregular particle shapes of compost feedstock more forgivingly than vibrating scalping screens.

Can I screen topsoil with a vibrating scalping screen?

With limitations. Vibrating scalping screens handle dry, low-clay topsoil reasonably well. They struggle when topsoil arrives with high moisture, high clay content, or significant fibrous root content — the material sticks to the deck, blinds the mesh, and forces operators into clearing cycles. For consistent topsoil production across seasonal moisture variation, a trommel screener (K-TS 30 or K-TS 40) is typically the right tool. Many landscape supply operations run both vibrating scalping (for dry hardscape stone) and trommel (for wet topsoil) side by side.

How is the Kompatto 5030 throughput rated?

The Kompatto 5030 is rated up to 280 US tph throughput. Throughput depends on material type, moisture content, screen mesh selection, and feed gradation — published TPH figures reflect optimal operating conditions, and real-world utilization typically runs at a meaningful fraction of theoretical capacity. Build a reasonable margin above your sizing math when specifying a screener for sustained throughput requirements.

Do Komplet screeners run standalone, or do they need to pair with a crusher?

Both. Screeners pair with Komplet jaw crushers for crusher-output spec separation, but they also run standalone for material that doesn’t need crushing first — pre-sized soil, compost, topsoil, mulch, RCA from a stockpile, aggregate yard product separation. A loader feeds the hopper directly, and the screener separates the material into spec cuts. Standalone screening is particularly common for landscape supply, compost operations, and yard finishing.

Can I change screen mesh to produce different spec cuts on the same machine?

Yes. Screen mesh and screen panels are interchangeable on Komplet vibrating scalping screens. Operators select the mesh based on the day’s target output spec — different mesh selections on the same machine produce different spec cuts. Trommel drum sections are also typically configurable for different mesh sizes. The same screener handles different applications by changing the mesh selection between operations.

What size jobsite is too small for a Komplet screener?

Komplet’s smallest self-propelled scalper, the Kompatto 221 (~7,275 lb operating weight), and the K-TS 30 trommel (~8,818 lb) are sized for tight-access urban contractor work and compact landscape supply operations. For very small operations producing only occasional material, rental through an authorized Komplet dealer is typically the right starting answer rather than committing to ownership upfront.

Where can I see Komplet screeners running on actual material?

Final Thoughts

Mobile screener applications fall into a clear pattern: hard, dry feed materials (concrete RCA, asphalt, brick, hardscape stone, dry soil, dry aggregate) run through vibrating scalping screens; wet, sticky, fibrous, irregular feed materials (compost, topsoil with moisture, mulch, organic feedstock) run through trommel screens. Komplet America’s lineup covers both technology categories — Kompatto 221, 5030, 124 for vibrating scalping; K-TS 30, 40 for trommels — with verified specifications, verified pricing, and the same authorized service network across North and Central America.

Match the screener to the application: the right model for the work delivers the throughput and spec discipline customers and projects expect; the wrong model produces frequent operator clearing cycles, contaminated output, and operational frustration. For operations whose project pipeline spans multiple application types — a recycling yard with both C&D and topsoil, or a landscape supply operation with both decorative aggregate and compost — running both technologies side by side is often the right answer. Talk through your specific feed material with Komplet America or your authorized Komplet dealer before specifying.
