Tracked Mobile Screening Plants – Engineered for Reliable Aggregate Grading in the Field
As an engineer who’s spent years designing and commissioning mobile crushing and screening trains, I can tell you that the screening stage is where a lot of projects make or lose money. Poor separation means off-spec aggregates, wasted material, or extra processing steps. Our tracked mobile screening plants are built to deliver consistent, high-quality grading right at the source – whether you’re producing road base, concrete sand, or recycled aggregates from C&D waste.
These are heavy-duty crawler-mounted units, typically configured with 2- or 3-deck inclined screens, handling real-world capacities from 100 to 400 TPH depending on material density, feed gradation, and screen media selection. In our standard hard rock setups (paired with jaw and cone crushers), a 3-deck screener easily produces clean fractions like 0-5mm, 5-20mm, and 20-40mm from granite or basalt feeds. For softer limestone or recycling lines, we optimize for higher throughput with anti-clogging media.
Key Engineering Features That Matter on Site:
- Screen Box Design: Heavy-duty inclined (or horizontal on request) with adjustable amplitude, speed, and throw angle. This gives you flexibility to tune for sticky materials or maximize fines removal without blinding.
- Crawler Chassis: Full hydraulic drive tracks with excellent gradeability – we’ve seen these units climb 20-30% slopes in wet quarries without slipping. No need for separate transport; just drive from stockpile to stockpile.
- Hydraulic Folding System: Side and fines conveyors fold quickly for transport (overall dimensions fit standard lowbed trailers). Setup time is typically under 30 minutes with one operator.
- Modular Integration: Easy closed-circuit return conveyor to feed back oversize to the cone or impact crusher. Optional grizzly pre-screen and magnetic separator for rebar removal in recycling applications.
- Durability Focus: Reinforced frame, high-quality bearings, and centralized lubrication. Every unit goes through full-load run-in testing at our factory – 8+ hours under simulated quarry conditions – so vibration issues or alignment problems are caught before shipment.
- Control System: PLC-based with remote diagnostics option. Operators can monitor screen load, adjust parameters on the fly, and get fault alerts via app.
In practice, these screeners shine when integrated into our complete mobile lines – for example, a 250-300 TPH hard rock train (mobile jaw + SY-HP300 cone + 3-deck screener) delivers cubic aggregates with minimal recirculation. For C&D waste, add the magnet and you’ve got clean recycled product ready for resale.
Compared to European units, our design prioritizes structural integrity (drawing from military manufacturing standards) while keeping weight and cost down – meaning similar screening efficiency and uptime, but faster ROI for mid-sized operations.
