Tracked and modular screens with scalping and finishing decks for aggregates, topsoil, coal and sand classification. Capacities from 200 to 500 TPH.
The sizing stage of a plant, or a standalone machine for aggregate, topsoil, coal and sand. Inclined decks for sticky, damp feed that would blind a horizontal screen; horizontal decks where headroom is limited and a lower feed height matters.
Compare the models in this line by capacity, feed size, discharge range, power and dimensions. A dash means the parameter is not listed for that model. Final specifications may vary by configuration and project requirements.

A screening plant earns its place two ways: as the sizing station of a crushing circuit, or as a standalone machine for aggregates, topsoil, coal and sand. What decides the configuration is not the tonnage but the feed — its moisture, clay content, and how fine the cut must be.
Inclined decks move material fast and suit high-tonnage aggregate screening. Horizontal decks keep material on the mesh longer, which is what fine cuts and damp, clay-bearing feed need, and they suit sites where headroom or feed height is limited. For feed full of soil and oversize lumps, a scalper ahead of the crusher takes the punishment instead of your cone or impact chamber.
Common questions about model selection, price factors, applications and quotation requirements.
Yes — by swapping the screen panels, not the machine. The same unit shifts its product mix from coarse base material to finer aggregate or manufactured-sand feed without any structural change. Most buyers stock two panel sets and make the switch within one shift.
It depends on three things: feed moisture and clay content, how fine the cut is, and the headroom on your site. Tell us the material and the target sizes and we will specify the deck type and panel aperture with the quotation — this is the one choice where guessing costs the most later.
If your feed carries soil, fines or variable demolition debris, yes — a scalper removes the fraction the crusher should not process, cuts its wear and raises its effective capacity. On clean, well-sized quarry feed it is usually unnecessary; on topsoil, coal or C&D work it normally pays for itself.
The line covers 200–500 t/h depending on deck area, number of decks and aperture. The honest ceiling on a given mesh is set by moisture — damp feed passes less per hour than the same material dry — so quote the wettest condition you expect, not the average.
