Mobile aggregate screening
The SS-7018 is the standard aggregate grader: a 7,000 × 1,800 mm three-deck inclined box, 220–320 t/h, 100 mm maximum feed, 32.5 t on tracks. Three decks plus a fines conveyor give four products from one pass, which is what a quarry needs to sell a full catalogue rather than one sub-base grade.
From mining and construction to recycling, how SUHMAN tracked plants are put to work across very different site types.

Screening is where a quarry's margin is decided. The same rock is worth more as three sized products than as one blended pile, and the only cost of getting there is a deck arrangement and a conveyor. The SS-7018 is sized so that one unit keeps up with a 250–300 t/h secondary without becoming the bottleneck. A screen that is undersized for the crusher ahead of it quietly caps the whole plant.
The tracked chassis means the screen can follow the primary as the bench advances, and it can be repositioned to suit the stockpile layout rather than the other way round. For contract work, it also travels as its own load, so a producer can offer screening as a service without buying a crusher.
The box is mounted at a steep angle and driven in a circular path, so material rolls down the deck while the vibration lifts and stratifies it. Fines work their way to the bottom of the bed and through the mesh; coarse stays on top and reports to the end. The angle is the main operating variable: steeper means faster travel and higher tonnage but less chance for a particle to pass; shallower means better efficiency at lower capacity.
Decks are arranged coarse on top and fine at the bottom, so each grade only sees apertures it can pass. The three decks plus the undersize produce four fractions simultaneously, and changing a product means changing a deck rather than re-setting the plant. Because the motion is circular and the stroke is generous, the deck sheds wet material better than a high-frequency fine screen would, at the cost of some efficiency on the finest cuts.

The four questions buyers ask first about this machine - answered from the spec sheet, the cases library and the service programme.
Length buys screening efficiency on near-size material, which is where a short box passes oversize into the wrong stockpile. At 220–320 t/h and 100 mm maximum feed, the 7,000 × 1,800 mm three-deck box gives four products from one pass on 32.5 t of chassis.
Yes - 180–350 t/h from the jaw against 220–320 t/h of screening capacity, so the screen keeps up without a buffer stockpile. On a two-stage plant that is what allows the crusher to run at a steady setting instead of stop-start.
Deck count and deck split sizes are in the spec table above. Deck count decides how many saleable fractions one pass produces; the solutions pages map typical two-deck and three-deck splits to standard commercial gradations.
Standard build is 20 working days after deposit, before inland transport and sea freight; custom configurations are scheduled at drawing confirmation. Screen media ships packed with the plant so first-day production does not wait on mesh panels. Body warranty runs 18 months from commissioning or 3,000 operating hours, whichever comes first.
Specifications may vary depending on final configuration and project requirements. A dash or blank means the parameter is not listed for this model.
