The Unique Oversize Grain Separator

The Rubble Master OS100GO! mobile oversized grain separator: the cost-effective solution for graded materials. Only one loader is needed for the RM100GO! to crush feed material at maximum throughput with minimum wear in a single pass. The OS100GO! is easily fitter to the crusher’s discharge belt using quick-release levers, maintaining unrestricted movement of the crusher around the site. Four comb cascades reliably screen the material to the defined grain size. The refeeding belt provides a closed-circuit system.

Rubble Master OS100GO! — CE-Certified Grain Achieved in a Single Pass

Rubble Master OS100 recycling asphalt

Together, the RM100GO! crusher and OS100GO! over-sized grain screen form a mobile system to produce CE-certified cubic final grain to a standardized size — at the highest throughput and with low wear to the machinery. The OS100GO! is fitted to the crusher’s discharge belt using quick-release levers, ensuring unrestricted mobility of the crusher around the job site. Four comb cascades reliably grade the material to the defined grain size with the return conveyor belt providing a closed circuit system. Both machines are transported with just one low-loader and are ready for operation within 20 minutes of arrival on site. Power is supplied from the crusher generator.

  • Defined final grain size achieved in single screening
  • 100% separation of oversized grains using 3+1 comb cascades
  • Straightforward and cost-effective solution for obtaining graded material
  • Reduced fine grain content since it never reaches the crusher
  • Comb cascades can be adjusted to each application
  • High discharge level — 9 ft 1 in (2.77 m for fine particles)
  • Power supplied from the crusher generator
  • Production capacity of 200 tons/hr (220 tonnes/hr)
  • Screen range 7/8 – 2-3/8 in (22–60 mm), resulting in grain size of 0/24 to 0/60
  • Quicker return on investment that with stand-alone screens
