OS100
The Unique Oversize
Grain Separator
Rubble Master OS100
OS100 — Oversize Grain Separator
The RUBBLE MASTER OS100 mobile oversized grain separator: the cost-effective solution for graded materials. Only one loader is needed for the RM100 to crush feed material at maximum throughput with minimum wear in a single pass. The OS100 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.
- 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
