FSM Grit receiving stations are laid out individually to suit customer requirements and can be produced as receiving stations for road sweepings, sewer grit or other grit.
The FSM grit receiving station comprises the basic units reception screening grid, screening drum and grit wash separator. The size of the  reception bunker depends on the  throughput and the material to be processed.  
FSM grit receiving stations combine high performance with low operating costs.

Functional principal
Grit material is delivered via suction truck or similar and tipped through the screening grid into the bunker. The screening grid is designed either as a fixed rack or a vibrating screen. The material is fed via a screw conveyor either to a pumping pit or directly to a grit wash separator. The grit wash separator separates the organic and mineral contents and discharges the washed grit in the required quality in accordance with prescription.

As an option, a screening drum can be fitted between the reception bunker and the grit wash separator. This enables the grit reception station to deal with road sweepings.
With the help of the screening drum, coarse material is separated from grit.
The grit gathers in a collection vessel together with spray water from the screening drum. The grit/water mixture is fed to a grit wash separator for further processing. Coarse material drops into a container or a screw conveyor at the end of the screening drum.
If desired by customer, the drum screen can be provided with a series of screening zones, where various fractions are separated by means of perforated plates of differing perforation size.
