Hydraulic requirements
BF80.3 S4 hydraulic requirements

Only three hoses are necessary to operate the BF80.3 S4, IN, OUT and DRAIN.

Under specific conditions the bucket can be adapted to work also only with two hoses, without drainage. In this case the excavator maximum back-pressure at any time in the system must be lower than 10 bar.

The reccomanded excavator for the BF80.3 S4 should be equipped with hydraulic system with simple effect.

The required flow for the BF80.3 S4 is 150 l/min at 215 bar. Our tecnichians can verify the right values of flow and pressure available at your excavator with precise instrumentation (flowmeter).

The BF80.3 S4 can reduce concrete, natural stones, bricks, glass etc., to a size between 20~120 mm.

It can produce up to 34 ㎥/h which means about 51 ton/h if we consider concrete with an average specific weight of 1.5 ton/㎥.

The real throughtput can vary depending on the input and output size of material, its humidity, the presence of soil, etc.

The best way to obtain a high throughtput (production per hour) and a low wear of parts and jaws is to sieve the material before size reduction process. In fact, demolition material contains a lot of sand, soil and dust, that doesn't need to be reduced.

Please refer to our Screener line-up for this scope.
