The reccomanded excavator for the BF70.2 S4 should be equipped with hydraulic system with simple effect.
The required flow for the BF70.2 S4 is 150 l/min at 230 bar.
Our tecnichians can verify the right values of flow and pressure available at your excavator with precise
The BF70.2 S4 can reduce concrete, natural stones, bricks, glass etc., to a size between 20~120
It can produce up to 30 ㎥/h which means about 45 ton/h if we consider
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
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.
