Hydraulic requirements
MB-S18 S4 hydraulic requirements

Only three hoses are necessary to operate the MB-S18 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 MB-S18 S4 should be equipped with hydraulic system with simple effect.

The required flow for the MB-S18 S4 is 120 l/min at 200 bar. Our tecnichians can verify the right values of flow and pressure available at your excavator with precise instrumentation (flowmeter).

The MB-S18 S4 can sieve several material, including concrete, natural stones, bricks, glass.

Production heavily depends on material's humidity, consistence, size of mesh, input size of material. Please contact us for more information about production.

The sieve has a diameter of 1600 mm, and an internal volume of 2.4 ㎥. For maximum performaces we suggest to load the sieve at a maximum of 1.2 ㎥.

The sieve rotates at a speed of 15~25 rpm, allowing for a smooth and complete separation of material. A faster speed would be in fact ineffective, limiting the total throughput of the screener.

Depending on the models of screener bucket, MB can supply several sieve sizes, in general from 10 to 100 mm, depending on specific requests. Sieve is cutted with laser and the shape of holes is round, for the 10 mm, and squared for higher sieving sizes.

The sieve is made of Hardox for sieve having hole sizes bigger than 40mm. It is made of iron for sieves having hole sizes between 10 and 40mm.

MB-S18 S4 excavator

To operate the MB-S18 S4 the excavator must have have hydraulic system with specifications set forth below, and enough lifting capacity and weigth to be stable during loading, processing and unloading phase. The recommended excavator weight is between 20~35 ton.

Please check the user manual of the excavator for the weight and lifting capacity, in case MB Technical Staff is happy to help you in finding out the relevant data for your excavator.

MB has successfully installed and operated the MB-S18 S4 on all main excavator's brands.


MB-S18 S4 screener bucket has been succesfully used in applications for demolition works, road construction, recycling, excavations, mines.
