Centrifuge Binder Extractors

Centrifuges are the most common binder extraction method, not requiring the heating of the solvent. Centrifuges are compatible with a wide range of chlorinated solvents, such as TCE and PERC. Special explosion-proof versions are available when flammable solvents are needed. High-speed filter-less centrifuge are then used to perform filler separation from the solvent solution.

Centrifuge Binder Extractors are used for the determination of bitumen percentage in bituminous mixtures.

All our models comprise a removable precision-machined rotor bowl housed in a cylindrical aluminium box.

They are driven by an electric motor fit with AC drive (inverter) with the double function of speed control up to 3600 r.p.m. regardless of the frequency (50 or 60 Hz) and electrical braking.

The centrifuge can be set for the automatic speed ramp up to 3600 r.p.m. or to any intermediate speed by the front knob. A digital display monitors the frequency, which is proportional to the speed.

The rotating unit is suspended on the base by four calibrated springs, which assure a perfect stability all over the test. The cover is precisely machined and fit with solvent resistant gasket to avoid leakages.
All models are fit for emergency use, thanks to a secure hand brake system.

Two capacities and two versions available:

Standard 1500 and 3000 g cap. (75-B2212,75-2214; 75-B2312,75-2314)
Explosion proof 1500 and 3000 g cap. (75-B2222; 75-B2322)

Possible upgrade

The standard models can be upgraded with an electromagnetic system to prevent the opening of the cover during rotation. This option (see code 75-B2210/UP1) is applicable on standard models only and has to be factory installed.

All centrifuges are supplied complete with 100 filter discs.
All centrifuges can fit different capacity spare bowls (75-B0022/2 and 75-B0023/2)

Start/Stop button
Speed control knob
Digital display.
