ELBA EMPG 1000
On the BAUMA, ELBA presents the newly developed ELBA Planetary Counterflow Mixer EMPG 1000.
Planetary counterflow mixers are mainly applied in block-making. This mixer type distinguishes itself by a rotor which turns around the vertical center axis and, depending on the mixer size, is fitted with 1 to 3 rotating mixing stars or agitators. Due to the rotational axis of the mixing stars the individual mixing tools of the mixing stars form a sort of planetary path.
In all the planetary counterflow mixers available so far, the speed of the mixing stars was considerably higher than that of the rotor, as the speed ratio between rotor and mixing stars is determined by the gear ratio chosen by the manufacturer.
The new gear of the ELBA planetary counterflow mixer EMPG 1000 enables a variety of ratios to be set between rotor and mixer, thereby allowing within one mixing cycle a range of variation of mixing kinematics unknown so far.
The advantage of the possibility of adjusting various speeds is a targeted mixing effect. That means that the energy input and/or the speed ratio may be adjusted to the respective mix. Additional advantages are the targeted energy input in the mixer and, thus, the possibility of minimizing wear. A fact that, in view of constantly progressing development of concretes and continuously rising energy costs, is of increasing importance.
