hamos EMS and hamos KMS electrostatic mineral separators

With the hamos EMS electrostatic minerals separators, you can separate mixtures of minerals in a dry way, such as, for example, quartz and feldspar, into their individual constituents. Here, feldspar is separated and the quartz concentrated. By use of the tribo-electric behaviour of the individual minerals, the hamos EMS separates your mixed materials with little effort into single-sort material fractions.
