[vc_row][vc_column][vc_column_text css_animation=”fadeInDown” el_class=”subtitle brun”]Fluidisation in the air<\/strong>[\/vc_column_text][vc_column_text]These dry condition techniques consist of fluidising light elements in an upward airflow in order to separate them from the heavier elements.<\/p>\n

In the tables (pneumatic or densimetric), the light elements are separated from the table (or \u2018deck\u2019) and descend from this table due its gradient. The heavy elements leave via the upper section due to the shocks imparted to the table.<\/p>\n

In the ZZ separator, the light elements are dragged by a rising current of air and recovered by means of cycloning. The heavy elements are recovered from the bottom of the separator\u2019s Z circuit.[\/vc_column_text]\n
