    • The invention relates to a particle separator and methods for separating the particles of a mixture. The apparatus of the invention employs two field elements to create a field in the space between the field elements. The surface contact of the particles of the mixture, inputted into the space between the field elements, triboelectrically charges the particles. Under the influence of the field, the charged particles substantially aggregate on one of two counter-rotating agitators, disposed operably in the space between the field elements, according to their respective polarities. The rotation of the agitators brings the charged particles into a substantially field-free space in the vicinity of the output ports. Some of the charged particles leave the agitators under the influence of external forces to enter one of the output ports based on their charge polarities.
    • 本发明涉及一种颗粒分离器和用于分离混合物颗粒的方法。 本发明的装置采用两个场元件在场元件之间的空间中产生场。 输入到场元件之间的空间的混合物的颗粒的表面接触对颗粒进行摩擦电荷。 在场的影响下,带电粒子基本上聚集在两个反向旋转搅拌器中的一个上,其可操作地设置在场元件之间的空间中,根据它们各自的极性。 搅拌器的旋转将带电粒子带入输出端口附近的基本无场的空间。 一些带电粒子在外力的影响下离开搅拌器,以便根据它们的电荷极性进入输出口之一。

    • The present invention provides an electrostatic separation device to separate components of a mixture of particulates, said device including a means to electrostatically charge said particulates and a first roll and a second roll which are conductive, said first and second roll being arranged one above the other, said device including third and fourth rolls which are also conductive, said first and second rolls each producing a non-conductive output and conductive output, which proceeds respectively to said third roll and said fourth roll, with said first and second rolls producing a mids output, said mids output from said first roll proceeding onto said second roll. The present invention also provides a method of separating particulates from a mixture of particulates, said method including the steps of electrostatically charging said particulates and passing same over a first and second rolls which are conductive, whereby the non-conductive output and conductive output of said first roll bypasses said second roll, said second roll processing only the mids output from said first roll. The present invention also provides a separation plant having such a device or utlising such a method. The present invention further provides an electrostatic and magnetic mineral separation device having a roll onto which a feed of particulate to be separated can be introduced, said roll including a magnetic means associated therewith to allow magnetic forces to act on said particulates and thereby attract said particulates to said roll, said roll also being conductive and said device including a means to electrostatically charge said particulates so that conductive particulate is removed from said roll before non conductive particulate.
