    • The invention relates to an apparatus and method for purging charged powder particles from a mixture of said powder particles and ferromagnetic carrier particles. Purging is effected by moving the carrier particles relative to a first side of a support surface which supports said carrier particles, while attracting the powder particles towards an attracting surface which is spaced apart from said support surface and at a different potential than said support surface. The movement of the carrier particles is driven by moving the support surface relative to a plurality of magnets which are arranged on a second side of the support surface opposite to said first side, for attracting the carrier particles to said first side.
    • 本发明涉及一种用于从所述粉末颗粒和铁磁载体颗粒的混合物中吹扫带电粉末颗粒的装置和方法。 通过相对于支撑所述载体颗粒的支撑表面的第一侧移动载体颗粒,同时将粉末颗粒吸引到与所述支撑表面间隔开并且处于与所述支撑表面不同的电势的吸引表面,从而实现清除。 载体颗粒的运动通过相对于多个磁体移动支撑表面而被驱动,多个磁体布置在与所述第一侧相对的支撑表面的第二侧上,用于将载体颗粒吸引到所述第一侧。
