摘要： The invention relates to a method for manufacturing dispersed mineral products by grinding the mineral raw material, sizing the same in a flow classifier, sorting the same in dispersion in air, and eliminating the dispersion air. Also disclosed are devices and installations for carrying out said method. In prior art, mineral raw materials cannot be purified or are purified very inefficiently such that only very pure and high-quality starting raw materials, which are available in limited quantities only, can be used for manufacturing high-quality dispersed mineral products, especially fillers. The aim of the invention is therefore to create a method for manufacturing dispersed mineral products, particularly fillers, in a dry process as well as devices for carrying out said method. Said aim is achieved by triboelectrically charging the dispersed mineral particles of the particle-air dispersion during the sizing process and directing the same through an electrostatic separation chamber in order to separate the foreign particles from the valuable particles.
摘要翻译：本发明涉及一种通过研磨，分级，并在空气和扩散空气的沉积分散在矿物原料的流分类排序，以及用于实施该方法的装置或系统制备分散矿产品的方法。到目前为止，矿物原料可以非常低效或不进行清洗。因此，只有非常纯和高品质输出的原始材料可以用于生产高质量分散矿物产品，在使用特定的填料，但只适用于有限的程度。因此，本发明基于这样的目的以提供用于生产分散矿物产品，特别是在干燥步骤允许和装置填料的用于执行该方法的方法。这个目的是根据本发明的是，所述颗粒和空气分散体的分散的矿物颗粒被摩擦充电中分类和被传递通过静电分离室从Wertteilchen外来颗粒分离。
