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 climinating 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 quantifies 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矿物原料制造分散的矿物产品的方法，其在流动分选机中调整矿物原料，将其分散在空气中，将其分散在空气中，并且使分散空气着气。还公开了用于执行所述方法的装置和装置。在现有技术中，矿物原料不能纯化或非常低效地纯化，使得只有非常纯净和高质量的起始原料（仅限于有限量化）可用于制造高品质分散的矿物产品，特别是填料。因此，本发明的目的是创造一种用于在干法中制造分散的矿物产品，特别是填料的方法以及用于实施所述方法的装置。所述目的通过在施胶过程中对颗粒 - 空气分散体的分散的矿物颗粒进行摩擦电充电并将其引导通过静电分离室来实现，以将外来颗粒与有价值的颗粒分离。
