Stokkermill designs and produces innovative machines and plants for the grinding, granulation, shredding and separation of nonferrous metal scrap, for aluminium processing, preparation and recycling, for the recovery and recycling of copper and aluminum cables, for the recycling of electrical and electronic materials (WEEE), for the recycling of PCB boards and printed circuits ....

Dense Medium Separation

minerals prior to more intensive, downstream processing. Preconcentration has been practiced in industry for many years, and is gaining greater interest as the industry copes with processing lower grade, more difficult ores, typically requiring finer grind sizes and higher energy costs. The benefits of preconcentration are as follows:...

Cyclone Mill Twister

The cyclone mill TWISTER is specially designed for the processing of foods and feeds for subsequent NIR analysis. The optimized form of rotor and grinding chamber generates an air jet which carries the ground sample through the integrated cyclone into the sample bottle. The air jet prevents the material from heating up, thus preserving the moisture content....
