The aim of the article is to discuss possibilities of production of aggregates with increased content of regular particles, on some well-known examples, as well as presentation of methods of aggregate production, which was not previously present in the industry. Traditional aggregate production circuits require application of three or four grinding stages (depending on the particle size of the feed), but for fine particle fractions of aggregates irregular grains occur on average approximate content of 10%. The innovative technological circuit can produce the aggregates with the content below 3% irregular grains, even in a single- or two-stage crushing circuit.
