Abstract
It is developed a novel method for clear separation of fine fractions of secondary crushed stone and a device for its implementation. This device is aerating-vibrating screen. Technological scheme of separation includes besides aerating-vibrating screen additional step of the smallest fractions separation using cyclones and bag filters. A method for calculating the aerating-vibrating screen is presented. It is expedient to use small fractions of crushed stone for dumping of roads and exits from roads, strengthening of weak grounds, landscaping, and also as filling ingredient in concretes and mortars, which reduces the cost of concrete by about 25%.
