The technology, which allows to process of granite crushed stones wastes thoroughly, is developed. Technology consists of two lines. The first line is granite crushed stones wastes modification for the purpose to produce of the filling compound for fine concrete. The second line is granite crushed stones wastes conditioning for the purpose to produce of some fractions how end products.
The method, which allows deriving equation for prediction of granulometric composition of crushed material in cone inertial crusher. However this method has two limitations. The first limitation is constant hardness of material. The second limitation is end granulometric composition depends only from parameters of cone inertial crusher.
At modern concentrating factories of 70 % of expenses of the electric power it is necessary on preparation of ore, and 2/3 these expenses fall on milling. Mills should provide demanded granulation of grinding at peak efficiency of crushing and minimally possible capacity on a drive. Therefore important correctly to choose a method for calculation of mills.
