Abstract
All industrial metallurgical enterprises produce and use milled materials obtained by crushing. In the global energy balance, the share of produced energy consumed for crushing is more than 5 %. This paper considers a scheme of the crusher with stops on a roll, the structure of which forms a complex stress state in a crushed piece under onetime action of normal and tangential stresses. It is shown that when generating a complex stress state in a fragmented piece of brittle material, the energy consumption is less by 30 – 40 % than when acting in a piece of linear normal stress. The authors developed a method for determining capacity of the drive electric motor of an energy-saving crusher with stop on a roll at design stage.
