A method of an active impact crushing including material destruction by oppositely directed and synchronized impacts of an actuator and reflecting elements in such a way that their impact surfaces are oriented normally to the velocity vectors of the material particles forwarded by the actuator, characterized in that in order to increase the efficiency and productivity of mineral crushing a forwarded by the actuator flow of material to be crushed is divided into two flows at the moment of the interaction with the active reflecting elements, wherein one of them comes into contact with the active reflecting element along a vector equal in quantity to a distance Rbetween a point of loss of a contact of pieces with a feed track and the working surface of this element, and the second one comes into contact with the active reflecting element along a vector R=R+(0,7...1,3)(D+KVt), wherein the material interacting along the vector equal numerically to Ris forwarded to a passive reflecting element having a concave working surface and reflecting the material into a zone located under the lower active reflecting element, wherein the center of the zone is disposed at a line connecting a rotational axes of the actuator and the lower active reflecting element at a distance of 3/4 of its radius, wherein the material interacting with the lower active reflecting element along the vector equal toRis forwarded into a space under the actuator. An active impact crusher implementing the described method is disclosed as well. |
