To provide a crushing apparatus in which a raw material collides at a higher speed than launch speed.
A pair of rotary bodies having radially formed impellers are arranged to face side surfaces and are rotated at a high speed in the opposed direction to each other to form an opposed launch apparatus. The surroundings of the opposed launch apparatus is surrounded with a cover. A high speed rotating launch body having the radially fixed impellers and provided with a raw material receiving part in the center part and a high speed rotating collision body provided with the receiving impeller radially are arranged so that the raw material collides with the receiving impellers. A raw material charge part and the opposed launch apparatus communicate with each other through a raw material forcibly feed apparatus. A quantitative feed cylinder in which a discharge port is formed is charged in the rotating body or the raw material receiving part to unable to rotate. A quantitative feed frame body on which partition impellers are radially formed is charged in the quantitative feed cylinder rotatably.
