Crushing Theory. Crushing Theory. When solid particles of feed material are being reduced in size, they are first. distorted by straining and mechanical energy is stored in the solid in a similar. manner to energy stored in a coil spring. As more energy is applied, the material is distorted beyond their ultimate.
