Non-mechanical force crushing methods include: blasting, ultrasonic, thermal cracking, high-frequency electromagnetic waves and water power. The most widely used grinding is to load a certain amount of grinding bodies (or grinding media) of different shapes and sizes into a cylinder, such as: balls, rods, short cylinders, or larger ores, gravel, etc. After the material (ore) to be ground is loaded into the cylinder, the cylinder rotates at a certain speed, so that the grinding body is driven to produce impact and grinding effect, achieving the purpose of grinding the material.

[0003] The crushing process is a very complex process of size change of material blocks (ores), which is related to many unpredictable factors. The main factors affecting the crushing process include: strength, hardness, toughness, shape, size, humidity, density and homogeneity of the ore; also including some external factors, such as the interaction and distribution of the ore at the moment of crushing. The crushing process is irreversible and does not occur spontaneously. The ore crushing process is caused by overcoming the internal cohesion between the internal particles of the ore under the action of external force. Before the ore is damaged by external force, elastic deformation occurs, at which time the ore itself is not damaged. When the stress reaches the elastic limit, permanent deformation occurs, entering the plastic deformation state. When the plastic deformation reaches the limit, the ore will be damaged, thus bringing many inconveniences to the sampling and testing work of the ore. The traditional crushing device adopts a toothed roll crusher, which adopts a low-speed extrusion crushing method, which not only has low production efficiency, but also has complex equipment structure and poor crushing effect.
