In order to improve the plasticity and adaptability of raw materials, it is generally required that the resulting billet has good uniformity, ideal particle gradation, more fine particles, and can finely crush various raw materials. In order to improve the gradation of raw material particles and make the raw material particles as fine as possible, it is generally necessary to put the raw materials into the grinding equipment for repeated grinding, which consumes a lot of processing time and electric energy, and greatly reduces the production efficiency.
