The metal chip briquetting machine can directly cold-press powdery cast iron chips, steel chips, copper chips, aluminum chips, and high-quality mineral powder into cakes, which are convenient for storage, transportation, and recycling. After being pressed into blocks, it is put into the furnace for recycling and the loss is low. The whole production process does not require heating, additives or other processes, and it is directly cold-pressed and formed, and the original material is kept unchanged while forming. For example, casting chips are used instead of cast iron after forming. For castings of special materials, recycling is more meaningful.
