The hydraulic metal chip briquetting machine is mainly used to press various metal chips (iron chips, copper chips, aluminum chips, etc.), powdered metal powder (iron powder, aluminum powder, copper powder, lead powder, etc.), smelting additives, sponge iron, etc. into high-density cylindrical cakes (weighing 2-8kg) without adding any adhesive, and the cake density can reach more than 5T/M3 (the density of pressed cakes is different with different raw materials), The pressed cake can be directly put into the furnace for use. The grades of cast iron can reach HT200-250, saving about 700 yuan per ton of castings.
