A casting granulated metal equipment by a short flow was developed, which is comprised of pre-heating chamber, heating furnace, ceramic pipe used to transport the molten metal, the holding furnace, the drip nozzle and the cooling tank etc. The equipment can accomplish preheating the ingot, melting, holding temperature and the polluting at the same time. The preheating temperature of ingot is 100-120 °C. After the ingot is melted, the molten metal is transported to the holding furnace from the melting furnace by ceramic pipe, and the temperature in the holding furnace is 25-28 °C above the melting point of meta1. And the dwell time of granulated metal is 10-18 seconds in the cooling water box. Finally the granulated metal is directly delivered to the packing box by the bucket elevator. The granulated metal produced by a short flow has lower energy consumption and higher efficiency, and the energy consumption is 15-20% lower than that of the common flow.
