Hydraulic briquetting press (chip packing machine) is to melt down and compress metal Chips into briquettes by cold pressing technology. Those briquettes are 3-6 kg each, and they can replace waste steel, copper, iron or aluminum as row materials, so it is benefit for reducing burning of metal. It is easy for store and transportation. It is no need to warm up, add additives or other craftwork during the whole progress of work. After pressing, the block’s density can reach 5-6 ton/m3 (without any adhesive). 1.
