Continuous metal baling machines are also known as hopper-type briquetting presses, primarily used for compressing metal scrap into blocks. They can expel some liquid, increase bulk density, facilitate stacking, and recycle. They are particularly suitable for materials with a high original bulk density. By using a hopper for material storage, they allow for continuous feeding and compression, reducing downtime for loading and enhancing production efficiency. When combined with conveyors, they can easily integrate with existing production equipment to form an automated processing line. Therefore, they are widely used in situations where materials are difficult to compress, where a high degree of automation is required, and where they need to form a production line with other equipment.
