A device produces pellets from pressed material, including a feeding apparatus for receiving pressed material, which is arranged in the region of a feeder screw, a pre-pressing chamber which can be fed by the feeder screw, a closable main pressing chamber having a main ram movable for compacting the content of the main pressing chamber, and an ejecting apparatus having a closing slide, and a cutting device for cutting the pressed material during or after entering the pre-pressing chamber, the device being designed to cut the pressed material supplied to the pre-pressing chamber via the feeder screw so as to provide cut pressed material in the pre-pressing chamber and/or main pressing chamber for the purpose of compaction.

A double-acting apparatus and method for manufacturing metal scrap compression materials, in which a variety of shapes of collected metal scrap are compressed into pieces having a standardized shape such that they can be directly loaded into a blast furnace, thereby enhancing productivity. Two compression chambers are disposed at both sides of a first compression cylinder such that metal scrap is loaded into the compression chambers. In particular, when one of first press plates moves forward inside a first compression space of one of the compression chambers, the other one of the first press plates moves backward and returns to an idle position.

A mixed collection and compression device for dust and thin metal includes a separation mechanism used to sieve a flowing gas therein into a dust-containing gas and a metal material; a filtering mechanism connected to the separation mechanism and used to filter dust in the dust-containing gas; an inert powder adding mechanism connected between the separation mechanism and the filtering mechanism and used to add inert powder into the dust-containing gas during transportation; a compression mechanism connected to the separation mechanism and used to collect and compress the metal material; and a power gas source used to provide a negative pressure environment for a gas inside the separation mechanism to make the gas sequentially pass through the separation mechanism, the inert powder adding mechanism, and the filtering mechanism. It has the effects of reducing the explosion risk and improving the safety of field work.

A metal briquetting system (MBS) driven by electric power and configured to process metallic scraps or powders into dense, compact briquettes is disclosed. The system utilizes precision-engineered gearboxes, actuators, and control to efficiently convert raw materials into solid briquettes. The MBS handles Computer Numerical Control (CNC) exit conveyor metal powder or chips with exceptional speed and reliability. The system is engineered to optimize compression chamber configurations, thereby reducing its footprint while supporting high processing throughput. Additionally, the system can be programmed to enhance energy efficiency, leading to significantly lower energy consumption relative to hydraulic briquetting systems and to create a much safer working environment.
