1. Loading
First, place the metal waste to be packaged in the feed port or material box of the baler. These scraps can be metal products, scraps, scrap iron, etc. of various shapes and sizes.
2. Start and hydraulic drive
After starting the baler, the motor drives the hydraulic pump to start working. The hydraulic pump draws hydraulic oil from the oil tank and delivers high-pressure oil to the hydraulic cylinder through a series of hydraulic pipes and valves. The hydraulic oil pushes the piston in the hydraulic cylinder, generating a strong thrust, which is transmitted to the pressure head or pressure plate connected to the piston.
3. Compression process
Under the action of hydraulic thrust, the pressure head or pressure plate moves into the material box where the metal scrap is placed, exerting huge pressure on the metal scrap. As the pressure head continues to advance, the metal scrap is gradually compressed and the volume continues to decrease. During the compression process, the gaps between the metal scraps are gradually squeezed out, making them more compact.
4. Forming and pressure holding
When the metal scrap is compressed to the set size or pressure, the hydraulic system will enter the pressure holding state and maintain a certain pressure for a period of time to ensure the stability of the shape of the metal block and prevent it from rebounding after the pressure is released.
5. Discharging
After the pressure is maintained, the hydraulic system controls the relevant valves to return the hydraulic oil in the hydraulic cylinder to the oil tank, and the pressure head or pressure plate returns to the initial position under the action of the reset spring or other reset device. At this time, the compressed metal block can be pushed out through the discharge port to complete the entire packaging process. Some metal balers may also be equipped with an automatic bundling device, which will automatically bundle the metal block after it is formed for easy handling and storage.
