Watch the video: Sierra introduces HD3C-2020 three-compression baler

Sierra International Machinery has introduced the HD3C-2020 three-compression baler,  a stationary, 170-ton machine made with the highest degree of engineering. Equipped with four 125-horsepower electric motors, the HD3C-2020 produces high-density ferrous scrap bales.

According to Sierra, high production and versatility make the HD3C-2020 a profitable performer in virtually any scrap yard. These new units are equipped with a loading hopper and a compaction chamber with three movable walls, which by progressing in succession, realize the volume reduction. The compaction chamber surfaces are lined with replaceable, bolt-in tongue and grooved Hardox 450 wear-resistant machined steel liners.

For users of the HD3C-2020 baler, once compaction chamber is filled, a first hydraulic piston carries out the first volume reduction, and then refines material in a second compaction chamber. These machines are equipped with knives capable of cutting any metal scrap interposed between the hopper and the first chamber. At this point, a vertically disposed presser induces the second reduction in volume by leading material into a third compacting chamber. 

The final density of the pack is obtained with a third transversal pressing by a third presser. The package thus obtained is ejected through an exit door, being able to be pushed by the same presser that made the third pressing.
