New System by Danieli Henschel – The Power-S

The manufacturer of equipment to process metal recycling scrap presents its latest technical innovation developed for the heavy-duty CIB shear range. 

The range includes shears with cutting strengths ranging from 800 to 1600 tonnes, equipped with a lateral precompression box six, eight or ten meters long. The latter is equipped with an articulated lid and a lateral reducer on either side, forming the compression box. The lid covers and compresses the scrap, thus closing the box. The reducer compacts the scrap by following a lateral movement towards the center of the box to prepare the product which is then pushed by the reducing ram towards the shear head for the shearing operation.

The Power-S system, patented in 2014, is installed on the lateral reducer of the pre-compression box, to process heterogeneous metal scrap during treatment and densify it to the maximum. This innovation is based on a more versatile use of the lateral reducer activated by very high-capacity hydraulic jacks, authorizing either a parallel movement or an adjustable angle movement. “Contrary to our competitors who propose one or the other of these movements but never both, we thus offer our customers the possibility to benefit from a single machine capable of treating and densifying all of the types of metal scrap present on the market: mixed or block scrap, and either heavy and thick, or voluminous.”

Further stated benefits

Thus, during the same working cycle, the lateral reducer can start to compact the bulk scrap in the box using a parallel movement for rapid compression. Then, in a fraction of a second, it can switch to an adjustable angle movement when the presence of a voluminous block of scrap is detected. The lateral reducer then moves into the most appropriate position, following an angle of attack that is automatically defined. It then presses upon a limited surface of the block in question to break it by exercising maximum pressure on the block. This compacting pressure is impossible to achieve with a parallel movement, since the contact surface with the scrap is much too large in that case.

The main strength of the Power-S system, says Danieli Henschel, lies in its versatile management of the movements of the lateral reducer and the lid, which can be both automatic (entirely automated working cycle) or manual, using a radio-controlled device or a control booth. Due to its innovative PLC program and hydraulic circuit management, the Power-S lateral reducer always applies the maximum possible force exerted by the hydraulic jacks, whatever its position. “Thanks to the contribution of the new technology, we can offer customers heavy-duty, high production capacity shears, equipped with a compression box offering a versatility/compacting pressure ratio unparalleled on the market today that will revolutionize the metal scrap treatment sector.”
