Kreuzlingen, Switzerland — swissRTec AG, a company specializing in recycling technology, has announced the production of its largest delamination mill to date. swissRTec AG sells technology and mechanical systems to the recycling industry on an international scale. They are a leader in designing, building and commissioning turn-key e-waste, scrap metal and ASR (automotive shredder residue) recycling facilities.
Renowned for the delamination mill
swissRTec’s core focus is the shredding, delamination, separation and recovery of high yield and quality valuable raw material from composite waste streams such as waste electrical and electronic equipment (WEEE), cables, printed circuit boards, mixed scrap metal, aluminium composites and other items. The company is renowned for the development of its industry-leading delamination mill, an „impact mill“ which uses thousands of collisions to break down pre-shredded composite materials, isolate various components then mill them into tiny, smooth balls which are easily separated.
The CCM20RT is the largest mill swissRTec has even buildt in in the company`s history. Boasting a two-meter rotor diameter with a weight of 21 tonnes and up to 630-kilowatt drive, this new delamination mill is a dominant force in the swissRTec warehouse. More than a decade of experience has gone into designing and building the mill, along with the companion systems for complete milling and separation.
Digging deeper into waste
„The 2015 European Union regulations requiring a 95 percent End-of-Life (ELV) recycling rate coupled with the economic benefit of recovering more materials from ASR has pushed the recycling sector to dig deeper into their waste in an effort to recover more materials,“ says Mario Zoellig, CEO of swissRTec. „Metals are one of the first materials to turn to when looking to increase recovery rates of recyclable materials from ASR. The metals typically left behind in ASR are those which are most difficult to separate. These metals are of a significant value with a high copper content, thus recovering the metal fractions is an attractive prospect for recyclers.“
Zoellig also noted that the new mill was produced to meet the growing trend in the marketplace for larger recycling systems. „The machine is also needed because of growing demand within the auto shredder residue sector for a high capacity mill capable of producing unrivaled liberation and ball-shaping of metals alongside a machine which is rugged enough to withstand the rigors of ASR processing.“
High-efficient drive, lower energy cost
The CCM2ORT, as well as swissRTec’s smaller delamination mills, the CCM10 and CCM15, will be equipped with new, high-efficiency drive systems. These systems will not only increase the efficiency of the delamination mills by 5 to 7 percent, but operators will also benefit from the lower energy cost, seeing at least a 5 percent reduction. With many mills running in three shifts at a rate of more than 4,500 hours per year, the productivity increase and cost savings are substantial.
The swissRTec SRT2 system, which incorporates the delamination mill and separation system is in operation in numerous ASR plants worldwide. The system allows a mixed composite material to be inputted and through the frictional forces applied in the delamination mill, the metals are delaminated and ball-shaped. Through subsequent screening and density separation steps, the valuable metals can be recovered.
