Extrusion 6-2017

70 kompakt Extrusion 6/2017 ➠ ZUMBACH Electronic AG www.zumbach.com lump & neckdown detector an essential tool for faultless quality control. This detector is, in addition to other ver- sions, also available as a stand alone de- vice. A unique measuring principle and com- plex optics solution ensure immunity to stray and intense light whilst providing the highest detection accuracy and iden- tification of lumps and neckdowns in the micrometer range. n For continuous quality control, lump & neckdown detectors are as important as diameter gauges and spark testers. The line of KW 13TRIO and KW 33TRIO detectors capture with the highest accu- racy, reliability and velocity even the smallest lumps and neck downs in wires, conductors, optical fibres, cables, tubes and hoses. Thanks to the separate operating and display unit BAE 2 KW, the KW 13TRIO and KW 33TRIO can be fully operated and configured at the device. This unit features an illuminated graphic module to display values and messages, red, yel- low and green tolerance indicators for signalling operating states, a keyboard with function keys and a numeric keypad for manual instrument setting. The BAE 2 KW can be fixed at the operator sta- tion by means of the included wall mounting bracket (swivelling) or on the table. Thanks to its very compact design, the KW 13TRIO and KW 33TRIO fault detec- tors can easily be integrated in any extru- sion line or rewinding process. The mea- suring field is dimensioned in such a way that during the start-up, even extremely big lumps pass smoothly through. Its open design enables quick and easy threading of the product without stopp- ing production. A powerful micro processor as well as full digital signal processing, makes this Highlights • Complex optics allows: - Min. detectable fault height of 0.01 mm (at KW 13TRIO) - Min. fault length of 0.2...0.3 mm (at KW 13TRIO) • Full digital signal processing DSP • Very compact design Above: BAE 2-KW – Local Operating and Display Unit Below: KW 13TRIO – Lump and Neckdown Detector Lump & Neckdown Detection of the Highest Level put of 2500 kg/h. The thermoplastic scraps mainly consist of baled blown films coming from postconsumer recy- cled packaging. In order to increase the flexibility of the plant, a group of convey- or belts enables the two shredders to feed alternately two buffers on the lines. The decantation phase permits to sepa- rate the heavy objects and contaminants from the film whilst a pre-washing action removes other pollutants and dirt. The second high friction action is made dur- ing the wet grinding. Turbo Washer and Friction Washer ma- n AMUT RECYCLING DIVISION awarded two tenders issued by European leading companies both involved in the waste ma- nagement field. Each supply includes one twin plant suitable for the reclaiming and regeneration of thermoplastic polyolefin scraps to be transformed into granules. The water-saving concept of the AMUT patented technologies are well known all around the world because of the treated water that can be re-used thanks to spe- cial recirculation circuits. For the first pro- ject, the two lines will process, working in parallel, LDPE scraps with a total out- Double Twin Plants for Polyolefins Recycling chines perform an intensive and con- tinuous washing and rinsing action. The process washing water can be thermally adjusted and conditioned by chemicals/detergents to increase the cleaning efficacy. The flakes are separated from water and conveyed to the centrifuge machine for the drying phase. A hot-air drier reduces the humidity value of the flakes and makes the material suitable for the ex- trusion processes. For the other project, AMUT will supply twin lines for washing and pelletizing of
