High-Speed TEXREJECT eject gate
Fast acting eject gate TEXREJECT is used to remove metal contaminants from pneumatically conveyed textile fibres (by pressure and also by vacuum). Mostly is the eject gate used together with the metal detector METRON 05 PowerLine that detects the metal particles even at a transport speed of 30 m/s. Subsequently, these metals are reliably ejected by the high-speed TEXREJECT unit and the cleaned product is free of metal contaminants. The fast acting eject gate is designed so that the rejection takes place very quickly - in 0.05 seconds. This enables to reject metals even at high transport speeds and reduces good material loss to a minimum.
As the structure of the eject unit is very robust and durable, no wear even after 300,000 eject cycles is visible.
As standard, the eject gate is installed into pipes with a diameter of 220, 250, 300, 350 and 400 mm. On request, the unit can be supplied also for other pipe diameters and shapes.
In combination with a collection container, the eject gate is also suitable for vacuum transport.
Installation of the reject unit is easy and fast.
Industrial metal detectors for pressure pipeline transport are designed to inspect bulk materials conveyed pneumatically — both under pressure and by vacuum. They are most commonly used by plastics processors (granulate, regranulate, flakes), textile fibre manufacturers and recyclers, the chemical industry and pharmaceutical operations. The detectors capture free metal particles as well as metals hidden as inclusions inside a granule or fibre, without interrupting material flow.
The detector is integrated directly into the pneumatic pipeline. The material being inspected passes through the detection coil, which captures the signal generated by the presence of a metal contaminant. Upon detection, a high-speed rejection flap opens automatically, the contaminant together with a portion of material is diverted into the reject chute and the flap returns to its original position. The entire cycle is fully automatic. With a switching time of 0.05 s, losses of good material are minimal.
Sensitivity depends on the aperture diameter, material speed, density and other parameters. As a guide: the P-TRON 05 GM V2 with a Ø38 mm aperture detects an iron sphere from 0.4 mm diameter and a stainless steel sphere from 0.8 mm. The P-TRON 03 FM with Ø38 mm detects ferrous and non-ferrous metals from 0.6 mm and stainless steel from 1.0 mm. We recommend verifying the exact sensitivity for your specific application by testing your material — tests are carried out free of charge with a guaranteed result within three days.
We offer aperture diameters from 38 mm (P-TRON 03 FM, P-TRON 05 GM V1/V2) up to 630 mm (METRON 05 PowerLine). All models handle conveying speeds from 0.5 to 30 m/s. We install detectors in both horizontal and vertical pipelines. Non-standard diameters and geometries are handled individually to order — contact us with your specification.
The P-TRON 03 FM, P-TRON 05 GM V1 and P-TRON 05 GM V2 models do not require a Metal Free Zone — they can be connected directly to existing metal pipelines. The METRON 05 PowerLine uses a patented design that allows integration without an additional sensor tube, making it immune to electromagnetic interference from the surrounding structure. Installation is fast in all cases and requires no extensive modifications to the line.
The High-Speed TEXREJECT eject gate is a high-speed rejection unit designed for use in combination with the METRON 05 PowerLine detector. It is used in applications where material passes through the pipeline at speeds of up to 30 m/s — typically textile fibres or granulated raw materials. With a switching time of 0.05 s and a robust construction rated for 300,000 rejection cycles without visible wear, it enables precise rejection of metal contaminants with minimal losses of clean product. The unit is suitable for both pressure and vacuum conveying.
