The TailScrape working principle
Like AirScrape®, the TailScrape works according to the Venturi concept. The intelligent blade structure on the underside ensures that negative pressure is created in the conveying area. Nothing can escape through the millimeter-thick gap because the negative pressure allows air to flow in. Dust generation and spills are reduced by up to 100%. The TailScrape works without contact to the belt and can therefore be operated permanently without maintenance. Used together with the AirScrape, the TailScrape saves considerable costs and resources.
In addition, the strong reduction in dust generation and contamination meets the requirements for occupational health and environmental protection.
In the rear area of the transfer a metal sheet is used matching the contour of the belt trough. Ideally, the sheet is mounted at a maximum distance of 20 mm from the belt. The TailScrape is shortened to the distance between the two AirScrapes mounted on the side and bent to fit the trough. The TailScrape is fixed and adjusted to the sheet by means of slotted holes and lifting elements allowing almost no gap and contact to the belt.
