No other pipe conveyor system is so fully developed, installed in so many applications and so successfully tested in operation. KOCH Pipe Conveyor Systems: Setting New Standards.

3 The Superior Features. Conveying in tight spaces KOCH Pipe Conveyors integrate optimally in existing plants, and minimize conveying distances, regardless of the landscape parameters, thereby permitting cost effective line arrangements. Dust free with minimal noise emissions, securely protected KOCH Pipe Conveyors transport bulk materials dust free with low noise emissions and totally enclosed over roads, tracks, waterways or open seas, through existing plants, over public streets, in environmentally protected zones. Even contaminated materials are conveyed without any negative environmental impact. For all types of topography, flexible and innovative KOCH Pipe Conveyors easily handle long distances and problematic topographic areas. Customized designs incorporate complex client needs: downhill conveying in difficult topographies; conveying various materials in one system. Whatever is technically possible, we can implement based on our experience from 190 operating systems and relying on the innovative competence of the market leader. Cost effective and reliable Limited spatial requirements, elimination of high cost and maintenance intensive transfer stations as well as secure conveyance without expensive housings assure the cost effectiveness of the KOCH Pipe Conveyor system.

4 Fully Developed Technology, Operationally Tested Details. Each KOCH Pipe Conveyor incorporates extensive know how for dealing with the most varied types of materials and the experience from implementing more than 190 systems. Fully developed technology as well as the most state of the art planning and design aids such as, for example, special software and extensive data banks, form the basis for the success of the KOCH Pipe Conveyor. Numerous specially developed design elements, tested and optimized in actual operation, make all the difference. Thus, to assure the highest level of reliability even with widely fluctuating load factors, the belt construction of the KOCH Pipe Conveyors is designed using the finite element method and computer simulations. Using overload panels and a level monitor for the material flow, the KOCH Pipe Conveyor in its base model provides a double guarantee against overfilling. Guide stations along the standard conveyor sections always hold the belt in the proper alignment along the entire line. The belt scale, which can be installed in the closed belt pipe section, was specifically developed for use in the pipe conveyor. In the material loading area, the conveying belt is open. The conveyed material is supplied in the same way as in a conventional belt conveyor. Then special devices enclose the belt carrying the conveyed material. The diameter of the closed pipes can be selected depending on the conveyed material between mm for conveying volumes up to 9,200 m 3 /h. ply: steel or fabric At that point, the belt forms a sealed pipe for the entire conveying line. Thus, the content is protected against external influences while the environment is protected against any potential material losses. The flexible belt pipe design allows for directional changes without requiring transfer stations thereby enhancing both cost effectiveness and operating reliability. The belt opens on its own before the material discharge point and the material is discharged. conventional discharge point Following the material discharge, the belt is closed again this excludes the possibility of contaminating the conveyor line with spilled material. Panel A multitude of supplementary components from spillage conveyors through belt turning stations for the simultaneous conveying of different materials complete the offerings of the KOCH Pipe Conveyor line and lay the foundation for the development of new conveying designs for new tasks, new materials, and new applications. And do it reliably and according to time schedules from the initial layout through the bid process, fabrication, erection and commissioning. running side carrying side moulded edge feed belt loading point closed pipe feed belt belt idlers conveyed material return belt The heart of the KOCH Pipe Conveyor : an elastic belt with special design characteristics to assure a long service life despite widely fluctuating loads. The KOCH Pipe Conveyor in Operation Ring distributed idlers guide the belt pipes in the KOCH Pipe Conveyor to the discharge. A proprietary system assures quiet operation. Special mechanisms guarantee that the belt pipes are not overloaded.

5 Customized Designs for Every Application.
