The ContiTech Conveyor Belt Group developed a more troughable version of the anti-stick ContiClean® A-H conveyor belt (Fig.), the surface of which is specially designed to handle ultra-sticky material like desulfurized gypsum, unfired clay, titanium dioxide or wet ash. The new belt can be troughed to a greater extent, particularly at cold temperatures, thus increasing its conveying capacity. Even the narrower belt widths feature better troughing and running performance. These new benefits are attributable to an optimized rubber compound used in the production of the belt. The compound means that it is now possible to operate the belt conveyor at temperatures as low as – 25 °C. Thanks to its special surface properties, ContiClean® A-H does not become soiled even when handling ultra-sticky materials like clay and gypsum. Any caked-on material is gently removed beyond the materials discharge point by a scraper tailored exactly to the product. This means that conventional hard-metal scrapers are no longer an absolute necessity. The conveyor belt suffers less wear and tear, and its service life is increased enormously. The belt surface is resistant to ageing and weathering, it is antistatic as well as oil and grease resistant, as required.
ContiTech developed this new belt type in collaboration with Olberts Gummi- und Fördertechnik GmbH, Krefeld, Germany, the company marketing the product in Germany. ContiClean® A-H is initially available in the standard EP 400/3 version. Distribution of a belt with greater belt stiffness is also planned. The oil-resistant version Oil GM EP 400/3 can also be produced on request.
