The ContiTech Conveyor Belt Group has developed a more troughable version of the ContiCleanr conveyor belt, the surface of which is specially designed to handle ultra-sticky material like desulfurized gypsum, unfired clay, titanium
dioxide or wet ash. New benefits include superior troughability at normal and low temperatures and improved resistance to low temperatures.
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 optimised 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. All the familiar features of ContiClean A-H, like greater durability and lower maintenance cost, have been retained in the new version.
“With our patent we are the only producers worldwide who are allowed to make the new cold-resistant and troughable ContiClean A-H belt”, explains Hans-Jürgen Duensing, head of the ContiTech Conveyor Belt Group. The new ContiClean A-H provides ContiTech with additional sales opportunities. Thanks to its improved characteristics, the conveyor belt can also be placed in markets untapped so far.
ContiTech developed this new belt type in collaboration with Olberts Gummi-und Fördertechnik, Krefeld, Germany, the company marketing the product in Germany. The development engineers have definitely come up with a solution that hits home with customers. “Together, we’ve succeeded in getting an East European customer interested in our product”, reports ContiTech applications engineer Wolfgang Kerwel. Meanwhile, the belt has
been in service for some months and has fulfilled all expectations.
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.
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.
