These high-resistant cast elbows are minimally influenced by the abrasion of the material due to their design and are used in highly durable die-cast bodies for long-lasting abrasive materials. By acting as a bearing in the elbow, dynamic friction is minimized and the classical elbows in sharp elbow turns are prevented. With its extended curved design in the elbow, the features play an important role in the transfer of coarse particulate materials at high speed with Blower during the filling with silobas. As the body structures are very compact, they can be easily assembled and dismantled. They can be used on the conveyance line, especially vertically, if preferred. High abrasive materials can be used safely in all material handling systems.
