平带输送机在输送物料过程中因平带跑边而造成撕裂损坏的情况时有出现。最初曾使用立辊挡住平带两边来防止,其结构与安装调整虽简单,但因是强制性的,易损坏平带。后采用了引进项目的新技术——双向螺旋橡胶托辊(见示意图)。由于该辊在工作时产生螺旋力,起着稳定平带控制跑边的作用。另外,还将平带 Flat belt conveyor in the process of conveying materials due to flat belt running tear caused by the damage occurred. Initially used to prevent the use of vertical roller block both sides of the flat belt, the structure and installation adjustment is simple, but because of the mandatory, easy to damage the flat belt. After the introduction of the project’s new technology - two-way spiral rubber roller (see diagram). As the roller produces a spiral force at work, it plays a role of controlling the running edge with a stable flat belt. In addition, it will be flat belt
