兖州矿业(集团)公司济宁二号煤矿总结了对带式输送机的运行经验,认为使用精度较高的托辊和高性能的输送带有利于减小输送机的工作阻力。实践证明,缩小托辊间距可减小模拟摩擦系数,但阻力总值会增大,除了在卸载点为保护输送带外在一般承载段不要加大托辊密度。与此相反,国外通常采取增大托辊间距的方法来降低阻力总值,但设计和安装要以充分的动态分析和优质的托辊为基础,才能确保带式输送机的可靠运行。该矿井下北翼带式输送机使用35°槽角前倾偏置托辊组和平行下
Yanzhou Mining (Group) Company Jining No. 2 coal mine summarized the operation experience of the belt conveyor that the use of high precision roller and high-performance conveyor belt is conducive to reducing the working resistance of the conveyor. Practice has proved that reducing the roller spacing can reduce the simulated friction coefficient, but the total resistance will increase, except in the unloading point to protect the conveyor belt in the general carrying section do not increase roller density. On the contrary, foreign countries usually adopt the method of increasing the roller spacing to reduce the total resistance value. However, the design and installation should be based on sufficient dynamic analysis and high-quality roller to ensure the reliable operation of the belt conveyor. The mine north-wing belt conveyor uses a 35 ° slot angle forward offset bias roller set and parallel
