螺旋输送机设计选型的现代技术

螺旋输送机能有效输送非连续相离散物料。由于非连续相离散物料在螺旋输送机内的运动特性极其复杂，因此—直没有很好的设计计算模型。它的设计计算必须凭借设计者的经验，用类似的输送机类比。分散元模拟技术（DEM）能很好地预测到物料特性的变化（如颗粒形状、颗粒尺寸、颗粒与颗粒和颗粒与壁面之间的摩擦）对螺旋输送机性能状态的影响，以及不同结构尺寸的螺旋输送机产生的输送效果。并能使设计者直观、动态地观察到物料在运输设备内的运动状态。

Modern technology in the design and selection of screw conveyors

A screw conveyor,which is widely used in various industrial sectors,can effectively convey discrete non-continuous phase material.Because of the extreme complexity in moving status of the materials with discrete non-continuous phase in screw conveyors,there were no good model for the design and calculation.The designers must depend on the experience of a similar conveyor in design.Discrete element modeling technology(DEM) was used to predict the performance of the screw conveyor on the different material pr...
