1、 I 摘 要 FU350 型链式输送机是广泛用于水泥、生料、煤粉等粉状小块状物料运输的 输送设备。 该机主要有头轮，尾轮，输送链，机壳及驱动装置等组成。链式输送机工作 时，机槽下部的链条向前运动，使槽内物料的内应力增加，物料颗粒之间的内摩 擦力随之增加，当物料的内摩擦力大于物料与机槽壁的外摩擦力时，物料便随着 输送链一起镶嵌做连续的整体运动。 利用物料的内摩擦力的特征，它在机槽内受到输送链在其运动方向的拉力， 使其内部压力增加，颗粒之间的内摩擦力增大，保证了料层之间的稳定状态，广 泛用于各种粉状小颗粒物料的水平、倾斜运输。 特点： 1、结构新颖，设计合理，链条强度高，运行安全可靠。 2、材质好
2、，转速底，磨损小，维修费用低。 3、驱动功率小，耗电少。 4、全封闭输送，无粉尘污染。 关键词：关键词：物料，内应力，内外摩擦力，拉力，稳定状态 II ABSTRACT Chain converyor FU350s use for the converyor of powder、litter block crispy materials such as cement、crude materials、coal power、ect.
